对下呼吸道感染三种不同取痰培养方法的对比研究

目的探讨用三种不同方法取痰培养对明确下呼吸道感染病原菌的价值.方法对58例下呼吸道感染的患者进行了三种不同方法取样培养.结果普通自然咳痰培养(下文简称PZK)标本合格54例,占93.1%;培养阳性16例,占29.63%;用复方洗必泰含漱液漱口后取样(下文简称FXHY)标本合格56例,占96.55%;培养阳性28例,占50%;用经纤支镜防污染毛刷取样(下文简称FBPSB)标本合格58例,占100%;培养阳性32例占55.2%,FXHY与PZK比较P＜0.05有差异,FXHY与FBPSB比较P＞0.05无差异,且FXHY与FBPSB阳性符合率为81.3%.结果FXHY取痰法是一种简便易行,且阳性较高的一种方法.

Comparative research of three ways for taking phlegm specimen and its culture in lower respiratory tract in fection

Objective: To investigate the value of identifying the pathogenic bacteria from the lower respiratory tract infection by three different ways of taking phlegm and culture of it. Methods: 58 patients with lower respiratory tract infection were enrolled in this study. Phlegm specimens were taken by the three different ways and cultured. Results:By PZK, qualified specimens were got from 54 cases, (amounting to 93.1%), with 16 positive cases which accounting to 29.63% .By FXHY , there were 56 qualified cases(to 96.55% ), with 28 positive cases(50% ).By FBPSB, all cases are up to the standard, with 32 positive cases, for 55.2%. The positive rates of culture was significantly increased by FXHY(P<0.05) than PZK. But the rates was no different from FXHY group and FBPSB group(P<0.05). Conclusion: It suggests that FXHY method is an easy and convenient one and higher positive rate could be echieved.
