Leaks involving the anesthesia circuit can cause significant complications including hypoxia and hypoventilation. We present a case of a circuit leak caused by damage to the corrugated tubing attributed to improper use of the tube holder. A 58-year-old male was scheduled for resection of a palatal tumor under an intubated general anesthetic. After successful nasotracheal intubation, the anesthesiologist inserted the corrugated tubing of the anesthetic circuit into the tube holder. A leaking sound was heard and a tear in the corrugated tubing was promptly discovered. The corrugated tubing of the anesthetic circuit presumably tore because it was inserted into the groove of the tube holder at an inappropriate angle with excessive force. Anesthesiologists should be aware of potential leaks if the anesthesia circuit is damaged, which may be caused by improper use of tube holders.
麻醉回路泄漏可导致严重并发症，包括缺氧和通气不足。我们报告了一例因波纹管损坏导致的回路泄漏，这归因于管架使用不当。一名 58 岁男性在全身麻醉下接受腭部肿瘤切除术。鼻气管插管成功后，麻醉师将麻醉回路的波纹管插入管架。听到泄漏声后，立即发现波纹管有一处撕裂。麻醉回路的波纹管可能是因为以过大的角度和力插入管架的凹槽而撕裂。如果麻醉回路损坏，麻醉师应注意潜在的泄漏，这可能是由于管架使用不当造成的。
