摘要
目的规范留置导尿及其护理过程,降低留置导尿感染率。方法将73例留置导尿患者按住院号单、双分为对照组(38例)和观察组(35例),对照组按无菌操作原则置尿管,置管后以常规方法进行护理;观察组应用6Sigma改进模式及失效模式测量、分析留置导尿管感染主要原因,改进置管及置管后护理操作流程。结果留置导尿的第5、7天,观察组尿道口有菌率显著低于对照组(P<0.05,P<0.01);两组中段尿、导尿管和集尿袋接口处有菌率比较,差异无显著性意义(均P>0.05)。结论应用6Sigma方法系统分析留置导尿感染原因准确,采取的控制感染措施能有效降低留置导尿感染风险。
Objective To optimize the catheterization procedures and reduce the infection rate of indwelling urethral catheterization. Methods Totally 73 patients with indwelling catheter were divided randomly into a control group （38 cases） and an observation group （35 cases）. In the control group, catheter was inserted by using the aseptic technique and the patients were subjected to the routine nursing care. In the observation group, six sigma model was used to measure and analyze the reasons of infection from indwelling urethral catheterization, and to optimize the catheterization procedures and nursing care after catheterization. Results On the fifth and seventh day after catheterization, the rate of bacterial growth at urethral orifice in the observation group was significantly lower than that in the control group （P〈0.05 ,P〈0.01）. There was no significant difference in the rate of bacterial growth in urine culture between the observation group and the control one （P〉0.05 for all）. Conclusion Six sigma model was accurate in analyzing the reasons of indwelling urethral catheterization and the measures controlling infection were effective.
