The Value of the Photoplethysmograph in Monitoring Skin Closure in Microsurgery

Abstract

Excessive tension during skin closure may impair flow in a free tissue transfer. Objective methods to observe skin perfusion have been developed. One of these, photoplethysmography, is commonly used for postoperative observation of flow in free flaps. This article demonstrates that valuable information can be obtained with photoplethysmography during wound closure also.
