Tissue Clearance as a Measure of Nutritive Blood Flow and the Effect of Lumbar Sympathetic Block upon Such Measures in Calf Muscle

Abstract

This paper reports the effect of procedures known to alter local blood flow upon the rate of removal of locally injected Na 24 and I 131 . An evaluation of this clearance method as a measure of nutritive blood flow is made. A second purpose is to report the lack of effect upon clearance from calf muscle of lumbar sympathetic block, and to discuss its therapeutic implications.
