NAP5 – Meh !?

Do you remember where you were in 2011 when the results from NAP4 came out? I do. I was doing some upskilling in anaesthesia in New South Wales and the results of NAP4 lead me (and I am sure, many others) to change my practice. It was about the same time that FOAMed was taking off, so there was a renewed enthusiasm to challenge current practices, question dogma and seek to be ‘better’. Even now, several years later, I find myself referring back to NAP4 to confirm data and inform research in my favourite topic – difficult airway management.

NAP4 changed my practice - for the better
NAP4 changed my practice – for the better

So I was kind of looking forward to NAP5 – the fifth national audit project of the Royal College of Anaesthesia and the Association of Anaesthetists of Great Britain & Ireland. This audit examined the issue of accidental awareness during anaesthesia. This is perhaps one of the most feared complications for an anaesthetist….and indeed for a patient. The possibility of being awake yet unable to move (due to concomitant administration of neuromuscular blockade) is terrifying.

But the results of the audit have left me feeling a bit ‘Meh?’. There are 64 recommendations in the Executive Summary, but  a quick read of them just confirms what I thought we already knew – awareness can happen and good anaesthetic practice (which is essentially what the 64 recommendations summarise) can help mitigate this.

Perhaps that is a bit churlish. Audit is a tedious but necessary part of medicine. To quote Karim Brohi from #smaccGOLD when talking on the introduction of REBOA to a trauma service “you HAVE to sweep the floor….only then can you innovate

So what was the reported incidence of awareness in NAP5?

Thankfully awareness appears pretty rare in anaesthesia, with NAP5 suggesting a 1:19,000 anaesthetics overall. Not surprisingly the incidence is increased by 7.5x when neuromuscular blockade is used compared to when not. Having the patient swing at the anaesthetist during the procedure is a fair clue that they are awake, whereas paralysed patients can’t punch! Actually, that’s not strictly true – the isolated forearm technique is one way of screening for awareness – but the number of anaesthetists who use this is vanishingly small. Of course aware patients can mount other responses, such as increased heart rate, blood pressure etc – but then again, reliance on these is inaccurate and somewhat cruel.

If you take GA as a “treatment” for unwanted consciousness and take awareness as “harm”
then the NNT is 1.00001 & the NNH is 17,0000!
[Dr John Berridge, Doctors.net.uk]

 

Incidence of Awareness in NAP5

~ 1:19,000 anaesthetics overall

(1:18,000 with neuromuscular blockade vs 1:136,000 without paralysis)

High risk areas included cardiothoracic (1:8,600) and obstetric anaesthesia (1:670).

YEP – THAT IS RIGHT – 1/670 in OBS ANAESTHESIA

(before any smart arse comments, they DID exclude those having their baby under neuraxial blockade alone – clearly these patients are conscious and aware).

I wonder if the possibility of drug error contributes? The NAP5 authors mention presence of “antibiotic syringe” as being a particular risk – all the more reason to push antibiotics as soon as decision is made to go to section, then induce with usual anaesthetic agents. Interestingly I’ve herd anecdotes that the Poms don;t use propofol much for obs anaes (it remains off-licence for obstetric use in the UK!) – the older specialists insisting on use of thio.

I can’t recall ever seeing thio used in obs anaes in Oz; another indiction of how much dogma needs to be lysed, particularly when there is potential for harm. Hard to confuse propofol with an antibiotic, much easier to confuse thio!

Other risks included :

OBESITY (I suspect underdosing of induction/maintenance agents)

USE OF THIOPENTONE (probably because of 500mg/vial insufficient dosing in the lardy and possible use as bolus vs titrated dosing at induction Another thought is that propofol has some amnestic effect, so may confound patient recall of awareness when receiving thiopentone vs the Jackson Juice).

USE OF NEUROMUSCULAR BLOCKADE – amazingly it seems that many anaesthetists aren;t using nerve stimulator TOF intra-operatively. Interesting. Maybe I am obsessive about this?

Listen up emergency and critical care docs : Induction, Emergence and TIVA are particular risks

Other high risk stages of anaesthesia include the dynamic phases – namely induction and emergence. NAP5 suggests that 2/3rd of reported awareness episodes occurred during these phases. Again, not surprising as this is when a failure to establish post-intubation anaesthesia, accidental disconnections or residual paralysis on extubation are most likely.

How is those relevant to critical care and emergency clinicians? well, we all obsess about airway management, best choice of induction & paralytic agent (answer = “rocketamine”)…but we may become complacent once the ETT is passed and forget to establish quickly a post-intubation sedation plan. Even if we DO, infusions can be disconnected, pulled out – or, worse still, sedation may be inadequate for the time when your roc is still effective. Prehospital and ED doctors need to be as vigilant for awareness as anaesthetists in theatre – perhaps MORE SO as our patients are at risk.

“The post-intubation phase is a time of particular risk – the patient has been induced with ketamine, paralysed with rocuronium & tube placed without hypoxia or hypotension.
Failure to ensure adequate ongoing sedation may lead to accidental awareness in the post-intubation paralysed patient. Be vigilant!”

Of particular interest to me was the fact that accidental awareness was more than twice as likely during total intravenous anaesthesia as when using volatiles; again, not surprising as the latter allows end-tidal volatile monitoring. An extra risk was TIVA using non-TCI techniques eg: intermittent manual bolus of agent, fixed-dose regimens etc. rather than the established TCI techniques available on sophisticated pumps.

“When transferring patients, whether it be from ED to CT, from OT to ICU or from Dingo Creek to tertiary centre as an aeromedical retrieval, this is when patients are at most risk” 

This is a problem and something that all involved in management of critical patients should consider – namely that TRANSFER OF PATIENTS IS A RISK FOR AWARENESS.

What to do with the data?

The NAP5 data does give us up-to-date numbers for the incidence of awareness and I will use these in explaining risks to my patients, as I already do. Indeed it suprised me that one of the NAP5 recommendations was that :

“Anaesthetists should provide a clear indication that a pre-operative visit has taken place, identifying themselves and documenting that a discussion has taken place”

Doesnt eveyone already do this? Apparently not – whilst here in South Australia there is a separate anaesthetic consent form, there were none when I was in NSW (this may have changed). Colleagues in the UK seem content to allow the surgeon to consent for the procedure – whilst I can undestand that the gynae reg can consent for the surgery, I really dont see how he/she can adquately explain the anaes risks. But I digress…

But – what about those fancy BRAIN WAVE MONITORS?

