This study validates a simple clinical method used to determine optimum time for flap transference. Temperature was used as an indirect measurement to determine blood flow. By means of a needle thermocouple, temperature differences in a variety of flaps were measured. Differences between the base and most distal portion from the blood supply were recorded. The method was first developed on the dog and then applied to patients. It was found that temperature differences of 2.5 degrees C or less insured flap success. Greater temperature differences increased the chance of necrosis.
本研究验证了一种用于确定皮瓣转移最佳时间的简单临床方法。温度被用作测定血流的间接指标。通过针型热电偶测量了多种皮瓣的温度差异。记录了皮瓣基部与血供最远端之间的温度差异。该方法首先在狗身上开展，然后应用于患者。结果发现，温度差异在2.5摄氏度及以下可确保皮瓣转移成功。温度差异越大，坏死的几率越高。
