目的 观察使用纤维支气管镜支气管肺泡灌洗治疗重症肺部感染的临床疗效。方法 选取2010年2月-2015年10月收治 经纤维支气管镜肺泡灌洗治疗的重症肺部感染患者30例作为观察组，另选取同期未经纤支镜治疗的该病患者30例作 为对照组，对比两组临床疗效。结果 观察组治疗显效率及总有效率高于对照组，且临床症状消失时间、机械通气 时间及住院时间均明显短于对照组，P＜0.05，差异有统计学意义。结论 使用纤支镜对重症肺部感染患者进行支气 管肺泡灌洗治疗，能够有效提高临床疗效，改善临床症状，且能有效缩短治疗时间，具有良好的临床应用效果及价 值。

Objective To investigate clinical observation of bronchoalveolar lavage by fiberoptic bronchoscopy in severe lung infection. Methods 30 patients with severe pulmonary infection form Feb. 2010 to Oct. 2015 treated by fiberoptic bronchoscopy lavage were selected as the observation group, while 30 patients without bronchoscopic treatment were selected as controls group for clinical efficacy comparison. Results The treatment efficiency and total efficiency of observation group was higher, and the clinical symptoms disappeared time, mechanical ventilation time and hospital stay were shorter than the control group with statistically significant (P<0.05). Conclusion By use of bronchoalveolar lavage bronchoscopy for patients with severe pulmonary infection can improve the clinical efficacy, the clinical symptoms and shorten the treatment time effectively, which has a good clinical effect and value.
