经纤维支气管镜治疗机械通气并发肺部感染的疗效观察

The curative effect of fiberopfic bronchoscope on mechanical ventilation with merger lung infection

目的观察经纤维支气管镜治疗机械通气并发肺部感染的临床效果。方法回顾性分析42例机械通气并发重症肺部感患者的临床资料，均经纤维支气管镜行气道检查、分泌物清除、取痰培养、支气管肺泡灌洗治疗，统计分析治疗前后动脉血气变化情况。结果42例患者共进行了81例次纤维支气管镜检查治疗，治疗后氧分压（PaO：）上升、二氧化碳分压（PaCO：）降低、SaO：升高，与治疗前差异均有统计学意义（t=一188．539、74．481、一9．025，均P〈0．01）；42例痰培养全部呈阳性，阳性率为100％，经过药敏试验进行抗生素调整后，39例患者病情得到改善，有效率92．9％。结论对机械通气并发肺部感染患者经纤维支气管镜灌洗、检查，有利于改善血气，提高治疗效果。

Objective To explore the clinical effect of fiberoptic brenchoseope on mechanical ventilation pa- tients with lung infection. Methods 42 patients with serious lung infection acted mechanical ventilation were carried by fiberoptic bronchscope to check airstract,clear the waset,waste cultivating,and lung washing. Results The waste cultivating was Positive. The conditions of 39 patients were improved effectively. The PaO2 （ t = -188. 539, P 〈 0. 001 ）, PaCO2 （ t = 74. 481, P 〈 0. 001 ）, SaO2 （ t = -9. 025, P 〈 O. 001 ） were statistically different after fiberoptic brenchoscope treatment. Conclusion Fiberoptic bronchoscope could effectively identify the etiology and provide specif- ic antiinflamation treatment;lung washing was beneficial for the airabstract waste extraction to improve the condition which was a relatively safe and effective method.