Some of the important questions remain unanswered….we’ve had new anaes monitors rolled out into country, apparently on the pretext that depth of anaesthesia monitoring is mandatory. So someone ordered a bunch of machines with BIS monitoring. BIS or bispectral index is one form of proprietary EEG (pEEG) monitor, marketed as giving an indication of ‘depth of anaesthesia’. My preference is to use measurement of end-tidal anaesthetic gas to decide if there is sufficient volatile on board.

Testing the BIS monitor before  a morning case on KI
Testing the BIS monitor before a morning case on KI

At present, use of proprietary EEG monitors is NOT considered a standard in anaesthesia in Australia. Moreover there is some evidence that reliance on a particular pEEG number to decrease concentration of volatile is more likely to cause accidental awareness (fully awake BIS = 100, brain dead = 0. Sort of. It’s a bit more complicated, but you get the gist).

Like many others, I remain unconvinced of the role of BIS during general anaesthesia with a volatile agent.

POP QUIZ – HOW DO YOU ‘ZERO’ THE BIS MONITOR?
ANSWER – USE THE ORTHOPAEDIC REGISTRAR

 

Again, perhaps the most risky aspect of anaesthesia is when using intravenous anaesthetic agents in the face of neuromuscular blockade. This is particularly pertinent to my current role in retrieval, where it is not uncommon for critically unwell patients to be induced with ketamine, paralysed with rocuronium then placed onto a maintenance infusion (propfol, fent/ketamine, morph/midaz etc) – if there is an omission of post intubation sedation, an accidental disconnect or even an under-dosing, then awareness under paralysis is a real possibility. Where possible paralyse then allow to wear off and use appropriate ventilator settings to allow spontaneous ventilation in transit.

Which begs the question – should the role of pEEG monitoring be targeted to those patients who are paralysed and undergoing TIVA – typically retrieval & some ICU patients? I am not aware of a transport monitor that allows measurement of pEEG. Should we be using it for some of our intubated and ventilated patients? Interested in others thoughts on this….

And finally – a checklist proposed as the cure to reduce accidental awareness!

The authors also propose use of checklists during ‘high risk of awareness’ occasions (such as transfer of patients). Moreover, the NAP5 authors recommended :

“the use of an ‘anaesthetic checklist’ (easily integrated with the World Health Organisation Safer Surgery checklist) to be used after transfer of patient, to prevent incidents of awareness arising from human error, monitoring problems, circuit disconnections and other ‘gaps’ in delivery of anaesthetic agent”

 

Now it is no secret that I am a fan of checklists – I argued passionately (and a little rudely) for their use by airway experts at smaccGOLD – but I would also advice caution in their use

Whilst the WHO surgical checklist is lauded as reducing complications, this is utterly dependent on successful implementation. Sadly for many units the WHO checklist has been opposed from on high, without opportunity for team buy in or local modification. In these circumstances, a checklist can become worse than useless – it can be a danger. We’ve all got anecdotes of the checklist being completed after induction of anaesthesia, of the whole process being reduced to a pointless tick-box hurdle to be rushed through, rather than a cognitive rallying point.

We MUST be cautious of checklist fatigue.

As I said at smacc, pehaps their use is best reserved for routine only when there is full team buy in and the checklist is implemented by the frontline users – not imposed from on high. The benefits of a checklist in anaesthesia crisis are predominantly through a challenge-response of ‘have you considered X‘ rather than a cookbook ‘the next step will be to do Y‘ approach.

So is NAP5 a gamechanger?

I don;t think so. Reading the recommendations in the Executive Summary reads more like a description of how a good anaesthetic should be given. I hope I am not alone in reading the 1-64 recommendations and going “yep – do that – and that…

I don’t think it really addressed the issue of pEEG monitoring. Intuitively they may seem ‘sensible’ but I maintain that there use is probably best confined to the paralysed patient on TIVA.

Are there lessons here for emergency doctors, intensivists and retrievalists (not just anaesthesia)? Absolutely. It may be that awareness of ‘awareness’ amongst emergency clinicians is less heightened than the archetypal OCD-anaesthetist….and yet our post-rocketamine patients are at particular risk.

Be alert to the risk of awareness when managing a patient who has been paralysed and is being maintained on an infusion to keep them asleep.

 

I will leave the last word to that esteemed Professor of Hogwarts, Prof Mad Eye Moody :

ATACC Manual – Quality FOAMed

For those of you have been reading KIDocs over the past year or so will know that I am a harsh critic of the ATLS course (EMST in Australia). Not because I think it’s pants – it’s not. It does what it says on the tin, namely it teaches a basic approach to trauma management for the single responder in a community hospital. The A-B-C-D-E approach is easily taught and easy to recall under times of stress. I have no doubt that the ATLS course has done a world of good in bringing structure to trauma care worldwide.

I’ve been teaching on ATLS-EMST since 2006 and a course Director here in Australia for the past few years. In recent times I’ve seen how quickly FOAMed can narrow the ‘knowledge translation’ gap from concept to practice – and become increasingly frustrated that the ATLS-EMST manual doesn’t really address nuances of modern trauma care.

It should be borne in mind that the ATLS-EMST course is considered mandatory for credentialling in many hospitals. Like many other courses (APLS, ELS, ALSO, ALS) I think this is fine when setting a minimum standard. However it frustrates me that experienced clinicians are expected to repeat these ‘alphabet’ courses every few years.

Don’t get me wrong – I am not saying that experienced clinicians don’t need regular updates and ‘benchmarking’ – but it would be good if the content of the course built upon the basics, not just repeated the entry-level content. I have heard that post-Fellowship emergency physicians in the UK have been required to complete an ATLS course as part of revalidation – when the skills that they apply in their day-to-day job far outstrip those taught on ATLS.

And of course, successful trauma management isn;t just about knowledge and procedural skill. It requires an understanding of how a trauma team functions. We’ve all seen dysfunctional trauma teams, despite the individual excellence of the clinicians, dysfunction arises because of a complex interplay including human factors.

