Abstract

An intravascular oxygen tension (PO~2~) sensor (Continucath 1000) was used to assess flap viability in microsurgically revascularized free flaps for 36 hours postoperatively. In vitro, long term stability, linearity, and response time of the PO~2~ sensor proved to be excellent. In 14 patients with sound flaps tissue PO~2~ values were found to be between 15 and 35 mm Hg. In three cases a failing flap needed reexploration. In these cases the PO~2~ sensor was accurate in detecting circulatory failure while in other cases it traced a number of physiological changes. The device holds promise for free flap monitoring but further studies are indicated. © 1993 Wiley‐Liss Inc.
