口腔颌面部位于呼吸道上端,因外伤及术后组织移位,舌后坠、组织水肿、分泌物阻塞气管插管全麻后喉头水肿等,造成呼吸道梗阻,如不紧急抢救,因缺氧,二氧化碳积蓄,将很快导致心跳停止.患者将因全身缺氧而死亡。我们从1977年至1987年3月,曾遇到5例。现结合临床资料将体会教训报告如下。 Oral and maxillofacial region is located in the upper respiratory tract, due to trauma and postoperative tissue displacement, tongue fall, tissue edema, secretions obstruction tracheal intubation general anesthesia laryngeal edema, resulting in airway obstruction, if not emergency rescue due to hypoxia, Carbon dioxide savings, which will soon lead to a cessation of heartbeat, will result in death from systemic hypoxia. From 1977 to March 1987, we encountered 5 cases. Now combined with clinical information will experience lessons learned as follows.
