改良口腔护理方法预防呼吸机相关性肺炎的效果观察

The effect observation of improved dental nursing in prevention of ventilator-associated pneumonia

目的:观察改良口腔护理方法在预防呼吸机相关性肺炎(VAP)中的效果。方法:将72例经口气管插管机械通气患者随机分为两组,常规组(n=36)采用传统口腔护理方法,改良组(n=36)采用改良口腔护理方法。观察和比较两组患者口腔霉菌、口腔溃疡、VAP发生率及平均机械通气时间、平均住ICU时间。结果:与常规组比较,改良组患者口腔霉菌、口腔溃疡、VAP发生率、平均通气时间及平均住ICU时间均明显降低或缩短(P<0.05)。结论:改良口腔护理方法能克服常规口腔护理方法的不足,达到彻底清洁口腔、有效预防VAP发生的作用。

Objective：To observe the effect of improved oral care in prevention of ventilator - associated pneumonia （VAP）. Methods ：72 cases of orotracheal intubation in mechanically ventilated patients were randomly divided into two groups, the conventional group （n = 36） was used the traditional oral care,and the improvement group （ n = 36） was used the improved oral nursing. The incidence of oral fungal, oral ulcers, VAP, the average duration of mechanical ven- tilation and the average ICU stay time in two groups were observed and compared. Results ： Compared with the conventional group, the incidence of oral fun- gal, oral ulcers, the VAP, the average mechanical ventilation time and the average duration of ICU stay in the improvement group were significantly reduced or shortened （ P 〈 0.05）. Conclusion ：The lack of the conventional oral care methods can be overcome by improved dental nursing methods. It can clean the mouth thoroughly ,and prevent the occurrence of VAP effective.
