目的寻找较好的小儿气管异物麻醉的药物。方法３０例气管异物小儿用γ－ＯＨ（ｎ＝２０）及异丙酚（ｎ＝１０）两种麻醉方法。比较麻醉、苏醒时间，麻醉期间循环、呼吸变化，术中及术后并发症或副作用，手术置镜条件及麻醉效果。结果异丙酚组麻醉苏醒时间明显短于γ－ＯＨ组（Ｐ＜０．０５），呼吸抑制较明显，术中ＳｐＯ２下降发生率高，但ＰＯＮＶ发生率低（Ｐ＜０．０５），置镜条件优于γ－ＯＨ组（Ｐ＜０．０５），但两组麻醉效果满意率相似。结论提示应在严密监护下小心使用异丙酚。
Objective To find a better pediatric tracheal anesthesia drug. Methods Thirty children with tracheal foreign bodies were anesthetized with γ-OH (n = 20) and propofol (n = 10). Comparison of anesthesia, recovery time, circulation during anesthesia, respiratory changes, intraoperative and postoperative complications or side effects, surgical placement conditions and anesthesia. Results The anesthesia recovery time in propofol group was significantly shorter than that in γ-OH group (P <0.05), respiratory depression was more obvious, the incidence of SpO2 decreased during operation, but the incidence of PONV was lower (P <0.05) The condition of the microscope was better than that of the γ-OH group (P <0.05), but the satisfaction rates of the two groups were similar. The conclusions suggest that propofol should be carefully administered with close supervision.
