We experienced a case of burn produced by the pulse oximeter probe at the finger of a patient. Patient was a 75-year old man scheduled to transurethral prostatectomy. The pulse oximeter probe made by Physio-Control Co. was attached at his finger and was connected to a pulse oximeter manufactured by Ohmeda Co. Soon after the start of Spo2 measurement the anesthetist became aware of abnormal heating of the probe and removed it immediately. But unfortunately a small thermal injury was formed at patient's finger. Abnormally excessive current went through the detector diode and heated the finger probe. Attention to correct connection between the pulse oximeter probe and the finger is necessary before use.
我们遇到了一例患者手指被脉搏血氧饱和度仪探头烫伤的病例。患者是一名75岁男性，计划进行经尿道前列腺切除术。由Physio-Control公司生产的脉搏血氧饱和度仪探头附着在他的手指上，并连接到Ohmeda公司生产的脉搏血氧饱和度仪上。在开始测量血氧饱和度（Spo2）后不久，麻醉师就察觉到探头异常发热，立即将其取下。但不幸的是，患者手指上形成了轻微的热损伤。异常过大的电流通过检测二极管，导致手指探头发热。使用前必须注意脉搏血氧饱和度仪探头与手指之间是否正确连接。
