Umbilical line

A medical device used in neonatal care

An umbilical catheter in use

An umbilical line is a medical device used in neonatal care for the administration of fluids, medications, and for monitoring blood pressure in newborns. It is inserted into the umbilical cord of a newborn infant, which provides direct access to the circulatory system.

Types

There are two main types of umbilical lines: the umbilical arterial catheter (UAC) and the umbilical venous catheter (UVC).

Umbilical Arterial Catheter (UAC)

The UAC is inserted into one of the two umbilical arteries. It is primarily used for monitoring blood pressure and obtaining blood samples for blood gas analysis. This allows for continuous monitoring of the infant's cardiovascular system without repeated needle sticks.

Umbilical Venous Catheter (UVC)

The UVC is inserted into the umbilical vein. It is used for the administration of intravenous fluids, medication, and parenteral nutrition. It can also be used for exchange transfusions in cases of severe jaundice or hemolytic disease of the newborn.

Procedure

The insertion of an umbilical line is a sterile procedure performed by a trained healthcare professional. The umbilical stump is cleaned, and the catheter is carefully inserted into the appropriate vessel. The position of the catheter is confirmed by X-ray to ensure proper placement.

Indications

Umbilical lines are indicated in newborns who require intensive monitoring and treatment, such as those with respiratory distress syndrome, sepsis, or congenital heart disease. They are also used in premature infants who need prolonged intravenous therapy.

Complications

While umbilical lines are generally safe, they can be associated with complications such as infection, thrombosis, and vascular injury. Proper technique and monitoring are essential to minimize these risks.
