An improvise tourniquet properly applied high and tight on a thigh

Critics of improvised tourniquets say they are ineffective. Some claim, “if you’re planning to improvise, you’re planning to fail.”We disagree with this statement. Proper planning includes having a primary plan, in this instance a commercially available tourniquet, and an alternate plan:

What happens when you run out of tourniquets in your mass casualty event? You improvise.

The literature most quoted in opposition to improvised tourniquets is Colonel John Kragh’s article: Practical use of emergency tourniquets to stop bleeding in major limb trauma.1 That article noted a 25% success rate of hemorrhage control with the application of improvised tourniquets placed on casualties treated at a combat support hospital in Iraq in 2006.

However, when looking at the medical literature, one has to read deeper in a study than just the abstract to evaluate the application of this data.

The study evaluated a grand total of 16 improvised tourniquets which were placed on 15 injured limbs involving 15 casualties. Of the 16 improvised tourniquets placed, four were felt to be effective. This obviously is not a glowing endorsement for improvised technique. However, the 16 improvised tourniquets consisted of “cravats, dressings, a string, a belt, a cord, a band, and intravenous tubing.” These are not properly improvised tournqiuets.

The study noted that the wider improvised tourniquets, made from cravats, particularly when two were applied side by side were more effective, specifically 42% (3 of 7) of limbs.1

At the conclusion of the article, the authors make several recommendations, among them: “Use scientifically designed, laboratory tested, and clinically validated tourniquets. Use improvised windlass tourniquets when scientifically designed tourniquets are unavailable.”1 We wholeheartedly agree.

Second, an IDF study published in 2003 found that “the improvised Russian tourniquets (defined as improvised at the scene using a nonelastic strap wrapped around the injured limb and tightened with a wooden stick) applied to thigh wounds succeeded at stemming active bleeding in 72% of cases.”2

Lastly, in an article by Swan, ten improvised tourniquets were made from “discarded” cloth. The cloth was sized to 48 x 12 inches, folded to three inches wide, and utilized a 12-inch stick “from a woodpile.” The improvised tourniquets were placed on volunteer thighs and tightened until intolerable pain or cessation of posterior tibial artery pulse, measured by Doppler ultrasound. They were effective in 9 out of 10 volunteers. One volunteer could not tolerate the discomfort before complete occlusion.3

Improvised tourniquet supplies should include a wide piece of fabric, a military cravat is an excellent choice, and a sturdy windlassHow to make a proper improvised tourniquet?

A properly improvised tourniquet uses a strip of fabric. It should be 2-4” wide and long enough to wrap several times tightly around the casualty’s limb. We like military cravats, as a good, multi-purpose piece of kit.

  • After tying a square knot, a windlass must be used to adequately tighten the improvised tourniquet. 
  • Next, lifting up slightly while twisting can often avoid pinching the casualty and decrease discomfort. 
  • Lastly, the windlass must then be secured, preferably with another triangular bandage or cravat. 

For a contingency plan, a satisfactory improvised tourniquet can be made using the casualty’s own clothing by cutting their pant leg or shirt sleeve, while the casualty is still wearing it. A windlass must be used to tighten the fabric/tourniquet.

Finally, remember the windlass will then be “lost” to further use. For this reason, flashlights, magazines, and shears are not our favorite windlasses because those items probably need to be used for other jobs. Almost any narrow, rigid item could work and Col. Kragh also found chopsticks are adequate.4 A metal pen is a good choice as well. You simply need something stout enough, and long enough to allow you to twist it, not break under strain, and be able to secure it in place.

Given a choice, a clinically proven tourniquet is our first option. If given no options, we train to effectively stop massive hemorrhage using what is on hand.
