Pneumatic tourniquets

ORIGINAL ARTICLES.: PNEUMATIC TOURNIQUETS: WITH ESPECIAL REFERENCE TO THEIR Cushing, Harvey

S urgeons and neurologists alike are familiar with the postoperative palsies of the extremities consequent upon the too energetic and prolonged application of an elastic tourniquet. Out of a considerable number of pressure paralyses, which have come under the writer’s observation during the past two years, eight of them have thus origi­ nated. The greater number of these were of the brachial ty...

Local compression patterns beneath pneumatic tourniquets applied to arms and thighs of human cadavera.

Distributions of tissue fluid pressure were examined beneath a standard pneumatic tourniquet in six upper extremities and six lower extremities of fresh human cadavera, disarticulated at the shoulder and hip, respectively. A standard 8-cm-wide tourniquet cuff was applied at mid-humerus or mid-femur position. Tissue fluid pressures were measured by 100-cm-long slit catheters inserted parallel to...

Measurement of hazardous pressure levels and gradients produced on human limbs by non-pneumatic tourniquets

This paper reports on existing and novel transducers for improved quantitative investigations of the levels of applied pressures and pressure gradients produced on human limbs by non-pneumatic tourniquet straps, and by non-pneumatic elastic bandages and elastic rolls when used as tourniquets, for comparison to benchmark data for pneumatic tourniquet cuffs commonly used in surgery at present.

The effect of pneumatic tourniquets on the ultrastructure of skeletal muscle.

Experiments have been carried out on rhesus monkeys to determine the effect of the application of a pneumatic tourniquet on the ultrastructure of the muscles of the lower limb. Tourniquets were applied for periods lasting between one and five hours. The changes in the muscle lying immediately under the cuff of the tourniquet were more marked than those observed in muscle distal to the cuff. Thr...
