危重病肺分泌物不同收集法病原学检测的研究

Mutation of Three Ways of Collecting Pulmonary Secretion in Etiology Detection

目的探讨建立人工气道患者肺分泌物的收集方法。方法分别采用常规法 (A)、1ml注射器法 (B)和无菌玻璃小瓶法 (C)收集肺分泌物 ,对其病原学检测的敏感性、可靠性进行比较。结果B、C两法与A法相比 ,在病原学检出率方面差异有显著意义 (P <0 .0 5 ) ,B、C两法无差异 (P >0 .1) ,但在可操作性方面C法更优于B法。结论无菌玻璃小瓶法是一种简便、快捷。

Objective To study the ways of collecting pulmonary with artifical trachea. Methods Normal way(A)、1ml disinfection syrine way(B)and disinfection small bottle way(C)were used to collect pulmonary secretion,and compared with sensitivity and procedurity in etiology detection. Esults To the rate of bacteria not checkout,B and C were better than A( P <0.05).It was not different between. Band C ( P >0.1),But C was more simply than B.Conclusion:C was simplicity、rapidity was of collecting pulmonary.
