可冲洗气管导管预防呼吸机相关肺炎的临床观察

Clinical observation of preventive effect of endotracheal tube on ventilator-associated pneumonia

目的:观察可冲洗气管导管在预防呼吸机相关性肺炎中的价值。方法:将经鼻气管插管行机械通气的患者随机分成观察组和对照组,观察组使用可冲洗式气管导管,对照组使用普通气管导管,分别记录两组呼吸机相关性肺炎发生情况。结果:观察组呼吸机相关性肺炎发生率为21.6%,发生时间13±4天,对照组发生率为48.7%,发生时间6±3天,存在着显著性差异。结论:正确使用可冲洗气管导管,可减少呼吸机相关性肺炎的发生。

Objective： To observe the prevention effect of endotracheal tube on ventilator-associated pneumonia （VAP）. Methods： Patients undergoing mechnical ventilation were divided into observational group and control group. The observational group treated with en- dotracheal tubes, and the control group common tubes, then the occurrence of VAP was recorded in each group. Results： The incidence rate of VAP was 21.6% in observational group, and the average time length was 13 ± 4 days, while the rate in control group was 48.7%, and time length was 6 ± 3days. There were statistically significant difference between the two groups. Conclusion： Proper use of endotracheal tube can reduce the occurrence of VAP.
