A First Evaluation of OMNI®, A New Device for Continuous Renal Replacement Therapy

Background: Omni((R)) (B. Braun, Germany) is a new-generation, continuous renal replacement therapy (CRRT) machine designed to improve user interface, minimize downtime and optimize renal dose delivery. It was never tested in humans. Methods: We used Omni((R)) to provide CRRT in 10 critically ill patients. We collected therapy data, metabolic parameters and evaluated user's satisfaction with a survey. Results: CRRT was delivered using Omni((R)) in CVVH-heparin (6 patients) and CVVHD-citrate (4 patients) modes for a total duration of 617.7 h. No adverse event was observed. The mean filter life was 22.8 (CVVH-heparin) and 33.5 (CVVHD-citrate) h. Alarms-related downtime corresponded to 5.9% of total therapy time. Delivered renal dose was 96.6% of prescribed. Satisfactory metabolic control and fluid removal were achieved. Overall, users evaluated interface, design and usability as excellent. Conclusion: CRRT in CVVH-heparin and CVVHD-citrate modes was provided using Omni((R)) in a safe and efficient way for 10 critically ill patients.
