[摘要] 目的 探讨支气管镜肺泡灌洗治疗小儿重症肺炎的临床效果。方法 方便选择该院儿科于2018年1月—2019年1月收治的小儿重症肺炎100例，采用随机数字表法按1：1分组，分为对照组和观察组，每组50例患儿，对照组给予对症相关的综合治疗;观察组在对照组的基础上加用支气管镜肺泡灌洗方法治疗，观察对比两组患儿在疗效、症状体征改善时间、住院时间指标变化。 结果 两组患儿在住院治疗后，观察组症状体征改善时间比对照组短，差异有统计学意义(P<0.05);观察组住院时间比对照组缩短，差异有统计学意义(t=10.220，P<0.05);观察组的总有效率为96.0%，高于对照组有效率66.0%，差异有统计学意义(χ2=14.620，P<0.05)。结论 小儿重症肺炎用支气管镜肺泡灌洗治疗，可显著提高疗效，改善临床症状体征，同时促进患儿早日康复出院。
