A maneuver for improved positioning of a tourniquet in the obese patient.
Proximal positioning of an arterial tourniquet will be greatly facilitated by having an assistant firmly draw the skin and subcutaneous tissue distally prior to positioning the cast padding and tourniquet. This simple maneuver is clearly not part of current practice or training, despite the simplicity and effectiveness. Excessive tourniquet tightening should be avoided prior to fixing the Velcro fasteners, a practice which is commonly employed and is not only ineffective in maintaining proximal tourniquet positioning, but also deleterious in that it creates a "venous tourniquet" effect. Loosening of the restraining adhesive tapes and unnecessary traction of adhesive tape on sensitive skin can be avoided by bringing the extremity to its resting position before fastening the tape proximal to the tourniquet.
