目的：总结用机械通气救治急性呼吸窘迫综合征的经验。方法：５０例患者在确保气道通畅的同时，适时给予机械通气：伤后２４ ｈ内通气３８例，２—３ ｄ后机械通气 １０例，５ ｄ后通气２例，通气天数为 ５—７ ｄ。结果：４２例痊愈，８例死亡。死亡原因为多脏器功能衰竭。结论：创伤性急性呼吸窘迫征一旦发生，应在严密监测情况下及早给予呼吸机辅助通气。 Objective: To summarize the experience of using mechanical ventilation in the treatment of acute respiratory distress syndrome. Methods: Fifty patients were given mechanical ventilation timely while ensuring airway patency: 38 cases were ventilated within 24 hours after injury, 10 cases were ventilated after 2-3 days, 2 cases were ventilated after 5 days, and the days of ventilation were 5-7 d. Results: 42 cases recovered and 8 died. The cause of death was multiple organ failure. CONCLUSIONS: In the event of a traumatic acute respiratory distress syndrome, ventilator-assisted ventilation should be given as early as possible with close monitoring.
