Tourniquet being applied to an arm on a training dummy A combat tourniquet commonly used by combat medics (military environment) and EMS (civilian environment).. A tourniquet is a device that is used to apply pressure to a limb or extremity in order to create ischemia or stopping the flow of blood.
Esmarch bandage (also known as Esmarch's bandage for surgical haemostasis or Esmarch's tourniquet) in its modern form is a narrow (5 to 10 cm (2.0 to 3.9 in) wide) soft rubber bandage that is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet. The limb is often elevated as the elastic ...
At the beginning of the surgery a tourniquet will be applied to the limb. A tourniquet compresses and controls local arterial and venous circulation for about two hours. The constriction band must be dissected very carefully to avoid damaging the underlying neurovasculature. When the constriction band is excised, there will be a direct closure.
The success rate for tourniquets applied to upper limbs was 94% while the success rate for tourniquets applied to lower limbs was 71%. [39] The difference between the success rates can be attributed to the tourniquets themselves, as in another study, tourniquets applied on healthy volunteers resulted in a much lower success rate for lower limbs ...
The oldest known surgical amputation was carried out in Borneo about 31,000 years ago. [10] The operation involved the removal of the distal third of the left lower leg. The person survived the operation and lived for another 6 to 9 years. This is the only known surgical amputation carried out before the Neolithic Revolution and its farming ...

Correct use of tourniquet devices has been shown to save lives under austere conditions with comparatively low risk of injury. In field trials, prompt application of emergency tourniquets before the patient goes into shock are associated with higher survival rates than any other scenario where tourniquets were used later or not at all.

Another method of achieving constriction of the supplying artery is a tourniquet - a band tied tightly around a limb to restrict blood flow. Tourniquets are routinely used to bring veins to the surface for cannulation, though their use in emergency medicine is more limited. Many armies carry a tourniquet as part of their personal first aid kit.
