The Downsides of Tourniquets

RogueJSKThe Downsides of Tourniquets
As a LE trainer, active shooter response trainer, and TCCC trainer, I've long been a proponent for tourniquets.
In the last two decades, we've seen a 180 degree about-face in how TQs are viewed. Prior to that, tourniquets were seen as an absolute last resort. But after the trauma experience gained in Iraq/Afghanistan, they quickly became a first response to major appendage bleeding, and TQs became standard equipment for each soldier.
That then quickly migrated to the LE world, with TQs becoming standard issue equipment for LEOs too, and TQ training and frequent drills added to the police academy curriculums and refresher trainings.
And it then naturally made it to the civilian world, with TQs becoming standard in everyone's medical kits, SHTF kits, look-cool-on-Instagram plate carrier rigs, etc.
However, even with all their upsides and their lifesaving potential, it's important to remember that TQs do have their downsides, and they can be used improperly.
I ran across this interesting article today, from
https://www.telegraph.co.uk/gl...-amputations-deaths/ :

‘Cult’ of tourniquets causing thousands of unnecessary amputations and deaths in Ukraine, say surgeons
The tourniquet has saved many thousands of lives and limbs in war zones around the world, but misuse of the device is causing huge numbers of excess amputations and deaths in Ukraine, say top military surgeons.
Captain Rom A Stevens, a retired senior US medical navy officer who has served in Iraq, Afghanistan, and East Africa, estimates that of the roughly 100,000 amputations performed on Ukrainian soldiers since Russia’s full-scale invasion in 2022, as many as 75,000 were caused by improper use of tourniquets.
“I’ve seen tourniquets that have been left on for days, often for injuries that could have been stopped by other methods. Then [the patient] has to have their limb amputated because the tissue has died,” Captain Stevens told The Telegraph.
Tourniquets are strong bands used to stop catastrophic bleeding by cutting off blood flow, and are standard issue for most modern armies.
But if left on over two hours, they can cause tissue death, meaning the arm or leg which has the tourniquet on is no longer viable and requires amputation.
The device became standard-issue in the 2000s wars in Iraq and Afghanistan, where rapid air evacuation to military surgical teams was possible in under 60 minutes. If the tourniquet was unnecessary it was removed, and no harm was done.
But in Ukraine, where the skies are infested with drones, injured soldiers are evacuated by land, often far exceeding the safe time window for tourniquet use.
This critical delay has caused tens of thousands of amputations, say experts, many of which were unnecessary because the injuries didn’t require a tourniquet in the first place.
It has also led to a sharp rise in young Ukrainians needing dialysis, said Captain Stevens who has served as a medical volunteer in hospitals in Zaporizhzhiya, Dnipro, and L’viv since the invasion in 2022.
This is because when a tourniquet is removed after being kept on too long, toxins from dead tissue flood the bloodstream, overwhelming the kidneys.
Captain Stevens helped draft the US military guidelines for tourniquet use and now wishes greater emphasis had been placed on assessing when they were needed to stop bleeding.
He fears that their successful use in wars where rapid evacuation was possible has led to a “cult-like” dependence on a tool that should be used much more sparingly.
In Ukraine, it has left “a generation of men traumatised by unnecessary amputations,” he said.
The US Tactical Combat Casualty Care (TCCC) handbook was created for trained military medics operating in war zones in the 1990s and heavily promotes the use of tourniquets in war, describing their use as “the best method to control life-threatening bleeding”.
Widely adopted by NATO and Western armed forces in the early 2000s, the TCCC standards were quickly integrated into Ukrainian military and civilian medical training following the Russian invasion of Crimea in 2014.
Captain Stevens – though an author of the TCCC – says this was a error.
“If you have a perfect battlefield, then tourniquets work. But if you don’t – if you have a situation like Ukraine today – you can end up with a tragedy. And that’s what the Ukrainians have,” he said.
“There’s now hundreds of thousands of tourniquets that have been distributed to military forces, civilians, fire departments, and police in Ukraine. It’s become a cult, and because it saved lives in Iraq and Afghanistan, people think it’s a good idea,” he added.
While most Western militaries embed specialist medics in every unit, Ukraine’s armed forces – made up largely of conscripts and civilian volunteers – often rely on medics with only a few weeks or even days of training who are often unable to distinguish between injuries that do and don’t require tourniquets.
“The Ukrainian infantry and artillery battalions are undermanned. They can’t replace their medics when they get injured or killed,” Captain Stevens said.
A 2022 study by a Ukrainian military vascular surgeon, Dr Vladyslav Yatsun, found that only 24.6 per cent of war wounded patients arriving at hospital with tourniquets had injuries that justified their use to stop bleeding.
“In all other cases, the use of pressure bandages was more appropriate,” the study said.
They are also often being applied too high on damaged limbs, said Captain Stevens. “They are often taught to place on the tourniquets well above the wounds, and the result is a very high amputation, making it difficult to later fit a prosthesis,” he said.
An updated version of the Ukrainian TCCC disseminated to the armed forces in January 2024 specifically reads: “Place the tourniquet “high and tight” on the wounded extremity.”
NATO has also raised concerns about tourniquets in Ukraine.
Last year, the agency dispatched a team of medical and military experts to investigate what it described as “an unacceptable high complication rate from the use of tourniquets [...] resulting in amputations, renal failure and even death.”
