摘要
目的探讨经纤支镜获取无污染痰标本对下呼吸道感染的病原学诊断的价值。方法 225例下呼吸道感染患者随机分为纤支镜取痰组和常规取痰组,将获取的痰标本进行细菌培养并对培养结果进行分析。结果经纤支镜获取痰标本培养阳性率65.7%,常规获取痰标本痰培养阳性率62.5%,两组阳性率比较无统计学差异,P>0.05。结论经纤支镜获取痰标本与常规痰培养阳性率比较无差异,常规痰培养仍不失为下呼吸道感染病原学检测的首选方法。
Objective To ascertain the value of clinical etiology diagnosatients of lower respiratory tract.Methods 225 cases were divided randomly into postbronchoscopy group and control group.The result of sputum culture of the two groups were compared.Results No significant difference in positive sputum culture was found between the postbronchoscopy group（65.7%） and the control group（62.5%）,P0.05.Conclusion There was no significant difference in the sputum culture rate between two groups.Conventional sputum culture is still practical method for the diagnosis of clinical etiology of lower respiratory tract.
