2例全麻诱导下气管插管致气管内肿物出血的处理

Treatment of intratracheal tumor hemorrhage caused by endotracheal intubation under induction of general anesthesia in 2 patients

报道2例术前无呼吸道梗阻症状的患者，行全麻气管插管引起气管内肿物出血的抢救。纤维支气管镜检是诊断气管内肿物的金标准。导管套囊封堵气管下段，头低位及时吸引气管内出血可有效减少两肺血液灌注，改善患者氧供和通气状况。

This report described the emergency treatment process of intratraeheal tumor hemorrhage caused by endotracheal intubation under induction of general anesthesia in 2 patients without preoperative airway obstruction. Fibreoptic bronchoscopy is the best choice for diagnosis of intratracheal tumor. Blocking the lower trachea off by inflating the cuff of endotracheal tube and sucking out the trachea hemorrhage timely with trendelenburg position can reduce aspirated blood effectively and improve oxygen supply and ventilation.
