I typed this up as a reply to the ACLS algorythm and drug thread, but after looking it over felt it deserved it's own thread.

It poses no questions, it is more of a statement, but use it how you will.

I think that the major problems with resuscitative science are:

We keep constantly trying to refine what we are doing. Which implies that it does work and therefore just needs to be tweaked a little each time. Which is why some practices that never seem to show benefit despite decades and $ millions if not billions, keep getting wasted on (let me be generous) research.

The fact is, when some of these ideas and concepts were thought up, whole branches of science like molecular biology either didn't exist or were in their infancy.

The treatments were based on expert opinion, because that's all there was. The research is not validating much of it. (no, I am not going to try to link every research article or study I have ever read about it, have some initiative.)

However, like most things that plague EMS treatments today, the expert opinion of yesterday is all but carved in stone, and therefore has been repeated so much it is accepted as fact.

But today's experts who have infinately more understanding and resources are either

a. discounted becase "expert opinion is the lowest form of research." True, it is not very good research or evidence, but it is not given enough weight.

b.There exists the demand to prove beyond all doubt through "research" which ethically and legally cannot be performed theories formed with today's understanding.

So in essence the expert of yesterday has become all powerful when today's experts are all but ignored.

Another problem is that the most educated and experienced resuscitation experts at least in the US, rarely have any contact, much less input on EMS practices or procedures.

Part of it is drawing lines in the sand, but let's face it, the anesthesia intensivists resuscitate more people way more often than EMs do, simply because of the volume of those who need resuscitation in both surgery and the ICU.

I am not picking on EM or anyone else, but the barriers from all sides have to come down if there is going to be progress. All of the Anesthesia docs I know actually ridicule my interest in EMS, and tell me to quit wasting my time. EM needs to realize they do need input from people outside EM. It is almost as bad as field providers telling hospital staff they don't know what it is like outside, as if the science changes. But in fairness, Anesthesia also needs to release some of the tools and procedures they hold as exclusive which interferes with the advancement of resuscitation elsewhere. (like in an ambulance)

If we are to dismiss today's experts as unproven, then we must also dismiss yesterday's experts equally. It seems like there is a barrier to progress we have erected and continue to defend.

When you are in trouble, and your life on the line, to save it, it may take the smartest person you can summon.

In all likelyhood it logistically cannot be a physician. So in order to have people like paramedics fill in, they are going to have to become true experts in the art and science of resuscitative medicine.

Simply knowing the procedures and a basic algorythm isn't going to do. Simpliefied concepts will not work either.

In order to be successful and not just a "feel good" service because they try, EMS providers are going to have to stop clinging to partial understanding. Especially the parts they themselves determine to be important. (As if they know)

They are going to have to learn things like molecular biology, biochemistry, cell biology, etc.

Now I know some say that those mean little in the realtime world. I call BS. I have been taught to use that in my decisions. I do use that in every medical decision I make everyday. If it can be taught to me it can be taught to others.

Here is something interesting to ponder:

The original EMS providers were taught specifically by physicians. There were considerably more demands on them. There was more material covered and more proficency required.

It wasn't until EMS started "training it's trainers" that the downhill slide began. It has evolved into the largely unknowing, teaching those who know nothing.

Well, the educational thread has been beaten to death. So here it is.

The very booklist you need to start becoming a real expert of resuscitative medicine. Forget those nursing manuals, and EMS guides that "boil it down."

Here is what you need, it is applicable to every patient you see. If you don't understand how, the fault is yours, not the material.

Biology, Raven
General chemistry, Hill
Organic Chemistry, Wade
Molecular Biology of the Cell, Alberts
Biochemistry, Garret and Grisham
Physiology, Guyton
Robins Pathological Basis of Disease, Kumar
The developing Human, Moore
Fundamantal Neuroscience, Oswald
Pharmacological basis of theraputics, Goodman and Gillman
Principles of Internal Medicine, Harrison (as if there was another)
(for the ped's folks add Textbook of Pediatrics, Nelson)
Miller's Anesthesia, Miller

(no this is not the booklist required for my degree, infact it is only about 1/2)

But if you truly want to join the major leagues of resuscitation instead of the little league of algorythms and studies, this is in my opinion, where you need to start. The only thing stopping you is your efforts. (and of course your wallet)
 
Have you checked out EMCrit and EMRapCC blogs/podcasts?



