【摘要】目的：探讨危重症新生儿脐静脉置管时长对并发症的影响。方法：以涟水县人民医院2021年2月—2023年6月收治的40例危重症新生儿作为本次研究对象，均接受脐静脉置管，根据置管时长不同分为两组，对照组(20例)置管时长≤7d，观察组(20例)置管时长>7d，观察且记录两组危重症新生儿静脉营养时间、足量喂养时间及住院总时间，统计两组患儿撤管后3d出现感染的概率及住院期间出现并发症的概率。结果：观察组危重症新生儿静脉营养时间、足量喂养时间及住院总时间与对照组相比无统计学差异(P>0.05)；两组危重症新生儿撤管后3d出现感染的概率及住院期间出现并发症的概率比较无统计学差异(P>0.05)。结论：危重症新生儿接受脐静脉置管时，时间超过7d并不会明显增加并发症，因此可根据新生儿具体情况适度延长置管时间，以保障营养支持。

    【Abstract】Objective：To explore the impact of the duration of umbilical vein catheterization on complications in critically ill newborns. Methods：Forty critically ill newborns admitted to Lianshui County People’s Hospital from February 2021 to June 2023 were selected as the study subjects，all of whom received umbilical vein catheterization.They were divided into two groups based on the duration of catheterization.The control group (20 cases) had a catheterization duration of≤ 7 days ......
