导尿管伴随性尿路感染及其防治

The clinical observation of catheter-associated urinary tract infection

为探讨导尿管伴随性尿路感染（UTIc）的发生、发展规律及防治措施，对57例留置导尿管患者随机分组进行观察，具体方法是隔日收集尿液送细菌培养，当尿培养细菌数＞105／ml时定为尿路感染。结果3组患者随插管时间的延长，尿培养细菌阳性率逐日增加．3组间相应无效的细菌感染率有显著性差异（P＜0．05）．认为全身应用有效抗生素配合0．1％新洁尔灭定时冲洗导尿管并清除尿道口分泌物，可延缓UTIc的发生，对短期留置导尿管的患者，此法是一种较好的预防感染的方法，但对长期留置导尿管而发生感染的患者仍难以奏效．

For studving the pathogenesis and dereloping rule of catheter-associated urinarytract iofection (UTIc), 57 cases of patients with indwlling urethral catheter were grouped into non-antibiotic,antibiotic and antibiotic with wasbo groups. The urine bacterial culture wes carredout in these patients at every other day. The total number of bacteria of >10 5/ml regarded as urinary infection. Following the increasing tha of indwelling urethral catheter, the positive rate of urine bacteria culture was increasing for all the three groups. The urinary infective rate of corresponding days among the three groupes was singhficant difference (P<0.08). For the short timeof indwelling catheter patients, the antibiotic with 0. 1% bromogeramine washing was a good method for delafor UTIc occurrence,but for the patientg of long time indwelling catheter, it was not effcient.
