We experienced the leak of anesthetic gases inside the anesthesia machine in spite of performing the leak test before its use. After induction of anesthesia, a laryngeal mask airway was inserted and the patient was ventilated manually. At the beginning we could not find any signs of machine troubles. High airway pressure occurred immediately after switching to the mechanical ventilation. Because we could not detect the details of the machine trouble, tidal volume was set lower and the surgery was continued. After surgery, we found a crack in a fresh gas circuit valve. We have to check the anesthesia machine regularly and know its duration of use.
尽管在使用前进行了漏气测试，但我们仍经历了麻醉机内部麻醉气体泄漏的情况。麻醉诱导后，插入喉罩气道并对患者进行手动通气。一开始我们没有发现任何机器故障的迹象。切换到机械通气后立即出现了高气道压力。由于我们无法检测到机器故障的细节，因此将潮气量设置得较低并继续进行手术。手术后，我们发现新鲜气体回路阀有一条裂缝。我们必须定期检查麻醉机并了解其使用时长。
