Transcutaneous Po2 Measurement in the Detection of Amputation Level - Preliminary Report -

截肢後的復健常取決於手術後斷肢的長短，截肢位置的決定，受很多因素的影響。許 多有關表皮含氧量測定的研究報告，認為截肢位置若表皮含氧量25至40毫米汞柱以上 時，則傷口的癒合良好，在我們的實驗裡，初步的結果顯示，只要表皮含氧量高於16 毫米汞柱處作膝下截肢手術，其傷口的癒合能順利進行。 The success of rehabilitation following amputation is directly related to the level of limb loss. Factors determining the ideal level for amputation in a patient with gangrenous foot are many and complicate. In the past years many investigators have been exploring the use of transcutaneous oxygen tension ( TcPO2) measurement as a non-invasive means in the determination of amputation level. They found that if TCPO2 at the amputation level higher than 25-40 mmHg, there was no problem in the healing of the wound in the stump. In this report we preliminarily show our experience in this aspect that there was no delayed wound healing in the below-knee (B -K) amputation if the TcPO2 at the amputation level is higher than 16 mmHg.