Dang Vene, you keep on giving me strange fantasies of medical school. *must resist the urge to change careers*...

No, I focus more on CC surg and anesthesia, usually if it says "EM" I just pass it by or don't even know about it.

Besides, most of my friends are EMs so I get a lot of that perspective in my daily life. It is why I think they need to be less exclusive.

I have only known 1 nurse to become a physician. A damn fine one he is at that.

These guys are pretty dedicated to providing Critical Care in Emergency Departments. I'm sure you have a list of resources you are tapping, but these are worthwhile in that they are 20 -50 minute lectures. Pretty interesting

Awesome post, my quest to assemble this list begins now. Well, I might watch the crow and fall asleep for a few hours first:ph34r:

But seriously thanks
 
Here's to WAR!

The innovations people pay attention to are the ones found during War. There, it appears lives are actually saved and new innovations actually happen. Kind of like, if it works in War it's passed the Acid Test!

Take the tourniquet for example. Wait a minute, wasn't that debunked? Oh, I guess it's coming back into favor again.

THEN, in the Civilian world, it was PROVEN it wuzn't so hot. But NOW, in Afghanistan, it's the cat's meow!

But the whole mess pretty much started with patching soldiers up so they could fight again; here's a cool article on it all!

Were it not for Viet Nam, there would NOT have been paramedics because wireless walkie-talkies were what made us "the eyes and hands of the Doctor" by virtue of the fact we had his ear!

Besides, as you can see by the quote leading off the article,

“ It is appropriate that experience during unavoidable ‘epidemics of
trauma’ be exploited in improving our national capability to provide
better surgical and medical care for our citizens.” Surgeon Neel,
Colonel, Medical Corps, U.S. Army1

...this kinda gives War a humanitarian spin, doesn't it?

It's been getting such a bad rap lately!

You couldn't pay me to go to medical school. Personally, I'm looking forward to the day I don't have to treat patients to maintain my standard of living. LOL

It was never proven ineffective. It was simply a victim of bad press, junk science, superstition and improper use. Here's an actual article on the subject: http://www.wjes.org/content/pdf/1749-7922-2-28.pdf

Actually I do a presentation on the effects of war on medicine, and for a small fee I am always willing to travel to your local to give it.

It is a bit more indepth, which is not the purpose of this thread really, but just to address the TK.

It wasn't that the TK was ever disproved for effectiveness, it was remove from the civilian world because the types of wounds and proximity to the hospital made it a treatment that caused more problems than it solved.

It was the advances in vascular surgery that turned that risk/benefit around.

It is just like with things like quick clot. In the military the chances of a penetrating truncal wound is greater in battle conditions. Do you see them in the civilian world? Sure several times a day in some places, but how many of them are decided by field hemostasis? Few.

The damage caused by an uncomplicated GSW like a low caliber through and through doesn't always mean intervention outside of bandage wait and see.

The medical advances have come from rather inhumane experimentation or "refugee" conditions, which is too much for me too explain in the characters here, but it is basically stressors to living in habitats that do not support human populations in an area as an effect of war.

It is also very important to consider the system for medical care in place by Armies like the US or Israel is considerably different in both capability and money spent through the continuum of care. You TK a soldier's wound in a nation without US or equal support, and the loss of the distal wound will be no different than it was 100 years ago.

Likewise. In fact, cover my travel expenses and I'll come.

made it a treatment that caused more problems than it solved.

Actually if you look at the data on the rate of complications associated with tourniquet use, it's so minimal as to be laughable. The most common issue is that it's not put on tight enough. The "it caused more problems than it solved" myth came out of its use (or lack of use) in prolonged military medical settings where evacuation to definitive care took hours or days. The American Civil War and the Crimean War are two great examples of this. Even different battles during the Civil War had vastly different data on the utility of tourniquets simply based on the differing delays associated with casualty evacuation (i.e. First and Second Battles of Bull Run).

I would be interested in seeing how that data came about and when.

But I would readily concede that a tourniquet placed for less than 10 minutes, which would be most urban transport times wold have absolutely no ill effect at all given the compensatory mechanisms of skeletal muscle.

Not surprising since I would bet in addition to to the loss of limb the most likely sequele would be renal damage, which was only minimally treatable at the time.

