【摘要】 在76例患者中,研究了消毒剂密封式引流(UASD)预防留置导管性尿路感染的效果。发现留置导管后尿无菌日,UASD组(40例)为13.7±9.2(5—43)日,开放引流组(36例)为5.4±3.2(1—13)日,P<0.0001。置管后2日内两组尿无菌率无差异(P<0.05),3、7、11、14日尿无菌率(％),UASD组为100.0、95.0、75.0、68.4,开放引流组为88.9、27.8、10.5、0,P<0.05～0.0001。本研究表明,UASD是一种简便而有良好预防感染效果的引流方法。更多还原

【Abstract】 The preventive effect of under-antiseptic seal drainage(UASD)on catheter-associated urinary tract infection was studied in 76 patients whose urine cultures were negative prior to catheterization. Catheters were introducted into the urinary tracts in all patients for periods of >7 days. The average period for which urine was kept sterile was 13.7±9.2(5-43) days in UASD group (40 cases),and 5.4±3.2 (1-13) days in open drainage group (36 cases),P<0.0001·The uriue steritily rates (%)3, 7, 11 and 14 days after indwelling catheter were 100.0,95.0,75.0 and 68.4 respectively in UASD group;and 88.9,27.8,10.5 and 0 in open drainage group, P<0.05-0.0001 . The results suggest that UASD is a convenient and efficacious drainage method in preventing catheter-associated infection.更多还原
