INTRODUCTION: The lack of peritoneal dialysis (PD) catheters designed explicitly for neonates creates significant challenges in the provision of neonatal PD. High resource settings can circumvent this limitation by resorting to alternative extracorporeal dialysis methods. However, in low-resource settings, PD remains the preferred dialysis modality, and the use of off-label catheters for PD results in complications such as omental wrapping and occlusion. This study introduces a novel catheter design featuring a multi-diameter side port configuration and a helical geometry.
METHODS: We employed numerical simulations to identify an optimal multi-diameter side port configuration, to address fluid dynamic issues that lead to catheter occlusion and omental wrapping. Following the simulations, we experimentally evaluated the catheter's performance in a series of benchtop tests designed to simulate physiological conditions encountered in neonatal PD.
RESULTS: Our experimental evaluations demonstrated that the helical catheter outperforms commonly utilized pigtail catheters with same-sized diameter side ports by consistently achieving superior drainage efficiency during fibrin clot occlusion and omental wrapping tests.
CONCLUSION: The catheter is intended to be placed at the bedside to perform renal replacement therapy for neonates in low-resourced settings.
