摘　　要：目的探讨不同膀胱冲洗频率对长期留置导尿产妇尿路感染的影响,为降低尿路感染率提供依据。方法选取医院2010年1月-2014年1月产科需长期留置导尿的产妇300例,根据随机数表法将其分为Ⅰ、Ⅱ、Ⅲ、Ⅳ组,每组各75例;产妇膀胱冲洗频率Ⅰ组每日2次、Ⅱ组每日1次、Ⅲ组每周2次、Ⅳ组为非冲洗组,每组膀胱冲洗方法均相同,留置尿管后于第3、7、14、21天进行中段尿培养检查,并统计4组产妇尿路感染发生率;采用SPSS18.0软件进行统计分析。结果第3、7、14、21天时Ⅰ组产妇尿路感染率分别为2.67%、10.66%、16.00%和36.00%;Ⅱ组分别为0、9.33%、21.33%和34.67%;Ⅲ组分别为0、2.67%、9.33%和17.33%;Ⅳ组分别为0、10.66%、24.00%和42.67%;治疗后第7、14、21天Ⅲ组产妇尿路感染率显著低于其他3组,而不进行膀胱冲洗的Ⅳ组患者明显高于其他组,差异有统计学意义(P<0.05)。结论每周两次膀胱冲洗频率可显著降低长期留置导尿产妇尿路感染率,减少细菌定植。OBJECTIVE To observe the effect of frequency of bladder irrigation on urinary tract infections in puerpera with long-term indwelling catheter so as to reduce the incidence of urinary tract infections.METHODS A total of 300 puerpera who were treated with long-term indwelling catheter in department of obstetrics from Jan 2010 to Jan 2014 were enrolled in the study and randomly divided into the group Ⅰ,Ⅱ,Ⅲ,and Ⅳ,with 75 cases in each.The groupⅠ group was treated with the bladder irrigation,twice a day;the groupⅡ was treated with the bladder irrigation,once a day;the group Ⅲ was treated with bladder irrigation,twice a week;the group Ⅳ was not treated with bladder irrigation.All of the groups were treated with the same bladder irrigation.The midstream urine specimens were respectively cultured after the catheter indwelling for 3,7,14,and 21days;the incidence of urinary tract infections was observed and compared among the 4groups,and the statistical analysis was performed with the use of SPSS 18.0software.RESULTS The incidence rate of urinary tract infections was 2.67%in the groupⅠon Day 3,0in the groupⅡ,0in the groupⅢ,0in the groupⅣ;the incidence rate of urinary tract infections was10.66%in the groupⅠon Day 7,9.33%in the groupⅡ,2.67%in the groupⅢ,10.66%in the groupⅣ;the incidence rate of urinary tract infections was 16.00%in the groupⅠon Day 14,21.33%in the groupⅡ,9.33%in the groupⅢ,24.00%in the groupⅣ;the incidence rate of urinary tract infections was 36.00%in the groupⅠon Day 21,34.67%in the groupⅡ,17.33%in the groupⅢ,42.67%in the groupⅣ.The incidence rate of urinary tract infections of the groupⅢwas signific antly lower than that of other three groups on Day 7,14,or 21 of treatment,however,the incidence rate of urinary tract infections of the group signific antly reduce the incidence rate of urinary tract infections in the puerpera with longterm indwelling catheter and prevent the bacterial colonization.Ⅳ was significantly higher than that of other three groups（
