Introduction: The current methods for estimating umbilical venous catheter (UVC) insertion depth, including the umbilical to nipple (Gupta) and the birth weight-based (modified Shukla) formula, have varying accuracy rates. Objectives: To compare the accuracy of UVC insertion length using the birth weight-based formula versus the surface measurement formula in determining the optimal UVC tip position. Methods: A multicenter randomized clinical trial was conducted in the neonatal intensive care units (NICUs) of the Second Cluster in Al Riyadh (AL Yamama Hospital and King Fahad Medical City), King Salman Armed Forces Hospital in the Northwestern Region, Tabuk City, Saudi Arabia. Neonates requiring UVC insertion during their NICU admission were randomly assigned to one of two formulas: 1) the umbilicus to nipple distance in centimeters minus 1 (UN - 1) or 2) the modified Shukla weight-based formula in centimeters (3 Ă— birth weight in kg + 9, divided by 2) to estimate the pre-insertion UVC depth and to determine the UVC tip position anteroposterior and lateral thoracoabdominal radiographs were taken and reviewed by a neonatologist, who was blinded to the group assignments. Data analysis was conducted using appropriate statistical methods, ensuring adherence to ethical standards.