The organisation added: “The current situation with prolonged evacuation times requires a shift in attitude towards tourniquets,” although it has yet to formally publish its recommendations.
Experts stress that tourniquets continue to save many lives and should not be abandoned.
Instead, they say that in places like Ukraine where rapid evacuation is difficult they should only be used in the three circumstances in which they are absolutely necessary.
The first is when a limb has been completely severed. “In that situation, you need a tourniquet, but you need to put it as low down as possible to try and save as much of the limb as you can,” said Captain Stevens.
The second is when the limb is so damaged that it cannot be saved – a decision that requires judgement and medical experience.
The third is when a person has uncontrolled arterial bleeding that cannot be stopped with direct pressure or any other method.
Captain Stevens said tourniquets are often applied by panicked soldiers, who lack the knowledge or confidence to try other methods first.
“When a [Ukrainian] soldier is injured in the field, they’re usually taken care of by other soldiers in a panic,” he said. “They see blood. They put on tourniquets because they have tourniquets. We gave them tourniquets.”
Dr Ostap Zubach, an orthopaedic surgeon who works at a major trauma hospital in L’viv, agrees that while tourniquets can be life-saving, they can also be deadly when used incorrectly.
“As a doctor, I believe that in the right hands, tourniquets are a brilliant thing. But in the wrong hands, they can be very dangerous,” he said.
A particular problem was that many soldiers did not know how to temporarily loosen a tourniquet periodically to extend the time of safe use.
“The strategy of tourniquets [in Ukraine] is just not working, especially when [the soldiers] don’t know how to convert them,” said Dr Zubach. “Many of our soldiers have no experience in the military or medicine.”
Major General Anatoliy Petrovych Kazmirchuk, Commander of the Medical Forces of the Ukrainian Army, introduced tourniquet “conversion” into the basic military training programme last year following reports of excessive amputations and limb loss at the front.
But both Captain Stevens and Dr Zubach are sceptical on what impact the new training is having.
“The problem is that under fire, people are afraid to take the tourniquets down. They’re in a rush to get that patient to a hospital surgeon and don’t stop to convert them,” said Captain Stevens.
A growing group of medics both in and outside of Ukraine are now putting pressure on the ministry of defence to move away from the TCCC handbook and develop their own set of medical guidelines for use in the Ukrainian context, factoring in long evacuation times.
“Guidelines are only guidelines. They require common sense to apply, they require professional judgement. In Ukraine, they don’t have a system for developing guidelines. Often they just take Western, US, British, NATO guidelines, and translate them, word for word into Ukrainian,” said Captain Stevens.
“But there’s a lot of resistance to changing it. The Ukrainians are taking their cue from the Americans, but our protocols were not designed for this situation,” he added.
“If you go back to World War Two and you read what the American theatre surgeons had to say about tourniquets, they said they were dangerous because they were often placed on wounds that did not require them, and then not taken off before it was too late,” he said.
“You didn’t have a rapid evacuation there either. You’re evacuating by land, over bumpy roads, in the middle of the night under fire, just like what the Ukrainians are doing now.”
Both Dr Zubach and Captain Stevens say more emphasis needs to be put on basic casualty care, like cutting off clothes to examine the wound to see the source of bleeding, use of pressure bandages, and alginates – jelly-like dressings that can absorb heavy bleeding and pack into wounds without the long-term risks associated with a tourniquet.
Both agree that tourniquets should be used only as a last resort, when all else has failed. “Soldiers and medics need to understand that when a tourniquet is placed on the Ukrainian battlefield, it usually means an amputated limb,” says Stevens.
The unique circumstances of the Ukraine war are well-positioned to highlight the downsides of TQ use. Namely the minimal training the Ukrainian troops and especially squad medics receive, combined with the inability to rapidly evacuate casualties to a higher level of care due to lack of transportation, lack of air superiority, and constant killer drone presence. These combine to create a perfect storm where TQs are being used when unnecessary, improperly applied, and left on too long.
Now, these issues obviously wouldn't be present in many "normal" non-military scenarios. A wounded LEO or active shooter victim is quite likely to be able to get to a higher level of care in much less than a couple hours. But there's still room for improvement on things like better training on TQ placement and use beyond the common and easy to remember
"Put it high and tight, and use a second one if the first one doesn't full stop the blood flow". Along with an increased emphasis on removing clothing and pocket contents before application, which is often overlooked in many LE/civilian TQ trainings.
But it does present some interesting points about how medical protocols in the US military might also need to be altered while planning for the next peer/near-peer conflict, where we may not have guaranteed medevac all the time. As a result, we might see the TQ start to shift back towards more of a last resort in that context.
And for things like wilderness first aid, or especially those intending to use them for SHTF/prepper purposes, these risks are also much more of a reality.
*It's also worth nothing that the commonly accepted <2 hour window of safety is quite conservative, and not a hard and fast rule. Studies conducted during the GWOT showed that TQs can often be left on for 4-6 hours without further harm. But less time is better, obviously.