Last year the Australians kicked off the Emergency Trauma Management course (ETMcourse), which is aimed not to replace ATLS-EMST, but to offer content that includes cutting edge FOAMed good ness as well as apply principles of teamwork (clearly human factors are important in how a trauma team functions – or fails). You can read a review of the ETMcourse here.

Other courses such as the anaesthetists EMAC and the retrievalists STAR courses also explore some of these aspects, as well as more challenging scenarios – details on available courses here.

Introducing the Anaesthesia, Trauma & Critical Care Course (ATACC)

But there is another course – the ATACC course. I’d heard about this via doctors.net.uk and been in touch with the course organisers with a view to trying to get a course ‘down under’….which might be difficult! ATACC has an excellent reputation in the trauma world, for teaching real life scenarios in multi-disciplinary team. I am busting to attend one of these courses if I can get back to the UK

The ATACC Faculty include not just clinicians, but also luminaries of extrication such as Ian Dunbar (of the Holmatro extrication techniques app and book fame). Similarly the course is open to all – doctors, nurses, paramedics, physicians assistants, operating department practitioners – anyone who is involved in trauma. A far cry from the College of Surgeon’s ‘Advanced Trauma Life Support Course – for doctors’.

Screen Shot 2014-09-11 at 5.13.36 pm

 

ATACC Faculty includes Ian Dunbar (@Dunbarian) author of the excellent extrication manual sponsored by Holmatro – also available as a truly interactive app/iBook – worth every penny for anyone interested in prehospital care

 

ATACC Manual Available as FOAMed – PDF or iBook versions

 

So mega-kudos to the ATACC mob for launching their course manual as FOAMed – I’ve just got my hands on a copy and I can attest that it is thoroughly excellent.

Screen Shot 2014-09-11 at 5.01.13 pm

The PDF copy is available here

http://www.atacc.co.uk/e-learning/

or in iBook format via iTunes here

https://itunes.apple.com/us/book/anaesthesia-trauma-critical/id917866158?ls=1&mt=13

I cannot begin to tell you how good this manual is – it covers modern trauma management, is interactive and authoritative. It covers the usual trauma stuff, but is packed with some extra nuggets – I am a big fan of the MARCH approach and was pleased to see this included, along with some other adjuncts to haemorrhage control including haemostatic agents, clamps and the like. Up to date controversies (#dogmalysis) on topics such as cervical spine immobilisation are also covered – and my understanding is that content will be regularly updated.

Screen Shot 2014-09-11 at 5.17.56 pm

One of the strengths of the manual is that it covers trauma from the roadside, through retrieval, the ED and to ICU. It’s trauma run by traumatologists (did I just say that? Bah!) – not by surgeons. As such I recommend it to anyone involved in trauma care – prehospital clinicians & retrievalists, rural docs, EM types, anaesthetists, doctors, nurses, paramedics…

Awesome
Everything is Awesome When You Are Part of A (Trauma) Team

That the authors have made it freely available as FOAMed is truly humbling! I remember that it was only a couple of years ago that ATLS made their course manual available for non-attendees…and they still charge a packet for the hardcopy. There is an ATLS app – but the less said about that, the better.

The ATACC manual is true FOAMed – quality medical education, up-to-date and freely available because the ATACC mob believe in what they do.

Kudos to you. Seriously.

Loving the section on cervical collars - mentions the Brisbane protocol, decision-making rules, clearance in ICU etc

I’ll let you know if I ever get to an ATACC course in the UK and review it online. From what I’ve heard and seen of the manual, the three day intensive course must be orders of magnitude of awesomeness!

Meanwhile, I will leave you with this thought on the 9th edition of ATLS-EMST (attribution unknown, apologies)

...seriously - does EVERY trauma patient need a rectal exam? ATLS dogma still says YES (except on courses I direct)

IMSANZ 2014 – ‘FOAMed Taking Life Long Learning by Storm’

I have been asked to speak at the Internal Medicine Society of Australia & NZ annual scientific conference, which will be  held in Adelaide this September.

The idea is to introduce physicians to the concept of #FOAMed. I reckon this could be a tough gig….there are only a few physicians active on SoMe in Aus/NZ and I am not sure how well the anarchic, free-form and rapidly moving concept of #FOAMed will be embraced by them.

Whilst emergency and critical care physicians have been the main early adopters of FOAMed, I reckon that physicians lie somewhere towards the right of the ‘innovation adoption lifecycle model’.

Screen Shot 2014-09-03 at 8.45.49 pm

So my cunning plan is to try and entice as many of the audience in, by playing a short video during the one hour lunch break before the scheduled afternoon session.

I am in a concurrent, going up against local cardiologist Julian Vaule talking on NOACs (“novel oral anti-coagulants”) – or, as I prefer to call them “evil Big Pharma meds that aren’t all they are supposed to be and unlike rat poison cannot be reversed“.

Now I dont know about you guys, but I have sat through a load of lectures on NOACs…but I don’t reckon I ever sat through a lecture on tools for lifelong learning, on metacognition, on use of Social Media to filter educational content for self-development.

The video borrows from the meme of ‘taking life ling learning’ by storm(trooper) – a concept I first saw in a FOAMed lecture from Chris Nickson of LITFL fame, then taken up by others such as Andy Neill from emergencymedicineireland.

The video allows the inclusion of stormtroopers twerking and shufflin’  – what’s not to like? It struck me that these talks plus the video could be used by others when preparing an audience for FOAMed…(since originally posting, was contacted by Simon Carley of StEmlyns.org and asked if could use the video to introduce FOAMed at the 2014 College of Emergency Medicine conference in Exeter, UK this week. Nice to share)

Screen Shot 2014-09-10 at 9.01.13 am

I’ll bung up a slideshow of the IMSANZ on the day it is to be delivered – 19th Sept – as an example of a ‘flipped classroom’. Wish me luck! Gonna be a tough audience….

Resus Room Feng Shui

It’s been a pleasure to present at the biannual EMSA2014 (Emergency Medicine South Australia 2014) in Adelaide, South Australia.

Like smaccGOLD (social media & critical care conference, Gold Coast 2014), the audience was an nice mix of clinicians – grizzled old rural doctors, hardcore emergency physicians, vastly experienced emergency nurses and paramedics…as well as a nice smattering of students.

