Transcutaneous oxygen tension monitoring during vascular reconstruction.
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.
