Abstract
INTRODUCTION THE PRONOUNCED cutaneous hyperemia upon release of a tourniquet has long been familiar to surgeons. This reaction, which is called reactive hyperemia, has been studied in detail by a number of workers, starting with Lister and including many of the outstanding names in vascular physiology. The period of hyperemia bears a definite relationship to the length of the circulatory arrest. Provided occlusion is not prolonged for more than a few minutes, the duration of the hyperemia is usually one-half to threefourths that of the arrest.1It has been shown that the hyperemia represents the repayment of a blood flow debt which is built up during the period of arrest in the limb distal to the cuff.* The reaction is dependent upon accumulation of local metabolites during the period of arrest and upon the arterial pressure within the limb.4The intense cutaneous hyperemia is the result of dilatationKeywords
