【摘要】 脐静脉置管术在早产极低出生体重儿已广泛应用,但脐静脉置管在为早产儿建立"生命通道"的同时,也可能引起各种导管相关性并发症,甚至造成早产儿意外死,并发症的发生与导管尖端定位不准确及使用过程发生移位密切相关,目前缺乏导管有效随访及维护的可行方法,近年来随着床边重症B超的引入,床旁超声在早产儿脐静脉导管的定位及随访中具有良好的应用价值和前景。更多还原

【Abstract】 Umbilical vein catheterization has been widely used in premature infants with very low birth weight; however, while establishing a "life channel" for premature infants, it may also bring about various catheter-related complications, and even lead to accidental death of premature infants. The occurrence of complications is closely related to the inaccurate localization of catheter tip and the displacement of catheter tip, and there is a lack of feasible methods for effective follow-up and maintenance of catheters. In recent years, with the introduction of bedside B-ultrasound for severe cases, bedside ultrasound has a good application value and prospect in the localization and follow-up of umbilical vein catheters in premature infants.更多还原