As always, I suffer from a degree of ‘imposter syndrome’ – what can a rural doctor possibly have to say of interest to this sort of audience?

Spot the Imposter
Spot the Imposter

Unlike smaccGOLD, many of the audience were naive to the concept of #FOAMed (free open access medical education) – so I opted to tell a personal story of how my practice as a rural clinician has changed in the past 2 years, shaped by the mentors in the photo above

“as a rural clinician, FOAMed means there is no longer an excuse for my lack of knowledge to be the weak link in patient care”

In order to close the loop, I’ve made a commitment to put my slides and relative links up on the blog for new FOAMed acolytes to explore.

This whole talk is of course based around the concept of managing oneself, the team, the environment as well as the patient – a concept taken from Cliff Reid’s excellent ‘Making Things Happen’ talk from smacc2013 in Sydney. Worth watching this talk as well as many of the other talks from the smacc conferences past, present…and future.

We’ve ALL got great talks, great slides, great ideas which we share in tutorials, at rounds, at conferences – the ethos of FOAMed is to share this educational content with colleagues around the world.

The concept has been enthusiastically taken on by clinicians in emergency medicine and critical care, who recognise the value of a means of rapidly disseminating information to discuss cutting edge concepts.

Of course once still needs didactic teaching, to read textbooks and to peruse journals as the foundation of medical education – but once one has achieved a degree of competency in the field and is looking to keep abreast of new ideas, FOAMed opens up a world of self-directed learning. It’s for finesse and mastery, not the basics.

Added to this are the advantages of learning asynchronously – listening to a podcast on the morning commute or at the gym…watching a video to reinforce the details of a practical procedure or to watch a conference talk…or even reading clinical conundrums posed on the myriad of EM and CC blogs out there.

As one explores the global FOAMed community, discussions are had with colleagues around the globe, allowing informal ‘corridor conversations’ with like-minded colleagues. Not only that, but experts in various fields give freely of their time and experience – it’s nice to be able to tap into (and even discuss) ideas with people like Karim Brohi, Scott Weingart and so on…

Finally FOAMed helps break down tribalism – we’re all interested in patient care and advancing clinical knowledge (whether our own, or the global sum). Some of the best contributors come not from ‘eminence-based’ medics…but from other arenas. I’ve learned a helluva lot from my colleagues in prehospital care, with many lessons applicable to rural, Ed and ICU environments. Ditto the involvement of nurses, paramedics, students, social workers, administrators – people with a different spin on the work we do.

So – don’t be scared – dive in, explore the FOAMed (free open access medical education).

Gar Pask – Anaesthetic Hero

I’ve been doing a bit of thinking about life-jackets after spending a few hours bobbing around in a heated pool during last week’s HUET (helicopter underwater escape training) course.

Whilst practicing in a pool is one thing, I did wonder how well one would cope if ditching in the cold waters of the Southern Ocean wearing a switlik & flight suit or immersion suit. Probably quite well – modern safety equipment has come a long, long way from it’s origins (the first description dates back to 870 B.C., with a stone carving showing Assur-Nassur-Pals’ army crossing a river wearing inflated animal skins as flotation devices).

“the bravest man in the RAF never to fly an aeroplane”

The development of modern lifejackets includes a vital contribution by British anaesthetist, Edgar ‘Gar’ Pask. His story is fascinating, not least for the fact that, like true eccentrics, he performed experiments using himself as a test subject.

pask03

Pask in flotation device

Pask is famous for having been asleep whilst completing most of the research for his thesis

In essence, Pask made three vital contributions, spurned on in part by necessary developments during WWII.

(i) the problem of ‘downed & drowned’ aircrew

Most of us are familiar with the “Mae West” – a US lifejacket considered the cutting edge in the war years. Whilst it did a great job of keeping downed aircrew afloat, sadly many airmen were found in a face down position. They survived bailing out of their aircraft, but drowned despite being kept afloat.

Edgar Pask was a British anaesthetist, seconded to the Physiological Laboratory in the RAR Research Station at Farnborough, UK under the encouragement of another anaesthetic great, Professor Macintosh. Pask’s doctoral thesis is infamous for being performed with the author mostly asleep – the reason being that Pask used himself as a test subject. He was anaesthetised and placed, unconscious, in a swimming pool whilst on a breathing circuit. By simulating an unconscious airman, Pask and colleagues were able to test a variety of different lifejackets, refining techniques such that modern lifejackets ensure the victim floats face up, rather than risk ending up face down in the Mae West lifejacket.

The video footage of this research is fascinating – a short clip is shown below. The experimental subject is Pask, intubated and breathing ether on a double-lumen, corrugated anaesthetic circuit, the tubing of which was weighted to neutral buoyancy. Essentially a Mapelson D circuit. He was then unceremoniously dunked in the pool, whereby he promptly sank.

(ii) the efficiency of different artificial respiration techniques

If downed aircrew were recovered, many expired when pulled form the water. The real problem here was actually cold water immersion syndrome – the redistribution of blood volume in a weightless water environment meant that cardiac output dropped markedly when aircrew were pulled (usually vertical) from the water. Attempts at artifical respiration were employed – in the 1940s, the Schafer method was most popular.

The second part of the above video shows an anaesthetised Pask undergoing various methods of artificial respiration whilst paralysed (at the 9:08 mark). They demonstrate Silvester’s method, Schafer’s method & Eve’s rocking method. Not currently approved by the Resus Council!

Silvester's Method

Eve’s Rocking Method

These experiments are remarkable (and a little unsettling) – Pask was paralysed and then underwent two hours of artificial respiration, during which time measurements were made of ventilation rate, tidal volume and O2 consumption. This was in the days before apnoeic diffusion oxygenation!

(iii) high altitude decompression ‘time of useful consciousness’

The RAF leased B17 ‘flying fortress’ bombers from the USA. These lightweight aluminuim-skinned aircraft apparently flew at the height of Everest, unpressurised – posing hazards of cold & hypoxia to the crew. Pask explored the effects of bailing out at such high altitudes – again, using himself and colleagues as test subjects. They were exposed to various hypoxic mixtures in a decompression chamber – the records are disturbing, essentially describing young men being asphyxiated and then allowed to recover.

