Abstract
Intramuscular pressure detns. by the Kerr-Scott modification of the Henderson technic showed little change in the thigh muscles of the rabbit as a result of nerve stimulation,'' nerve section, arterial and venous occlusion, hemorrhage, spinal cord section and after death. In human muscles, with dense sheaths such as the extensors of the wrist and the knee, voluntary contraction or local venous obstruction increased intramuscular pressure. After spinal anesthesia, no change was found in the intramusc. pressure in human gastrocnemius or biceps. In 14 surgical patients, no correlation between the intramuscular pressure and either the venous pressure or the arterial blood pressure was observed.
