Mitigating Damage to Injured Limbs After Tourniquet Application
When faced with a traumatic injury, tourniquets can control bleeding and save lives. But because they restrict blood flow to tissues, with prolonged use, these life-saving pieces of equipment can also cause damage to limbs or life-threatening ischemic complications. To solve for this, Giorgio Giatsidis, MD, PhD, is developing a device that uses controlled, localized cooling to minimize the ischemic damage in injured limbs to which a tourniquet is applied. The goal is to apply the device to injured limbs immediately after application of a tourniquet, and then remove the device at the same time as the tourniquet, when blood flow to the limb is restored. A tool like this, utilized in civilian and military trauma settings, would reduce the amount of limb damage, amputations, and systemic injuries that can follow tourniquet application.