Here is a description of Gar Pask being asphyxiated, whilst hanging vertical in a parachute harness in a hypoxic mix in a decompression chamber. Extreme hyperbaric medicine!

The period of anxiety was more prolonged than in the ‘descent’ from 55,000 ft, with the subject sitting, and not until the sixth minute was it certain that the ‘descent’ could be completed.

The subject [Pask] made two attempts to raise himself in the harness by pulling on the parachute risers during 1 1/8 to 1 ½ mins. These attempts he could not remember afterwards. At 1 ½ minutes., the subject became limp and relaxed, the head falling forward, but although it must have been merely a matter of chance, it was not thought that laryngeal or pharyngeal obstruction actually developed, although vigorous inspiratory efforts were made.

Sweating was very profuse and liquid sweat fell from the forehead and formed a noticeable pool on the floor. Muscular twitching of the left arm was seen between 5th and 9th minutes. The pulse was not rapid – indeed a good deal slower than in previous ‘descents’ with this subject, but between 2nd and 6th minutes it was recorded as very feeble.

[the experimental record of one of Pask’s ‘descents’]

The upshot of all this was that Pask demonstrated that 30,000 feet was the highest survivable altitude to bail out without supplemental oxygen. I somehow doubt that such experiments would get past a modern day Ethics committee!

Post War Years

Pask’s bravery was recognised with award of the OBE (Military Division) in 1944. His meticulous approach to experimentation ensured the success of his 1947 thesis, although public publication of his wartime research was delayed until 1957, no doubt for both secrecy reasons and also in view of the justifiable outrage concerning similar experimentation on non-willing volunteers by the Nazi’s at Dachau.

It is a tragedy of man’s inhumanity to man that the Luftwaffe used human prisoners in these experiments. An account of the abhorrent work of Nazi Dr Sigmund Rascher is here. A disturbing thought is whether the data from these brutal crimes could be used subsequently – an issue explored in the NEJM. Ironically Rascher was executed on the orders of Himmler, in part for falsifying his data.

Recognising the folly of ongoing human self-experimentation, Pask was instrumental in developing Sierra Sam, the forerunner of modern crash test dummies. This proved a safer method for testing modern lifejackets than anaesthetising Gar Pask!

Pask died in 1966, age 54 – no doubt the toll of a lifelong smoking habit and the high likelihood of aspiration during the ‘flotation tank trials’ contributed to his early demise.

HUET & Lessons for Medicine

I was a little apprehensive about undergoing HUET training, mostly due to some gentle winding up by the likes of Minh le Cong in Queensland & some of the GSA-HEMS mob. Comments about eliciting cremasteric reflexes, sinus douching and so on seemed to be setting the scene – made worse as undertaking HUET in the middle of Adelaide winter.

Augsburg
“Back in the day” – a young Dr Tim posing whilst C1 slalom training – Augsburg, Germany

Actually, I don’t know why I was concerned about being dunked. ‘Back in the day’ I was a keen (and expert) whitewater canoeist. I rose through the ranks in both kayak and canadian classes, competing regularly at premier level in slalom events in the UK and representing my country overseas. Being flipped over in the dark whilst training in the ice cold waters of the Thames weirs or on the grade IV rapids of Scottish rivers was no problem.

Competing at that level of performance, the difference between boat-body-blade was indiscernible, with movements practiced and fluid such that one could quickly (<1 second) roll up from an inverted position with barely an interruption to forward paddling movement.

Augsburg2
Boat-Body-Blade – it’s a bit like Arm-Laryngoscope-Epiglottis

But that was a long time ago. Being stuck inside a metal airframe and dunked upside down is completely different. And unlike a low volume carbon-kevlar canoe, there’s no element of control when a helicopter ditches…

Training took place at the heated (27 degrees, thank you) pool at the Adelaide Dive Centre, under the expert guidance of the team from RHO aviation.

Why bother with HUET?

Brian Burns of Sydney HEMS tweeted this slide today from the concordant HUET exercise in Sydney, demonstrating why it is vital that anyone being transported by a helicopter platform knows what to do in the event of ditching in water.

Whilst it is possible to perform a controlled ditch on water, this will be subject to water conditions, aircraft performance and so on. Some helicopters have floats – but helicopters are inherently top heavy and are highly likely to invert. Or be attacked by sharks as in this clip below from Jaws 2 :

That said, helicopter transfer is reasonably safe. The most pertinent reference that I could find dates back almost 10 years and is from Dave Cooksley and (then registrar) Jim Holland when in Townsville, both nice FACEM chaps. However problems can occur and it makes sense to be prepared. Helicopter Underwater Escape Training (HUET) is designed to improve the chances of surviving a ditching episode.

As can be seen from the footage below, an uncontrolled ditch in water poses risks of disorientation, impact with unsecured equipment and debris from the impact. Add to this the confusing elements of inversion, cold water and poor/zero visibility, and it is easy to see why occupants can become disorientated and fail to survive. Add to this the myriad of different harness & door release mechanisms (over 35 of the latter, with no industry-standard!). HUET training is designed to increase chances of survival in an unlikely emergency.

So what did we learn?

The facilitators from RHO aviation were really good, working through educational material in a solid, stepwise manner with a clear goal (lessons there for meducationalists). They emphasised the importance of a pre-flight safety brief :

  • seat belts
  • loose items (secured)
  • lifejackets
  • identifiying primary & secondary exits, with reference points

It is no secret that I am a fan of checklists in a crisis – when there is time. But the regular performance of a safety brief reinforces safety, mitigates against complacency and is something that I try to instil into the resus bay of my local hospital when awaiting a patient – checkling O2, suction, confirming presence of airway and crash carts, setting up vent and anticipating likely clinical needs…as well as backup plans. Cliff Reid has talked about the value of having a resus room safety officer….perhaps it’s not such a bad idea, especially in EDs where the resus is performed by a flash team (members who may never have worked together, or are used to another ED’s equipment/procedures). Minh le Cong (who never sleeps) has proposed a pre-ED RSI safety brief, albeit tongue-in-cheek.

