Introduction:
Umbilical venous catheters (UVCs) are essential in neonatal intensive care, yet blind insertion techniques remain common and increase the risk of malposition and liver injury. This study evaluated whether real-time ultrasound guidance improves UVC placement efficiency and safety.
Methods:
We retrospectively analysed 305 neonates who underwent ultrasound-guided UVC placement between July 2023 and January 2025 in a tertiary neonatal unit. The primary outcome was successful tip placement in the subdiaphragmatic vestibule; the secondary outcome was acute catheter-related liver injury.
Results:
Correct catheter placement was achieved in 86.56% of cases, with a gradual improvement from 83.81% to 89.12% over time. Only one hepatic haematoma was observed, and no other acute complications occurred.
Discussion:
Real-time ultrasound guidance significantly enhances the accuracy and safety of UVC insertion in neonates, minimising hepatic injury risk. Further research should assess its role in prolonged catheter monitoring.
