摘　　要：目的 研究密闭式吸痰管合理的更换时间.方法 选择建立人工气道接受机械通气且均使用密闭式吸痰管吸痰的患者147例,按抽签法随机分为3组,第1组54例,每24小时更换1次吸痰管；第2组52例,每72小时更换1次吸痰管；第3组41例,每120小时更换1次吸痰管.比较更换后3组吸痰管前端培养的细菌定植率及呼吸机相关性肺炎（VAP）发生率.结果 3组导管前端细菌定植率分别为63.0％,71.2％,100％,差异有统计学意义（x^2 =6.182,P=0.023）；3组患者VAP发生率分别为7.4％,5.7％,4.9％,差异无统计学意义（x^2 =0.244,P＞0.05）.结论 每72小时更换1次密闭式吸痰管,既能保证患者的安全又能节省费用.Objective To study the reasonable replacement time for closed suction tube.Methods Totals of 147 patients who had artificial airway for mechanical ventilation and closed suction tube for aspiration of sputum were randomly divided into 3 groups：Group A of 54 cases with replacement time of 24 hours,Group B of 52 cases with replacement time of 72 hours,and Group C of 41 cases with replacement time of 120 hours.Rates of bacterial colonization cultured in closed sputum aspirator tip and incidence rate of VAP were compared between three groups.Results The rate of bacterial colonization cultured in closed sputum aspirator tip in three groups was respectively 63.0%,71.2% and 100%,and there was statistically significant difference （x^2 =6.182,P =0.023）.The incidence rate of VAP in three groups was respectively 7.4%,5.7%,4.9%,there was no statistically significant difference （x^2 =0.244,P 〉 0.05）.Conclusions Replacement of closed suction tube every 72 hours can ensure patients＇ safety as well as save the cost.