Once the aircraft inverts, the importance of WAITING for cessation of violent movement was emphasised (to reduce risk of disorientation, injury), then calm performance of a well-rehearsed sequence :

  • orientate (use one hand to anchor as a fixed reference eg: underside of seat, with inboard hand)
  • locate (primary exit, use body movement eg knee or shoulder to locate door, then use outboard hand to locate exit release)
  • release (once exit open, keep outboard hand fixed on frame and then release inboard hand to undo safety harness)
  • vacate (use a low profile, pull inboard hand to join outboard hand at exit & pull head through – body will follow)
  • inflate (clear the surface of debris and inflate lifejacket if safe & appropriate to do so)

It was certainly easiest to perform this drill with eyes shut, avoiding the potential added disorientation of visual cues whilst inverted. Obviously an emergency ditching is a high stress environment – there will be a catecholamine surge and removing factors likely to add to panic is sensible

What’s the parallel in resus? There are probably a few. I was immediately reminded of similarity with CICO crisis training. I’ve had the misfortune of doing a few of these in real life, and have learned (by hard experience) to perform surgical airways as a tactile procedure (scalpel-finger-[bougie]-tube). But body mechanics are important in other things we do – threading a catheter onto a seldinger wire (use palmar aspect of both wrists to form a stable bridge, giving fine motor control) or effective laryngoscopy (understanding different mechanics of Mac 3 vs 4, elbow and wrist position to maximise force – a plug here for Rich Levitan’s airway course which certainly helped my airway technique).

Here’s a demo of the HUET in action – experimental test crash dummy Dr Francis Lockie uses his secondary exit, as the primary exit is blocked.

In summary

Despite the ‘wind up’ about HUET, I thought it was a well run course, delivered exactly what it was supposed to and has given a structure to dealing with a ditching crisis.

Could such lessons be applied to medicine? Absolutely – building muscle memory, relying on simple drills and regular sim are key.

Sabbatical with Retrieval

It’s pretty obvious that I see the benefit of FOAMed for rural doctors as in the ability to ensure rapid knowledge translation, particularly in fast-moving fields such as emergency medicine. Although the work of rural docs encompasses predominantly primary care, our work intersects with emergency medicine when on call for out small rural hospitals…and of course some practice obstetrics, anaesthetics or surgery.

I am keen to apply best evidence to care of the critical patient; caring for these patients is something that rural doctors do relatively infrequently and it can be hard to maintain both skills and knowledge. There are some rural doctors with high end skills (particularly those who practice procedural medicine) – but such work may be very much out of the comfort zone for some doctors working in the country.

It’s very easy to fall into the trap of criticising patient management by others – we’ve all seen (or worse still, been part of) the ‘ICU-puts-down-ED-management-which-puts-down -primary-care-failings‘. It’s easy tribalism. I’ve blogged about this before in the “Be a ZERO not a HERO” post.

Whilst there is no shortage of muppetry across disciplines, I am more interested in ways to improve delivery of care in rural Australia, despite the problems of regular skills maintenance, relative infrequency, staffing, equipment and so on. Less criticism and tribalism, more solutions…

FOAMed is one way of helping to rural doctors to avoid being the ‘weak link’ in both EM as well as other areas of medicine. Having excellent support (iCCNet, medSTAR retrieval etc) is essential – but I think it behoves rural docs to avoid a therapeutic vacuum, even whilst awaiting the retrieval ‘cavalry’ to arrive. To whit : doing the simple things, well. Training for the occasional emergency. Using appropriate cognitive aids (action cards, checklists etc). Understanding the value of regular in situ sim-training with all players (doctors, nurses, admin volunteer ambulance officers etc) involved. Critical illness may be infrequent – all the better to be prepared.

Time to learn from the experts…

With this in mind, I am taking 6 months off to work as a retrieval clinician.  MedSTAR, South Australia’s retrieval service have very kindly offered this opportunity and I look forward to soaking up as much knowledge and skills as I can in the time.

Whilst it’s a bit of a jolt (and pay cut!) to move from my own private practice as a rural doctor to a salaried role, I reckon the experience gained will be worth it…

Learning from a high-performance organisation like medSTAR should have flow on benefits to delivery of care in the bush. So I need to get out and learn more…and there is no doubt in my mind that I have lots to learn from the experts in delivering critical care to rural South Australians.

In keeping with SA Health’s social media policy, I won’t be describing any of the cases I am involved with during this time (not that I’d discuss any case on this site, other than ‘hypotheticals’ for education purposes)

There may be an occasional sporadic post on clinical topics of interest to rural clinicians, but I do not expect to post much over the next six months. Ditto use of Twitter under the @KangarooBeach handle, unless appropirate.

So … if you see me in your ED (whether rural or metro) please take time to say “G’day”…

Meanwhile I’ve got HUET training to look forward to….

Snake, Snake, Snake!

No, not a rant about the use of pulmonary artery catheters…was out walking recently & came across this fellow.

OLYMPUS DIGITAL CAMERA

As it’s winter, the snakes come out onto road surfaces to warm up. This is a tiger snake – Kangaroo Island has two snakes, the tiger and the pygmy copperhead. KI tiger snakes don’t have the usual tiger stripes, being black to help absorb heat quicker. As is common with island speciation, the tiger snakes here are larger and more venomous that their mainland counterparts. You can see the ‘hood’ on this fellow as he makes himself appear more threatening.

We don’t see that many snake envenomations locally…the vet sees more, as dogs and snakes don’t mix. Generally snakes will avoid humans…although in the colder months I take especial care when collecting logs from the woodpile, as snakes like to rest there. Come summer, they are generally more active at night – hunting mice and frogs – and occasionally engaging in fights-to-the-death with local Rosenberg’s goanna.

It’s worth thinking about how YOU are going to manage a snake bite in your community – both from immediate first aid (pressure immobilisation, keep still) through to assessment (was this a true envenomation, a ‘dry bite’ or even a ‘stick bite’?) as well as use of snake-venom detection kit to aid decision-making as to which anti-venin to use (clue – if it’s a tiger snake or copperhead, use tiger snake antivenin!) and subsequent resuscitation.

Few quick Qs :

  • who is most likely to get envenomated by snakes?
  • how do you apply pressure-immobilisation?
  • how do determine envenomation or not in a rural setting?
  • how to use a venom-detection kit? to guide choice of antivenin?
  • are there any pitfalls in resuscitation of the snake bite victim?

