目的：探讨吸入麻醉诱导下大鼠气管插管的方法。方法：100只SD大鼠,吸入麻醉箱诱导后,将大鼠固定于拱形气管插管台上,采用能穿透颈部组织的冷光源照射定位后,经钢丝引导采用14G留置针经口气管插管。结果：气管插管成功率为93%,麻醉后无死亡,麻醉1周后解剖10只大鼠,未发现有咽喉部疤痕和狭窄。结论：吸入麻醉诱导下经口明视气管插管方法为一种有效的,成功率较高的大鼠气管插管方法。

Objective：To explore the method of endotracheal intubation in adult rats after induction by inhalation anesthesia.Methods：The animal,anesthetized with isoflurane,was fixed to a arched platform in a dorsal position by means of a ribbon hooked around the upper incisors,wire guide 14-gauge intravenous catheter served as an endotracheal tube.Results：The success rate of orotracheal intubation was 93%,No rat died after anesthesia,and the postmortem examination and measurements in the upper airway confirmed that the endotracheal tube was properly sited and also demonstrated the precise size of the device that should be used.Conclusion：The method of endotracheal intubation after induction by inhalation anesthesia is an effective and simple technique and deserves applying.