Then it isn't a tourniquet problem; it is a logistical problem.
How many of those 75,000 amputees would have died of exsanguination absent application of the tourniquet?

Well, the commonly quoted statistic is that ~50% of military and civilian TQ applications are unnecessary (at least in hindsight).
So probably about half.
But then you also have to factor in the number of those who died because of complications like compartment syndrome or kidney failure from the effects of overuse of TQs, and that meant that some of those who wouldn't have died ended up dying.
But I concur that it's a logistical/training/doctrine issue. And I'm definitely not advocating for
not using TQs.
It's more about highlighting that TQs may not always be a first resort in every situation if it can be managed with something else (or at least converted to something else once in a safer situation if rapid evac isn't going to be possible), and that there's a need for better training in TQ use beyond the quick and easy to remember "High and tight/use as many as needed/go straight to a TQ anytime there's a serious appendage bleed". Which is how TQs are commonly taught in things like basic Stop The Bleed classes and LE training, and seems to have been what's taught to the poorly trained Ukrainian soldiers as well.

I've seen way, way too many TQ applications that were totally unnecessary!
Gunshot to the forearm, calf, outer thigh, bicep, and not a lot of bleeding, yet some dumbass that thinks they are saving lives is slapping on a TQ.
"But that's how we were trained!"
BULLSHIT! No you weren't!
4X4's and some kerlex / gauze, a compression bandage, and about a hundred other things (T-Shirt, towel...) to stop the bleeding until an ambulance gets on scene. Ambulance arrival time for me? less than 10 minutes.

mrvmaxI read something similar earlier this week and I was thinking back to my EMT training in the 90’s. TQ’s were the last resort and were only to be used when nothing else could be done.
I do see quite a few tacticool guys carrying them but I wonder how many have been trained on their use. Had one early 20’s guy say how we needed to have a trauma kit at church in case something happened. I responded, “or we cold call 911 and get the fire department that is 1/8 mile away to respond”. It is staffed 24/7 with fire and medical personnel.
I do have my own trauma bag (with TQ) but that is only carried when I am traveling or out hunting somewhere remote where medical help is not likely.

john1I've used them twice-a suicidal party with down-the-arm slices and a motorcycle accident with amputation.
There was a deputy shot (at my former agency) who was trying to put one on his leg when the SWAT medic got to him and advised he did't need it because there was no major leaking going on. That was a sursprise, as we all thought that a TQ goes on anytime there are holes where there shouldn't be any.

