Background: Respiratory and renal insufficiencies are common dysfunctions during post-liver transplantation period that increase post-operative mortality and morbidity rates. Intra-operative fluid therapy is an important factor associated with pulmonary and renal insufficiency.

Objective: To evaluate the relation between intra-operative fluid therapy and early renal and respiratory insufficiency after liver transplantation.

Methods: In this randomized clinical study, 67 adult patients with end-stage liver disease who underwent orthotopic deceased donor liver transplantation were randomly allocated into two groups. The restricted fluid group, which received a controlled fluid administration of normal saline, 5 mL/kg/hr during anesthesia, and non-restricted fluid group received a controlled infusion of normal saline 10 mL/kg/hr during anesthesia. Early post-operative respiratory and renal insufficiency in both groups were assessed. The patients were monitored during the three stages of liver transplantation for their hemodynamic indices. The trial is registered with the Iranian Randomized Clinical Trial Registry, number IRCT2013101811662N4.

Results: The baseline demographic and clinical characteristics were similar in both studied groups. The prevalence of respiratory insufficiency in the non-restricted fluid group (15%) significantly (p=0.01) higher than that in the restricted fluid group (0%). The post-operative mean±SD serum creatinine was 1.0±0.1 mg/dL in the non-restricted fluid group and 1.1±0.2 in the restricted fluid group (p=0.43). No patients in the studied groups required post-operative continuous renal replacement therapy.

Conclusions: Restricted crystalloid fluid administration during orthotropic liver transplantation though decreased post-operative chance of pulmonary insufficiency, did not increase renal dysfunction.
