umbilical line
Catheter inserted through umbilical vessels for vascular access in newborns.
Full Definition
An umbilical line is a vascular access catheter inserted through the umbilical cord vessels, either the umbilical artery (UAC) or umbilical vein (UVC), in newborns. These lines provide reliable vascular access for blood sampling, medication administration, fluid delivery, and continuous blood pressure monitoring. Umbilical arterial catheters are typically positioned in the aorta for arterial access, while umbilical venous catheters terminate in the inferior vena cava or right atrium. These lines are particularly valuable in critically ill newborns who require frequent blood draws and continuous monitoring. Proper placement is confirmed by radiography, and lines require careful maintenance to prevent complications such as infection or thrombosis.
Usage
Usage note: May be specified as UAC (umbilical arterial catheter) or UVC (umbilical venous catheter); hyphenate when used as adjective.