Rural docs coming along to the RDASA Education Event Aug 8-9th at Wirrina Cove, South Australia will get a chance to quiz Prof Julian White on this topic. I’d recommend the CSL Antivenom Handbook, although I am not at all convinced about counting anal scales in the middle of a resus!

Might also be asking Prof White for his views on use of redback antivenom!

Eminence vs evidence-based medicine? Great review here from AdelaideEmergencyPhysicians.

 

The More I Know, The Less Certain I Am

I’ve recently had cause to re-examine Dale Edgar’s ‘Cone of Experience‘. Like that fabulous educator from iTeachEM, Rob Rogers (@EM_Educator), this concept seems intuitive and demonstrates nicely the benefit of learning via different formats. I use it in talks to explore different learning styles.

Screen Shot 2014-07-24 at 3.28.00 pm

Except it’s bunk. Dale never ascribed percentages to the retention rate for each different mode of learning; rather the ‘cone of experience’ demonstrates the varying abstraction potential for each learning mode. Understanding that Dale’s model was centred around understanding the concretness of different material, not retention rates.

Why is this important? Because it’s not uncommon in medicine to come across the view that “there is only one correct way to do X

When I was a junior, following such rules made sense – they reduced the burden of having to ‘think’ too hard … and when such rules were imposed from a higher authority (invariably a gruff Consultant), failure to comply risked raising their ire! Of course it’s not just lack of years or having a steep authority gradient that encourages sticking to such rules. As humans we tend to seek the comfort of familiarity and our own experience when making decisions – hence the “I’ve always done it this way…” or “Textbook X (authored by eminent expert Y) tells us to do it this way, so I’m sticking with that…” or even the “The teaching is to do procedure X this way – anything else is negligent” conundrums.

Nowadays when someone asks me how to do something, I seem to find myself pausing more and more as I reflect on previous experience. No longer do I say “Chest drains? They’re easy, let me show you how” – instead I pause “Well…it can be difficult…let’s talk about it, then I’ll help & guide you through one” as I recall not the vast majority of easy ones, but the difficult cases, the errors made, the complications…and am keen to relay this tacit experience bro e through mistakes to my colleague.

Some recent debates on social media have been relevant. Over on doctors.net.ukfora, we’ve had examples of :

– experienced clinicians ‘told off’ by physios for eliciting lower limb reflexes in a seated patient “the ONLY way to do reflexes is with patient laying down”

– anaesthetists laying into emergency physicians over options for safe sedation of the haemodynamically compromised patient in VT (with the usual cliched ‘needs RSI‘, through ‘mustn’t use ketamine because of strain on heart‘ through to ‘just zap them and apologise‘). Kudos to Cliff Reid & Ed Valentine for keeping their cool in that debate!

Meanwhile there’s been a useful Twitter and Google+ exchange on dogma around use of femoral traction devices (FTDs) for splinting of femoral fractures in the presence of a pelvic fracture

There are plenty of other discussions that crop up – cricoid force, checklists for crisis, thrombolysis in stroke, acceptable modifications to RSI etc etc

In all of these discussions, it’s not uncommon to see people looking for “rules”. In the recent examples,

– physio wanted a rule that all lower limb reflexes are elicited in supine patient

– anaes colleagues wanted to use propofol RSI for the patient in VT and berated use of ketamine

– traditional teaching is to avoid use of FTD in presence or suspected presence of pelvic fracture; some paramedics were lookign for guidance on rules whether to use a FTD or not. Wise words from experienced paramedic/retrieval practitioner Dave Tingey “clinical judgement is the key – especially where there is little or no evidence” – he emphasised focussing on patient outcome, not rules for a process!

FOAMed – tacit knowledge sharing with global community

People ask me why I use social media for learning. For me the attraction of FOAMed is that it addresses the issues where there is clinical uncertainty. If you are looking for absolutes (as when learning the craft of medicine or to pass exams) then stick to the textbook teachings. If you are looking to test yourself and continue to explore the expanding frontiers of knowledge, then use FOAMed. It opens up the world of #dogmalysis and enables corridor conversations with clinicians worldwide. Some of what you encounter is bunk…some is golden. The trick is to filter, engage, question and unlike politicians, don’t stick to one party line.

Even if “the more you know, the less certain you are!”

Rural Prehospital Care Survey

The phrase “critical illness does not respect geography” is often quoted, reflecting the fact that mishap can affect anyone, anytime, anywhere.

We are lucky to have excellent tertiary level emergency departments & intensive care units in Australia to deliver specialist care. Developments such as FOAMed help to narrow the knowledge-translation gap from publication to practice. Furthermore, the widespread dissemination of information via asynchronous learning (such as slide sets, podcasts, videos hosted on websites, or corridor conversations via twitter) means that geographical isolation alone is no excuse for the rural clinician to be the ‘weak link’ in provision of care.

But Australia is a vast continent – making the provision of immediate care problematic in the more rural & remote areas. Certainly we have excellent prehospital & retrieval services; but although road and rotary-wing responses are rapid, they are limited in timely response when distances are large. The sheer size of Australia means that even responses by fixed-wing aircraft may take hours to arrive. My job as a rural doctor is to deal with ‘anything & everything’. We offer primary care as a core skill, along with a smattering of emergency care. Many rural doctors have advanced skills in obstetrics, anaesthetics and surgery. ACRRM considers involvement in local disasters and emergencies as part of the rural doctor primary curriculum skill set. It makes sense that the doctors with ongoing exposure to resuscitation & airway management (typically rural GP-anaesthetists) are called when there is a rural emergency.

But is the involvement of rural doctors a good thing?

Perhaps not. The experts in delivery of prehospital care are those with specific training and resources – classically State-based ambulance services, supported by services with retrieval expertise (eg: RFDS, CareFlight, HEMS, medSTAR etc). As a hypothetical, I think that if I was involved in a vehicle rollover, I would want to be looked after by the experts, not an ‘enthusiastic amateur’ GP.

So there is the dilemma. The further from a tertiary centre, the longer it will take for retrieval services to arrive. The more remote you are, the more likely that ambulance responders will be unpaid volunteers, not career intensive-care level paramedics…and the more likely that local clinicians will need to be involved in care.

