Pulse oximetry for vascular monitoring in upper extremity replantation surgery.
Pulse oximetry as a postoperative monitor for replanted or revascularized digits was evaluated experimentally and clinically. The accuracy of detection of vascular occlusion was 100%, and arterial and venous occlusion could be differentiated by changes in pulse inflow and oxygen saturation. Digits demonstrating O2 saturations above 95% remained viable, those below 85% were associated with venous occlusions, and those with no saturation represented arterial occlusions. This method is simple, noninvasive, continuous, and accurate, and it reliably assesses revascularized digits and replanted parts.
