中文摘要：
目的：探讨刷牙冲洗口腔护理法对呼吸机相关性肺炎（VAP）的影响。方法：将100例气管插管机械通气患者随机分为两组实验组与对照组各50例。两组均在机械通气开始24 h内进行口腔护理,2次/d,其中对照组进行常规口腔护理,实验组采用刷牙冲洗法进行口腔护理。比较两组患者口腔护理后细菌培养结果及口臭、口腔溃疡、疱疹、发生率。结果：两组患者口腔护理后细菌培养结果比较差异有统计学意义（P〈0.05）,口臭、口腔溃疡、疱疹、发生率比较差异也有统计学意义（P〈0.01）。结论：采用刷牙冲洗法进行口腔护理能够减少患者口腔定植菌,降低口腔感染发生率,从而达到降低VAP发生率的目的。
英文摘要：
Objective： To investigate the impact of the oral care of brushing the teeth and rinsing the mouth on ventilator-associated pneumonia（VAP）.Methods： 100 patients with mechanical ventilation by tracheal intubation were randomly divided into an experimental group and a control group（50 patients for each group）.In both groups,the oral care was given to the patients 2 times / d within 24 hours since mechanical ventilation had been started.The routine oral care was taken in the control group and the oral care of brushing the teeth and rinsing the mouth was applied in the experimental group.The results of bacterial culture and the incidence of halitosis,mouth ulcers and herpes were compared between the two groups.Results： The difference in the comparison of the results of bacterial culture after oral care was statistically significant between the two groups（P0.05）;there was statistically significant difference in the comparison of the incidence of halitosis,mouth ulcers and herpes between the two groups（P0.01）.Conclusion：The oral care of brushing the teeth and rinsing the mouth can reduce colonized bacteria of the oral cavity and decrease the incidence of oral infections so as to achieve the purpose of reducing the incidence of VAP.