See the article I cited as it is a pretty comprehensive literature review of everything on the topic up to I think 2007 or 2008. If you need copies of some of the references mentioned in there, let me know as I have collected them as well for my presentation on this topic. The Israelis, the orthopedic surgery community and the US Air Force Theater Hospital vascular surgery registry all have tons of data on the frequency of complications.

Even after several hours of no-flow, there seems to be minimal chance of rhabdomyolysis. This is supported by the use of tourniquets in orthopedic surgery for several hours at a time.

I think there might need to be some clarification as to what we are both thinking about because after reading your pdf and the comment about modern orthopedic surgery I don't think we are on the same page.

In the PDF it stated several times of people being anti tk because of potential major complication which seems defined as loss of limb.

It uses as a basis of it's position in combat wounds, which I do not dispute at all.

It does go on to say that there likely can be some nerve damage in those who are comprimised by comorbidity such as diabetes. It also speaks about improper application of a tk as well as the rapid reassessment of non field providers as to the need.

I do not think that this contradicts my position in any way.

Advances in vascular surgery have been responsible for better outcome.
Modern system design has been responsible for reduction of loss.
I am not disputing that at all.

However, the use of tk in a civillian setting and associated complications of nerve damage, as well as an increase in hospital stay or need for extended treatment when a tk did not need to be placed, but was by overzealous providers, because another method of like direct pressure may have worked as well, has not been refuted and as far as I can tell from this paper, not even addressed.

In the recent past when tks were out of favor in EMS, I would think that this level of complication would be a reasonable suspicion as well as preventable by taking the toy out of the hands of those who might use it when it was not indicated, similar to the early use of factor VII in traumatic injury. (though not as dramatic)

In the civillian sector, the over use of device which can cause prolonged hospitalization, rehabilitation, or the need for more advanced and therefore costly treatment is the unacceptable complications I was referring to. Not some dramatic limb loss.

As for the last reply, I really don't think you mean to draw a comparison between potential rhabdomyolysis with the surgical tools and techniques of the American Civil and Crimean wars I quoted you as citing with the surgical tools and techniques of the modern surgical theatre?

When I was doing research for my presentation, I found no significant evidence to support a major risk of complications from its use.

In the civillian sector, the over use of device which can cause prolonged hospitalization, rehabilitation, or the need for more advanced and therefore costly treatment is the unacceptable complications I was referring to. Not some dramatic limb loss.

The issues arise not from improper use but prolonged placement (>8-12 hours) which is not a factor in the civilian world except in third world nations, wilderness environments or extreme situations. The risk of complications- limb related or otherwise is exceptionally small- is pretty much negligible unless you have some other situation where there is already an increased risk of renal failure, nerve damage, etc. The example I use for this is crush syndrome. The risk of renal failure from prolonged hypotension due to blood loss is going to pose a much greater risk. The risk of overuse is so infintessimal that if I recall correctly that it took several years worth of data for the Balad Vascular Registry to get into the double digits for total number of cases with noteworthy complications directly attributable to the tourniquet and most of these were still very minor.

Given that fact, I don't see a major source of concern for overuse in the civilian sector.

As for the last reply, I really don't think you mean to draw a comparison between potential rhabdomyolysis with the surgical tools and techniques of the American Civil and Crimean wars I quoted you as citing with the surgical tools and techniques of the modern surgical theatre?

I was referring to the difference of the modern medical care system where a trauma patient taking more than 2 hours to reach the hospital is going to be a big deal contrasted against the 1850s and 1860s where if they arrived on the same day as they were injured they could count themselves lucky. The surgical care is secondary. The major issue here is really one of transport and access to care. For extremity trauma, control of hemorrhage has not changed significantly since the late part of the 19th century. What has changed is the ability to salvage limbs that would have been amputated back then. For the sake of this argument, whether the limb is salvaged or the limb is amputated is really a moot point.
 
When I was doing research for my presentation, I found no significant evidence to support a major risk of complications from its use.

I think because of the amount of time TKs were not in favor in the civilian world, there is not likely to be such a study to be found.

In my mind it stands to reason, if they haven't been common in the better part of a decade, how much data could there be?

Because there is no data existing doesn't make something less true or less likely. How long had there be no data and even now inconclusive data on most EMS practices. Hell even with data you can't get EMS people to stop doing crazy things like LSBing every "mechanism" injury, or high flow o2, or doing compressions in moving vehicles.

Maybe you just have more faith in the system than I do.

