An umbilical catheter is a medical device that is inserted into the umbilical artery or vein of a newborn baby. It is used for various medical purposes, primarily in neonatal intensive care units (NICUs) and critical care settings. The umbilical catheter provides direct and convenient access to the baby's circulatory system for monitoring and administering medications or fluids. There are two main types of umbilical catheters: umbilical artery catheters (UACs) and umbilical venous catheters (UVCs).
Umbilical Artery Catheters (UACs): These catheters are inserted into the umbilical artery, which carries oxygenated blood from the placenta to the baby. The UAC allows for continuous monitoring of blood pressure and blood sampling to assess the baby's arterial blood gases, electrolyte levels, and acid-base balance. It is commonly used in critically ill newborns who require frequent monitoring and close management of their cardiovascular status.
Umbilical Venous Catheters (UVCs): These catheters are inserted into the umbilical vein, which carries deoxygenated blood from the baby back to the placenta. The UVC provides a route for administering medications, fluids, and parenteral nutrition directly into the baby's bloodstream. It is often used for delivering critical medications, such as antibiotics, vasopressors, or total parenteral nutrition (TPN), in newborns who have limited peripheral venous access or require long-term intravenous therapy.
The placement of umbilical catheters is typically performed by trained healthcare professionals using sterile techniques. The catheters are secured in place to prevent accidental dislodgment. Careful monitoring and regular assessment of the catheter site are essential to detect any signs of infection or complications.
It's important to note that the use of umbilical catheters is a specialized medical procedure and should only be performed by healthcare professionals with the appropriate training and expertise. The decision to insert an umbilical catheter is made based on the specific medical needs of the newborn and is usually reserved for critically ill infants who require intensive care and monitoring.
