目的探讨远端导管方法与普通方法支气管肺泡灌洗对肺部感染细菌培养阳性率的影响。方法将呼吸病区60例肺部感染患者随机分为实验组和对照组,各30例。实验组和对照组分别行远端导管方法和普通方法支气管肺泡灌洗。将两组灌洗液送普通细菌培养,统计对比培养阳性率。结果实验组培养阳性率显著高于对照组,差异具有统计学意义(P<0.01)。结论远端导管方法支气管肺泡灌洗较普通方法支气管肺泡灌洗对肺部感染细菌培养更有价值。
Objective To investigate the effect of distal catheterization and common method of bronchoalveolar lavage on the positive rate of bacterial infection in lung infection. Methods Sixty patients with lung infection in respiratory area were randomly divided into experimental group and control group, with 30 cases in each group. The experimental group and the control group were treated with distal catheter and bronchial alveolar lavage respectively. The two groups of lavages were sent to ordinary bacterial culture, statistical contrast positive rate of culture. Results The positive rate of the experimental group was significantly higher than that of the control group, the difference was statistically significant (P <0.01). Conclusion The distal catheterization of bronchoalveolar lavage is more valuable than bacterial bronchoalveolar lavage for bacterial infection of lung infection.
