Hi,

In a moment of reflection I wondered back to a time when “suspension trauma” was quite a popular topic. Not so now, so had a quick search on the forums and the last time it appears to have raised its head was in 2009…..

Now, I recall at the time there was a lot of “noise” around it which the medical profession rejected – my own Occ Health Doctor was adamant there was nothing in the medical literature to support the theory.

So, my question, was it just a bit of a red herring, was it a clever PPE and rescue sales pitch, was it just bad science or has anything come to light since?

Hopefully this will not drift into a general rescue at height thing but anyway, thoughts please,

Jim

A little conflicting info regarding first aid treatment, but the issue is genuine it think.

RR708 from HSE (also written 2009, just checked)

Yes, I was about to post the same thing - here's the link:

http://www.hse.gov.uk/research/rrpdf/rr708.pdf


Syncope (pronounce it how you will) is real enough although the incidence in rope access work is really quite unknown - therefore calculation of level of risk etc. is tricky. But the issue is a foreseeable risk. How big a risk (hence your possible red herring post?) is one of the key queries really.

The advice for basic first aid treatment did indeed change with the new RR from HSE.
However, advanced medical treatment remains unchanged.
It depends how strong your clinical governance is for your organisation.

My take is that it was an entirely believable theory, which is why we all were taken in. But on examination there was nothing tangible (scientific evidence) to back it up.

HSE do seem a bit vague on this. All I could find was :-

http://webcommunities.hs...ight/view?objectId=11763

At one point I didn't think they were actually going to answer the question, but they did towards the end.

There is no date on this web page, to gauge if this info is out of date. The seemed to imply it was considered genuine at the time, but as Walker states actual evidence seems a bit thin on the ground.

I think If I were still in that sort of business I would still take it into consideration when doing the emergency planning.

As far as I am aware you should always have two people (one supervising) when using harnesses as after 5 mins some will faint and after about 20 mins their hearts can stop (orthostatic shock).

I wrote my BSc dissertation on this topic in 2004 and at the time there was considerable research into orthostatic shock. I have lost my copy though in a hard drive error :(!

Good emotive topic to resurrect Jim.

I also agree to some clever PPE sales pitch blurb.

I was always sceptical around the ST footloops and the like due to the simple fact the initial data from the Swiss mountaineering and French speleological dudes was based on immobile/unconscious casualties and I've yet to see an unconscious casualty don footloops.

Hi billstrak

This is the misconception. It doesn't effect conscious casualties.
As they can be encouraged to move their legs etc to prevent the venous pooling, and build up of toxins etc. ST straps were a lovely piece of marketing. You get exactly the same results with a 32p length of blue draw cord and a blames hitch knot!! LOL.

Many say it doesn't happen, the original research was flawed as it polled every single IRATA member to see if they had ever been effected. OF COURSE THEY HADNT.
They are all skilled in self rescue, always under the supervision of a level 3, and never work alone. So they would never be in a position to experience this alleged phenomenon.
Very interesting subject though, in which I've done lots of research.
But I am a rope rescue nerd though!!

So concious casualty = low risk, as they can be encouraged to move and clear toxins..
But as first aiders how should we treat unconscious casualty? I always say to follow normal protocol prioritising airway - so recovery?
I can't see how you can not lay them down and leaving them hanging is clearly not good.

The joys of a simple topic made complex...

For a "first aid" response you would be brave to go against the guidelines in the 2009 RR.
So unconscious cas must be layed flat no matter how long they have been suspended.

The more medically advanced can think outside the box if their clinical governance is strong enough.
BUT THIS IS NOT FIRST AID!!

We can apply bilateral tourniquets to prevent washout, so effectively turning off the taps, and then lay the casualty flat to manage airway etc. Tourniquets are stage released in a place of definitive care with monitoring and correct cocktail of drugs to manage it. The same as we would for a crush injury. But for first aid you will have to comply with HSE RR guidance.

Guys,
Thanks for the very thoughtful, considered answers. It was from an idle moment staring out of a window that the question came but the answers are very interesting,
Many Thanks,
Jim

In my opinion, one of the reasons could be lack of objective evidences.. and medical profession is also full of ambiguities , for instance for some people Syncope may happen after 10 minutes and for some in hour depend on physical conditions. (source Safety Management magazine 2008).. lack of cases and lack of reporting could be an issue

Ex Deeps,

I had an article on this published in 2006 by Tenalps publishing, that they picked up from a document I made free to use on the web regarding WAH rescue. The suspension trauma information that everyone was using at the time originally came from America, and as everyone has already stated, there was no published data to back their case up. The HSE had for some time been conducting their own research on suspension syncope, which is much more reliable and relevant. I think the use of language by the USA is a contributing factor in the perception of 'immediacy' when responding to an incident, however with the HSE information this could now be considered to be just 'damned urgent'!!

I think you only have to remember how our cousins from across the pond speak generally i.e. 'Elmer, I have a situation here'. or 'Hi there, would you like me to clean the bugs of the windshield and check under the hood' (translates to 'would you like me to wash your windscreen and check the engine fluid levels under the bonnet').

Simon

Thanks he02..........I think your response was kind of what I was eluding to.

Also, the original research goes a wee bit further back than polling IRATA members......See my original post.

Indeed billstrak,

It goes as far back as the 1800's, and some academics even blame Christ's crucifixion death on the "syndrome"!!

1972 was probably one of the most useful years for research, as Flora & Holzl et al, amongst others produced very relevant data in this year.

It's all very interesting!

It was Hill and Eppinger in 1935 that made the correlation between crucifixion and the syndrome for anyone interested.

...the only thing the HSE guidance reinforced was that you treat the patient not the symptoms...I work a lot in remote/wilderness emergency medicine and have been struggling with the 'hypothetical' situation of harness induced syncope for years...saying that I still teach the theoretical effects...it was discussed as recently as last years Wilderness Medical Society conference at a breakout session I attended...but then that is predominated by Americans and well...they have a certain view of the world that isn't always based on reality...

Thanks for sharing that Phil..........I can see that as a v-good safety related pub quiz question
