目的 分析新生儿导尿管相关性尿路感染（CAUTIs）的影响因素。方法 回顾分析2012年1月至2021年 2月留置导尿新生儿的临床资料，根据是否发生CAUTIs分为CAUTIs组与非CAUTIs组，分析CAUTIs发生的影响因 素。结果 362例新生儿中，63例（17 . 4 %）发生CAUTIs。其中男38例、女25例，出生胎龄为37（36~40）周，出生体质 量为（2 . 82±0 . 79）kg。二分类logistic回归分析显示，留置尿管时间、置管次数是新生儿CAUTIs发生的独立危险因素 （P<0.05），而出生体质量、入院日龄、出生胎龄、导尿管口消毒护理次数是新生儿CAUTIs发生的独立保护因素（P<0.05）。 结论 减少早产、低日龄与低体质量儿留置导尿，缩短留置导尿时间与减少置管次数，增加导尿管口消毒护理是减少新生 儿CAUTIs的主要措施。

Objective To analyze the influence factors of neonatal catheter-associated urinary tract infection (CAUTIs). Methods The clinical data of neonates with indwelling catheterization from January 2012 to February 2021 were retrospectively analyzed. According to the occurrence of CAUTIs, they were divided into CAUTIs group and non CAUTIs group and the influence factors of CAUTIs were analyzed. Results The CAUTIs occurred in 63 (17.4%) of 362 neonates. There were 38 boys and 25 girls with gestational age of 37 ( 36 - 40 ) weeks and birth weight of ( 2 . 82 ±0 . 79 ) kg. Binary logistic regression analysis showed that time and frequency of indwelling catheter were independent risk factors for CAUTIs (P
