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.
