Endotracheal tube block due to various mechanical causes such as mucous, blood clot, denture, and ampoules have been reported. A patient of achalasia cardia with chronic passive aspiration pneumonitis developed mucoid mass in the respiratory passage which dislodged during the surgical procedure. The episode occurred almost an hour after induction of anesthesia and the dislodged mucoid mass blocked the lumen of endotracheal tube, leading to hypoxia and impending cardiac arrest. However, the patient was salvaged by replacing the tube.
已报道过由于各种机械原因导致的气管内导管阻塞，如黏液、血凝块、假牙和安瓿等。一名患有贲门失弛缓症并伴有慢性被动性吸入性肺炎的患者，其呼吸道出现了黏液样肿物，该肿物在手术过程中脱落。该事件发生在麻醉诱导后近一小时，脱落的黏液样肿物阻塞了气管内导管的管腔，导致缺氧和即将发生的心脏骤停。然而，通过更换导管，患者得以挽救。
