Tourniquets were used successfully on thousands of U.S. casualties in Iraq and Afghanistan, saving a great many lives without causing significant complications.
However, not every extremity wound requires a tourniquet for bleeding control.
The conflict in Ukraine has demonstrated what can happen when evacuations to surgical care are delayed and tourniquets are left in place for many hours. Complications, including limb amputation, acidosis, hyperkalemia, kidney failure and death have been noted.
These complications are especially tragic when tourniquets are applied for bleeding that is minor and is not life-threatening. Multiple studies have shown that up to 75% of prehospital tourniquets applied in Ukraine were not actually needed.
In this new TCCC Quick-Look presentation, Dr. Frank Butler, Dr. John Holcomb, and Dr. Warren Dorlac address this issue. They provide a description and a series of photos and illustrations to show what kind of bleeding is truly life-threatening and requires a tourniquet for initial control of the hemorrhage.
Understanding the difference matters. Limbs should not be lost to tourniquets applied for minor bleeding.
This presentaion will be followed by a second TCCC Quick-Look presentation on Tourniquet Reassessment.
