Umbilical and Peripheral Venous Catheter-Related Outcomes in Premature Neonates

Central venous catheters are essential but associated with complications in premature infants. We compared the short-term outcomes of umbilical venous catheter (UVC) versus peripherally inserted central catheter (PICC) as the initial postnatal primary venous access in preterm infants.

Preterm infants with a birth weight ≤ 1500 g within the first postnatal hours were included. Patients were randomly assigned to the UVC or PICC groups. Catheter insertion time, number of attempts, number of operators, duration of catheter use, reason for removal, and overall duration were recorded.

A total of 107 premature infants were included, with 63 receiving UVC and 44 receiving PICC. Nineteen infants who initially had UVC placement on day 1 required PICC placement on day 5. The number of attempts, number of operators, and insertion time were significantly higher in the PICC group compared with the UVC group (p < 0.001, p = 0.002, and p = 0.002, respectively). Catheter removal due to thrombosis or leakage occurred in 14.2% of UVC cases versus 40.1% of PICC cases (p = 0.002).

UVC placement appears to be superior to PICC as the first venous access in preterm infants during the early postnatal period. PICC placement may be less advantageous in the first days of life due to a smaller catheter diameter, technical difficulty, and longer insertion time.
