目的分析探讨留置导尿相关尿路感染(CAUTI)问题的主要影响因素,寻找有效的预防措施。方法收集我院小儿泌尿外科于住院期间留置导尿患儿112例,监测疾病种类、留置管道类型、留置管道时间、术后应用抗生素种类、时间、拔除导尿管前尿常规中白细胞数、白细胞酶及尿培养结果8项指标,用logistics回归分析方法分析尿路感染的主要影响因素。结果术后插管时间越长,则尿培养结果为阳性的可能性越大(χ2=4.90,P<0.05)。疾病种类对CAUTI的影响也有差异性(χ2=6.09,P<0.05),余无显著差异性。结论在所监测的指标中,术后留置管道时间是可以控制的CAUTI的主要影响因素,要尽量缩短留置导尿时间,去除管道才能从根本上控制感染。
Objective To analyze and discuss the main influencing factors of CAUTI and find effective preventive measures. Methods 112 pediatric patients with urinary catheterization were collected during pediatric urology in our hospital. The types of diseases, the type of indwelling catheter, the length of indwelling catheter, the type and duration of antibiotics after operation, the number of leukocytes in urinary routine before catheter removal, Enzyme and urine culture results of eight indicators, the use of logistics regression analysis of urinary tract infection analysis of the main influencing factors. Results The longer the postoperative intubation time, the more likely the urine culture result was positive (χ2 = 4.90, P <0.05). The effects of disease types on CAUTI were also different (χ2 = 6.09, P <0.05), with no significant difference. Conclusion Among the monitored indicators, the time of postoperative indwelling catheter is the main factor of CAUTI that can be controlled. In order to shorten the catheterization time as far as possible, the removal of the pipeline can fundamentally control the infection.
