INTRODUCTION

The efficacy and safety of the tourniquet are discussed, in particular with regard to the blood saving and tissue damage induced by ischemia. The quality of exsanguination and tissue necrosis in the compression zone are significant prognostic factors. The objective of this study was to evaluate the efficacy and safety of a new tourniquet system combining efficient and controlled exsanguination (figure 1) and ischemia maintained by pressure on a minimal surface (figure 2). The hypothesis tested was that the new system allowed tourniquet to reduce blood loss compared to conventional withers without increasing the risk of complications.
