两种卧位对机械通气患者呼吸机相关性肺炎的影响

目的探讨两种卧位对机械通气患者呼吸机相关肺炎（ventilator associated pneumonia,VAP）的影响。方法按患者住院号或就诊卡号单双数将行机械通气〈48h的177例患者分为实验组88例和对照组89例。遵医嘱对两组患者进行治疗并采取相同的护理措施,同时实验组患者采取30～45°半卧位,对照组患者采取≥15°但〈30°的半卧位。比较两组VAP发生率及其死亡率和住院时间。结果实验组VIP发生率较对照组低,住院时间较对照组短,两组比较,差异具有统计学意义（均P〈0.05）;两组VAP患者死亡率比较,差异无统计学意义（P〉0.05）。结论机械通气患者采用床头抬高30～45°的半卧位可以降低VAP的发生,缩短住院时间。

Effects of two decumbent positions on ventilator-associated pneumonia

Objective To study the effects of two decumbent positions on ventilator-associated pneumonia（VAP）.Methods 177 patients undergoing mechanical ventilation for less than 48 hours were divided into observational group（n = 88） and control group（n = 89） based on their odd or even registration numbers.The patients at the observation group took the semi-decumbent position at an angle of 30° ～ 45°,while those in the control did at an angle of 15°～30°.The two groups were compared in view of VAP incidence,mortality and hospitalization duration.Results The VAP incidence in the observation group was significantly lower than that of the control group（P 0.05） and the hospitalization duration significantly shorter than that of the control group（P 0.05）,but the difference in the mortality rate between the group was insignificant（P 0.05）.Conclusion The semi-decumbent position at the angle of 30°～45° may be effective in lowering the VAP incidence and shorten the hospitalization duration.
