Case in brief
This case series details the use of a 6 French Nuwellis® dual lumen extended length catheter (dELC) for umbilical venous access in four neonates requiring continuous kidney replacement therapy (CKRT). All placements were successful, with blood flow rates between 20-40 mL/min. Complications included one catheter with hub cracks and flow limitations in one patient, while two patients experienced no complications. Half transitioned to tunneled catheters post-therapy.
Diagnostic / clinical pearl
The Nuwellis® dELC may provide a safe and effective alternative for umbilical venous access in neonates requiring CKRT, potentially improving access options in this vulnerable population.
Why it matters
This case series highlights the potential for using umbilical venous access in neonatal CKRT, which is not widely practiced in the USA, suggesting a need for further investigation into its safety and efficacy.
