改良式口腔护理方法对经口气管插管患者口腔护理的效果研究

目的寻找普遍适用于经口气管插管患者的口腔护理方法，预防或减少感染的发生。方法将60例经口气管插管患者随机分为试验组30例和对照组30例，试验组采用改良式口腔护理方法，使用Oral-B牙刷、口镜、吸唾管、棉棒进行口腔护理；对照组采用传统的口腔护理方法。观察两组患者口腔护理后牙菌斑、口腔细菌株数有无差异。结果两组患者口腔护理后牙菌斑指数、口咽菌减少和转阴株数比较差异均有统计学意义（P〈0．05）。结论改良式口腔护理方法能有效去除牙菌斑，减少细菌数量，预防感染的发生。

Study on effect of modified oral nursing method for patient with oral endotracheal tube

Objective To find a effective and generally applicable oral-nursing method to prevent microorganism infection for patient with oral endotracheal tube. Methods 60 patients with oral endotracheal tube were randomly divided into two groups . Intervention group (n=30) was performed with the modified oral care method :Oral-B toothbrush instead of cotton balls, mouth mirror instead of a tongue depressor , aspirator tube instead of suction tube and swab instead of washing method . Control group (n = 30) was performed with traditional oral care. The dental plaque clearance and the number of oral bacteria and bacteria in sputum were analyzed in the two groups. Results The number of dental plaque and the number of oral bacteria after oralnursing in intervention group were significantly lower than those in control group with traditional oral care (P＜0. 05, P ＜ 0. 05) . Conclusions Modified oral care method is effective in removing the dental plaque, reducing the number of bacteria and preventing infection.
