In the stable preterm newborn, a single lumen umbilical venous catheter (UVC) can be positioned at birth for intravenous hydration and parenteral nutrition; after the first few days, it will be necessary to assess whether the venous access is needed for a limited period (< 14 days) or longer (> 14 days). In the first case, it will be sufficient to plan the positioning of an epicutaneous-caval catheter (ECC); in the second case, it will be appropriate to insert an ultrasound-guided central venous access (CICC or FICC).
In the acutely ill newborn with a severe pathology already evident at birth, a double lumen umbilical venous catheter (UVC) is usually recommended; after few days, the UVC will be removed and replaced with an ultrasound guided central venous access (CICC or FICC).
