剖宫产术后3种拔除尿管方法的比较

目的：观察比较剖宫产术后三种放尿方法对患者的影响。方法：选取170例剖宫产术后留置尿管的产妇随机分为三组：个体放尿组80例，液体余量组50例，传统放尿组40例。分别观察三组患者拔除尿管后第一次排尿情况。结果：个体放尿组首次排尿量分别多于液体余量组（t=3.24，P <0.01）、传统放尿组（t=7.05，P <0.01），个体放尿组首次顺利排尿成功率100%，明显高于其余两组（分别为96%、63%，P<0.05），同样，个体放尿组拔除尿管时间明显早于另两组，其差异具有统计学意义；三组尿路感染发生率分别为个体放尿组5%，液体余量组12%，传统放尿组33%，具有显著差异。结论：剖宫产术后采用个体放尿法可以尽早拔除尿管、促进产妇术后恢复，具有积极的临床意义。

A Study on three patterns of catheter removal after cesarean section

Objective To investigate the influence of three patterns of removing catheter on postcesarean patients. Methods All 170 patients after cesarean section were randomized into three groups: individual group, liquid amount group and traditional group. Observe and compare the first urination of three groups respectively after removing catheter. Results The first urine amount of individual group was more than that of liquid amount group and traditional group. The efficiency of individual group was 100% which was obviously higher than other two groups. The time of removing catheter in individual group was sooner than others. The incidence of urinary infection of individual group was 3.8% and was obviously less than liquid amount group (12.0%) and traditional group (12.0%). Conclusions The individual pattern is useful to remove catheter earlier and improve the patients recover. So its clinical application has a positive significance.
