title: Transcutaneous oxygen tension monitoring during vascular reconstruction.
abstract: Transcutaneous oxygen tension (TsPO2) was measured in the foot and chest of 39 patients with severe peripheral vascular disease and the Regional Perfusion Index (RPI) calculated (RPI = Foot TcPO2 divided by Chest TcPO2). TcPO2 was equivalent to RPI as a measure of ischaemia and furthermore RPI did not alter significantly when re-assessed under anaesthesia. Successful vascular reconstruction brought about an ontable rise in RPI which rose further but not significantly post-operatively. Continuous monitoring of RPI allowed intra-operative identification of 20 of 22 successful reconstructions and there were no false positive results.