The risk of complications- limb related or otherwise is exceptionally small- is pretty much negligible unless you have some other situation where there is already an increased risk of renal failure, nerve damage, etc.

But most of the modern civilian population does have risk factors. Everything from alcoholism to medications, congenital defects, etc. In the Western world 1 in 5 people have HTN. (according to some renal association I had to sit through a lecture about recently) Hyperlipidemia, you name it. The percentage of "healthy people" in the general population with an isolated traumatic injury is nowhere near comparable with either prior generations or current military persons.

The example I use for this is crush syndrome. The risk of renal failure from prolonged hypotension due to blood loss is going to pose a much greater risk.

I think it depends on the mechanism, most of the patients I have seen who exhibit crush syndrome are elderly patients who fall, manage to get in a squating position and then get stuck cutting off circulation to their lower extremities. Actually I have seen it so often, I am starting to accurately predict the outcomes in cases as well as being rather skilled in removing necrotic tissue at speed.

They have no blood loss at all.

Perhaps second to that in my experience for rhabdo are victims of severe beatings.


The risk of overuse is so infintessimal that if I recall correctly that it took several years worth of data for the Balad Vascular Registry to get into the double digits for total number of cases with noteworthy complications directly attributable to the tourniquet and most of these were still very minor.

I think with the decline of incidence of major trauma in the modern world, precipitating a lack of comfort with it among EMS providers, as well as the reintroduction of widespread TK use, and agents such as chemical dressings, the complications are going to increase. However, like I said, people are not going to start losing limbs, but might be spending some extra time and tests in the hospital. Maybe in another 10 years there might be some data on it, but I don't know if anyone outside the military is even studying it, or under what circumstances?

Given that fact, I don't see a major source of concern for overuse in the civilian sector.

With the "be prepared" ricky rescue types who all think they are the latest in tactical medic, the lack of familiarity with major injuries, and the decreasing depth of EMS educaton, with my most sincerest respects, I cannot come to the same conclusion.

Then why is the rate of tourniquet use related complications in the orthopedic community so low despite the tourniquets being on for much longer and at often much higher pressures than you see with field tourniquets?

Even if you have Ricky Rescue, unless he encounters a patient and goes Buffalo Bill from Silence of the Lambs on the patient and makes them rub the lotion in their skin for half a day or more before taking them to the hospital, the chance of complications is negligible.

BTW, you do realize I do my presentation (about 60-75 minutes) with a tourniquet around my left arm right?

However, like I said, people are not going to start losing limbs, but might be spending some extra time and tests in the hospital.

Any evidence to back this up or are you just theorizing?

Maybe you just have more faith in the system than I do.

LOL You do remember who you are talking to right? I don't have faith in anything but what I can prove and given the data out there- both from the trauma and the elective surgery communities- the best evidence is that tourniquets pose a minimal risk in patients even with multiple risk factors.

Off hand, pre and post surgical care, but I will check out the specifics of it. I have some ortho time coming up.

Are you tempting fate?

There is an EZ IO sales guy who drills himself to prove it doesn't hurt and some crazy docs in Indian just did a surgery without anesthesia on one of themselves to prove it could be done.

Good idea?

a decision you have to make on your own. But I would be more convinced if you put the TK on some 70 year old lady or a 2 year old kid, looked for complications or asked them what they thought about it after. :)


Any evidence to back this up or are you just theorizing?.

Theorizing.

But do you honestly see somebody with an active bleed with a TK on, come into the ED, get sewn up and DCed without some kind of attempt at confirmation that no complications are likely or deficits exist?

I doubt anyone in the US is going to make that determination from clinical exam, and the second you call for a neuro, vascular, or hand consult, that is going to generate some charges. More still if they are admitted for obs or serial blood/urine or imaging is ordered.

If the injury was serious enough to warrent it, I could see, but I just can't see deciding the TK was overkill pulling it and a quick wound fix and DCing the pt based on clinical exam being the norm in the US.

LOL You do remember who you are talking to right? I don't have faith in anything but what I can prove and given the data out there- both from the trauma and the elective surgery communities- the best evidence is that tourniquets pose a minimal risk in patients even with multiple risk factors.

Somebody with much more confidence in the data gathering process than me :)

Happens frequently in combat settings. Clinical examination is sufficient.

Just because people practice defensive medicine out of habit does not mean that there is an actual significant risk.
