Restrictive Fluid Management In Liver Transplantation (REFIL)

Plain-language summary

Hypothesis: A Canadian multicentre clinical trial is feasible. Study Design: Multicenter internal pilot parallel arm randomized controlled trial. Study population: Patients with end-stage liver disease (ESLD) undergoing a liver transplantation, not meeting any exclusion criteria. Primary feasibility endpoint: An overall recruitment rate ≥ 4 patients/month across all four participating sites. Secondary feasibility endpoints: A protocol adherence \> 90%, a 30-day (or hospital discharge) and 6-month outcome measurement \> 90%, and a mean difference in total intraoperative volume received (crystalloids and colloids combined) \> 1000 ml between groups. Study intervention: Low splanchnic blood volume restrictive fluid management strategy (intervention). A phlebotomy, performed prior to dissection and transfused back after graft reperfusion, combined with a hemodynamic goal-directed restrictive fluid management strategy. Optimized cardiac-output liberal fluid management strategy (control) A hemodynamic goal-directed liberal fluid management strategy that optimizes cardiac output throughout surgery.