That matches with the training I got in late 80s and early 90s.

Navy was the same way when I was learning to be the "Doc". Tourniquet only if lots of gauze and direct pressure isn't working (and if medevac wasn't on the way). Big T on the forehead. And use belts, rifle slings, socks, boot blousers, etc. first instead of your issued tourniquets; resupply might be iffy for your kit.

Lol. I didn’t even need to read the article to already know that was coming. Bottom line, it’s not the TQ’s fault, now, is it?

jljonesI’m not sure I buy the whole two hour thing.
Years ago, I worked a shooting where the victim took a fairly close range thigh hit that clipped the femoral. Responding officers applied a TQ on scene. It was applied properly but did not fully stop the bleeding. A second TQ was applied directly below it. He was flown from the scene to Vandy. I received photographs of the wound pre-op (about 5 hours later), and our TQ could be seen in the background on the leg. The victim recovered and could walk.
That is a one of but not uncommon for what I’ve seen.
My rule of thumb is “that’s a lot of fucking blood”. When I help my medics teach TCCC, I tell the new guys “if you look down and say to yourself ‘that’s a lot of fucking blood’ you probably need to put a tourniquet on. If not, direct pressure will probably work.”
Well, probably 5 years ago, we taught a class and I said that and everybody giggled. A couple days later, one of my guys responded to an incident where an 18 month old girl was ran over accidentally by a lawn mower. Basically severed the leg above the knee. My guy runs up and you can hear his somewhat panicked voice surveying the horrific scene “Holy fuck that’s a lot of blood”. He took a deep breath and applied a tourniquet. He saved the little girls life. We had a good laugh after the fact about what he blurted out.

ChowserFunny TQ story.
Was on scene and dude was screaming at me to use a tourniquet and I was like what do you want me to do, put it around his neck? I told him to keep applying pressure. I didn't know it was the kid's father. He had three holes in his chest. EMTs arrived shortly thereafter and I went to check on his other kid who had more holes in him.

captain127Right tool right time is the key. A lot of people carry TQ’s and don’t understand this. The VAST majority of extremity GSW’s WON’T need a TQ. Just like quick clot ( we used to call it “magic pixie dust” in the early to mid 2000’s ) it has a place but is not a panacea!
The key here is EDUCATION AND TRAINING
Regarding TQ time I myself working in orthopedic surgery ( controlled environment I know) have seen us put TQ up ( inflating TQ in OR ) and leave it in place for several hours with no I’ll effects. Sure, we try to limit TQ time but it is not always possible.
Direct pressure a good solid dressing and/ or packing the wound is the 90+% solution.

wrightdWhen I was a little kid, I fell on a broken bottle running down the middle of railroad tracks. I was sitting up on my butt on a railroad tie, and the blood was spurting up about a foot or so from my lower leg. A military police officer saw me and scooped me up, and placed clamped his hand on my cut and squeezed it hard, and delivered me to a Navy medical dispensary and a young Lt. doctor placed a blood pressure cuff on my thigh and sewed it up lickity split. Being small I asked him if it was a tourniquet, and I don't remember his answer, but I can tell you that for a very tiny amount of drag on my left lower leg when walking to this day I have no lingering negative effects. If that was a tourniquet per se it was obviously used correctly. That police officer and surgeon saved my life. If he had not seen me passing in his green Navy police truck I would not be here today. I wish I knew who he was, I could have looked him up a long time ago. God bless him, and the Navy surgeon.

armedmdA lot of valid points in the article. Tourniquets can and do save lives when necessary and applied properly. I’d say 30% I see come in from the field aren’t applied properly ie not tight enough. When we get a patient with a tourniquet we assess the ABCs and then release the tourniquet to examine the issue and define our plan for management. Honestly it’s rare that we reapply the tourniquet as the bleeding is stopped. I routinely use a tourniquet for amputations in the OR. Typically the tourniquet is in place for 10-20 minutes depending upon the resident working with me.
The two hour time frame mentioned is extreme. I typically see minimal residual effects if the tourniquet is removed within 4 hours or so. I’ve seen some longer without issues but it’s risky.
