气管切开是保持呼吸道通畅的重要措施，几年来在临床上遇到的重伤员在救治中早期行气管切开术获得较好效果，现就临床意义简要评述。气管插管在呼吸骤停及现场抢救中有特殊的优越性，便于快速人工控制呼吸。但有明显局限性：在严重创伤休克病员气管插管可诱发呼吸心跳骤停，使 Tracheotomy is an important measure to maintain airway patency. In recent years, critically ill patients encountered in clinical practice in early treatment of tracheotomy get better results, the clinical significance of a brief review. Endotracheal intubation in the respiratory arrest and on-site rescue have special advantages, to facilitate rapid manual control of breathing. But there are obvious limitations: tracheal intubation in patients with severe traumatic shock can induce respiratory arrest, so that
