机械通气患者肠内营养同时行胃肠减压对呼吸机相关性肺炎的影响

摘要

目的 探讨机械通气患者肠内营养同时行间断胃肠减压对呼吸机相关性肺炎(VAP)的影响.方法 将80例机械通气患者按入住时间的单双日分组,双日为观察组,经鼻胃管肠内营养同时行间断胃肠减压;单日为对照组,经鼻胃管肠内营养未行胃肠减压.观察两组呛咳、呕吐、X线胸片改变和痰培养结果,比较两组患者VAP的发生率.结果 观察组VAP发生率为40.0％,对照组VAP发生率为82.5％,两组比较差异有统计学意义(P＜0.01).结论 经鼻胃管肠内营养同时行间断胃肠减压可明显降低机械通气患者VAP的发生率.%Objective To investigate the influence of enteral nutrition with intermittent gastrointestinal decompression on the incidence of ventilator associate pneumonia(VAP) in patients with mechanical ventilation. Methods Eighty patients with mechanical ventilation were divided into two groups. The patients in the experimental group received enteral nutrition and intermittent gastrointestinal decompression,while the patients in the control group receiving enteral nutrition without gastrointestinal decompression. The incidence of irritating cough,vomiting,imaging change and bacterial culture of sputum in the two groups were observed. The incidence of VAP was compared between the two groups. Results The rate of VAP in the experimental group (40 percent) was significantly lower than that of the control group(82.5 percent,P<0.01). Conclusion Enteral nutrition with intermittent gastrointestinal decompression can obviously reduce the rate of VAP in patients with mechanical ventilation.
