目的：探讨支气管肺泡灌洗抢救重症肺炎合并呼吸衰竭的临床价值。方法：将40例重症肺炎并呼吸衰竭患者随机分为灌洗组和对照组，每组20例。对照组采用抗感染、化痰及营养支持治疗等常规治疗手段，灌洗组在常规治疗基础上加支气管肺泡灌洗，观察两组病例的治疗效果。结果：灌洗前PaO2、PaCO2和氧合指数差异均无统计学意义（ P＞0.05），治疗后PaO2、PaCO2明显低于对照组，氧合指数明显高于对照组，差异有统计学意义（P＜0.05）；灌洗组总有效率为100％，显著高于对照组的65.0％，差异有统计学意义（P＜0.05）。结论：支气管肺泡灌洗抢救重症肺炎合并呼吸衰竭，疗效好，可减少使用有创机械通气，有较高的临床价值。%Objective To study the clinical value of the bronchoalveolar lavage in the treatment of severe pneumonia and respiratory fail-ure. Method 40 patients with severe pneumonia and respiratory failure were randomly divided into lavage group and the control group,20 ca-ses in each group,control group adopted anti-infection,eliminating phlegm and nutritional support treatment such as conventional treatments, lavage group on the basis of routine treatment plus bronchoalveolar lavage,the therapeutic effect of two groups of cases was observed. Results The former lavage PaO2,PaCO2 and the oxygenation index were not significant difference(P> 0. 05),PaO2 and PaCO2 were obviously lower than the control group after treatment,oxygenation index was significantly higher than the control group,the difference was statistically signifi-cant( P<0. 05);the total effective rate in lavage group was 100%,which was significantly higher than 65. 0% of control group,the difference was statistically significant( P<0. 05 ). Conclusion Bronchoalveolar lavage rescue severe pneumonia and respiratory failure,good curative effect,can reduce the use of invasive mechanical ventilation,has high clinical value.
