[Percutaneous measurement of oxygen partial pressure as an evaluation method of free flaps]
Abstract:
Transcutaneous, polarographic pO2-measurement can be used to estimate and monitor the circulation in free tissue transfers. Our experience in this field using a modified Clark's electrode is reported by presenting some examples. Its value in intraoperative and postoperative monitoring and for the early diagnosis of a critical reduction of blood flow in free flaps with microvascular anastomoses is assessed in the light of our early experience with this technique.