A 2012 survey of rural GP-anaesthetists surprised me; just under 60% of responders stated that they had been involved in some form of pre-hospital incident in the previous 12 months. However of those responding, very few had training in prehospital care, very few had equipment to deliver care and most were tasked to the scene in an ad hoc manner (no formal call out criteria). As a consequence, the quality of responder on scene is highly variable – you may get a senior rural doctor with regular exposure to advanced airway management…or you may get a relatively inexperienced GP with very little emergency experience, let alone skills useful to prehospital care.

I can certainly empathise with the notion of ‘no room for enthusiastic amateurs, leave it to the experts’. Yet interestingly, the request for rural clinicians to attend such incidents came from the experts in prehospital care – ambulance comms and retrieval coordinators, usually because of the severity of the incident and dearth of readily available resources.

You can watch a summary of the issue here from the smacc2013 conference.

Role of the rural clinician in prehospital care?

There are several systems worldwide aimed to deliver immediate care when and where needed.

At a basic level, community first responder schemes such as PulsePoint and GoodSAM (smartphone activated medics) allow crowd-sourced delivery of basic life support to patients even before ambulance services arrive. Responders are typically volunteers, with senior first aid, paramedic, nursing or medical qualifications who are prepared to respond if an incident (cardiac arrest, impact brain apnoea) happens in the immediate vicinity. Activation is via the GPS in smartphones.

At the top end of prehospital care are ambulance and retrieval services, with trained teams, dedicated equipment and service delivery aimed solely at best practice.

Somewhere in-between are systems integrate appropriately-trained volunteers to support ambulance services and deliver care before retrieval services arrive. Examples include the UK BASICS (British Association of Immediate Care Schemes) and NZ’s PRIME (Primary Response in Medical Emergencies). Responders are typically nurse or doctor, with high-level resuscitation skills (typically rural GP, emergency physician, intensivist). They are tasked under defined activation criteria and are trained, equipped and audited. UK BASICS are generally unpaid and work is taken on additional to NHS duties; PRIME is paid.

South Australia has an embryonic scheme, RERN (Rural Emergency Responder Network), utilising experienced rural doctors to respond to prehospital incidents in their community, only when attendance of a doctor will ‘value add’. This can be useful where local ambulance responders are volunteers, when local expertise (career paramedic) resources are overwhelmed and/or when arrival of specialist retrieval services will take some time. As such RERN responders are equipped with standard prehospital equipment, undertake ongoing training and case audit. Participation (and indeed attendance) is voluntary; remuneration is on a fee-for-service basis. You can download a presentation from Dr Peter Joyner here or watch a youtube video from CountryHealthSA featuring medSTAR’s Bill Griggs on the RERN model here.

Some other States have standardised Hospital ‘emergency bags’ for use in a disaster (such as Western Australia’s Parry Pack); yet no formal training for their use or clinician involvement in such incidents. NSW is leading the way with not just standardised equipment bags but also open-access training for rural clinicians.

So is the BASICS-PRIME-RERN model one which could be applied elsewhere in rural Australia? I think so, but only in certain locations and in certain circumstances. Clearly the ethos of rural doctors responding to local emergencies is congruent with that of ACRRM. Historically rural doctors were called as default; this has (sensibly in my opinion) been superseded by delivery of specialist care via ambulance or retrieval services, offering a far higher level of care.  Yet rural doctors are still being called, often by the same experts!

To continue with ad hoc responses by whichever local GP is available is nonsensical, especially without appropriate training and equipment. Equally to ignore the fact that many rural doctors have ongoing experience in initial emergency management and airway skills via work in local hospital ED and Theatre may deny rural patients access to lifesaving skills. Of course one has to be mindful that experience in the Operating Theatre or ED does not translate to the roadside and the experts remain paramedics and retrievalists…when available.

Other countries recognise the fact that there is a therapeutic vacuum between initial incident and arrival of retrieval services; that geographically-constrained countries such as the UK and NZ have these systems and yet Australia does not is puzzling, especially when considering the tyranny of distance and unique skill set of Australian rural clinicians.

Take the Survey

What do you think? The link below is to a survey which will go to rural doctors registered with ACRRM and the RDAA; however it would be good to get feedback from a wider cohort – from established retrievalists, from paramedics, from nurses – in fact, ANYONE who is involved in critical care.

CLICK HERE TO TAKE THE RURAL PREHOSPITAL SURVEY (5-10 MINS)

As Karel Habig said at smaccc2013: “Good critical care is good critical care, wherever you are.”

I think it would be good to ensure systems to deliver appropriate care where gaps exist. But it has to be something that rural doctors are prepared to engage in – and has to be embraced by other services.

To put it bluntly, either we include rural clinicians in the system or we do not. The latter may be ideal from a metrocentric perspective, insistent on gold-standard specialist-lead prehospital care. This is the service I would want as a rural patient! But a pragmatic approach recognises that there will be temporary service gaps due to distance or lack of available personnel and that plugging these gaps already involves rural clinicians – yet in an unstructured, unequipped and untrained manner.

I reckon that we can and should do better than that in Australia.

PROS

  • recognise that rural clinicians are already being called to attend prehospital incidents; ensure that such responses are by trained/equipped/audited responders, not ad hoc
  • utilise those rural clinicians with ongoing experience in trauma, emergency medicine and anaesthesia, who maintain skills through regular exposure in hopsital ED and Theatre
  • task rural clinicians only when their presence will ‘value add’ to the prehospital scene eg: IV access, ketamine for extrication, needle/finger/tube thoracostomy, prehospital airway management
  • establishment of State or Nationwide cadre of rural responders may provide extra resilience in case of disaster eg: earthquake, bushfire, flooding [and may be acceptable to existing State-based agencies]

CONS

  • prehospital environment is very different to hospital; requires skills best delivered by ambulance and specialist retrieval services, not amateurs
  • presence of a rural clinician may not value add (local GP arriving in boardshorts and thongs with no kit/training is worse than useless), detract from delivery of care by local resources
  • potentially high cost to equip and activate responders (PPE, prehospital kit, pagers etc)
  • relative infrequency of incidents carries risk of skill fade

Really interested in perspective from others.
