A critical laboratory evaluation of transcutaneous PO2 monitoring and tissue pH monitoring in lower abdominal island flaps based on the superficial inferior epigastric vessels in rabbits revealed that transcutaneous PO2 values correlate poorly with tissue survival under circumstances of decreased arterial inflow. The inability of the transcutaneous PO2 monitor to accurately predict viability of the flaps in this study is attributed to physiologic changes in the microcirculation and not to instrument error. Tissue pH was, in all instances, a reliable index of the perfusion status of the flaps.
一项基于兔腹壁下浅血管的下腹部岛状皮瓣经皮氧分压(PO2)监测和组织pH监测的关键实验室评估显示,在动脉血流减少的情况下,经皮PO2值与组织存活的相关性较差。在本研究中,经皮PO2监测仪无法准确预测皮瓣的存活能力,这归因于微循环的生理变化而非仪器误差。在所有情况下,组织pH都是皮瓣灌注状态的可靠指标。
