Background: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright’s or Shukla’s formula is used to introduce the catheters. However, Shukla’s formula is associated with incorrect insertion, especially for newborns 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). Conclusions: We found 13% more correctly placed VUC using Wright’s formula. Moreover, Wright’s formula was 29% above Shukla’s VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.
