Garrots pneumatiques

Locally, the tourniquet induces tissue lesions resulting from compression, ischemia and reperfusion, and which are associated with postoperative neuromuscular dysfunction. Tourniquets may also generate haemodynamic, respiratory, thermal, neurologic and thrombo-embolic imbalances which are often short-lived but potentially deleterious. During tourniquet compression, some patients develop pain which is not reliably suppressed by anaesthesia, although nociception from the surgical site is abolished. Although surgical tourniquet use is common, its effects must not be underestimated and the decision to employ a tourniquet should take into account not only operative factors but also characteristics specific to each patient.
