【摘要】 目的探讨留置尿管期间的消毒方法及与发生尿路感染的相关性。方法将80例留置导尿的患者随机分成两组,观察组应用0.5%碘伏棉球滑润尿管消毒会阴皮肤黏膜及消毒尿道外口及尿管的4～5cm,与常规应用无菌石蜡油润滑尿管,0.1%苯扎溴铵消毒会阴皮肤黏膜,常规温水清洁会阴及尿道外口进行比较,是否有利于预防尿路感染及留置尿管时间对菌尿发生率的影响。结果采用0.5%碘伏作会阴及尿道口消毒,使尿管留置时间相同者菌尿发生率明显下降(P<0.05),而随留置尿管时间增长,菌尿发生率上升。结论应用0.5%碘伏棉球润滑尿管和棉签擦拭尿道口及尿管近端4～5cm能有效地降低泌尿系感染的发生率。更多还原

【Abstract】 OBJECTIVE To investigate the disinfection method for indwelling urinary catheter and its correlation with the urinary infection.METHODS Eighty cases with indwelling catheter were randomly assigned to two groups.0.5% Polyvidone iodine(Iodophor)was used as lubricant and disinfectant in the experimental group.The control group received liquid paraffin and 0.1% benzalkonium bromide.RESULTS The incidence of urinary tract infections in the experiment group was significantly lower than that in the control group with the same indwelling time of catheter(P<0.05),the longer the indwelling time of catheter was,the more the incidence of urinary tract infections was.CONCLUSIONS The result suggested that 0.5% Polyvidone iodine used as lubricant and disinfectant effectively reduce the incidence of urinary tract infection in patients with indwelling catheters.更多还原
