摘要
目的探讨气管切开术后患者呼吸道感染与环境因素的相关性。方法 60例外科行手术治疗的患者,随机分为研究组(气管切开术后患者)和对照组(未进行气管切开术危重患者)各30例,观察两组患者术后第1、3、7天痰液p H值改变前后周围的物品、空气、咽部分泌物、护理人员手部带菌情况,对两组患者呼吸道感染发生率、口咽部细菌定植种类及改变情况、病原微生物的发生与分类情况进行观察和比较。结果对照组术后第1、3、7天呼吸道感染的发生率分别为3.3%、26.7%、36.7%,研究组分别为13.3%、40.0%、60.0%,两组相比,差异具有统计学意义(P<0.05);空气中含有一定数量的铜绿假单胞菌、金黄色葡萄球菌、肺炎克雷伯菌、阴沟杆菌、粘质沙雷菌、中间葡萄球菌,而研究组下呼吸道分泌物中主要菌群检出率均明显高于对照组,差异具有统计学意义(P<0.05)。结论气管切开术后患者呼吸道感染与环境因素密切相关,应引起重视。
Objective To investigate correlation between patients＇ respiratory tract infection after tracheotomy and environmental factor. Methods A total of 60 patients undergoing surgical operation were randomly divided into research group（patients after tracheotomy） and control group（critical patients without tracheotomy）, with 30 cases in each group. Observation and comparison were made on germ-carrying status of materials, air, pharyngeal secretion and nursing staff before and after p H changes, incidence of respiratory tract infection, type and change of pharyngeal bacterial colonization, occurrence and type of pathogenic microorganism in 1, 3, 7 d after operation of the two groups. Results The control group had incidence of respiratory tract infection in 1, 3, 7 d after operation as 3.3%, 26.7%, and 36.7%, and the research group had that as 13.3%, 40.0% and 60.0%. Their difference had statistical significance（P〈0.05）. There were pseudomonas aeruginosa, staphylococcus aureus, klebsiella pneumonia, enterobacter cloacae, serratia marcescens, and staphylococcus intermedius in the air. The research group had much higher detection rate of main flora in lower respiration secretion than the control group, and their difference had statistical significance（P〈0.05）. Conclusion There is a close correlation between patients＇ respiratory tract infection after tracheotomy and environmental factor, and that is worth attention.
