Revised UVC insertion formula

An observational (pre-post) study compared insertion of umbilical venous catheters using the Shukla formula ((3 x birthweight in kg + 9)/2)+1 cms to insertion using a formula where the 1 was not added, i.e., ((3 x birthweight in kg)+9)/2). The frequency of high insertion was lower with the new formula and more catheters were placed in the correct position on the first attempt. Overall, about 70% of UVCs were successfully placed.
