Anesthesia Management and Fluid Therapy in Right and Left Lobe Living Donor Hepatectomy

Objective: Right lobe living donor hepatectomy poses a greater risk for the donor in relation to blood loss. The aims of this study were to compare anesthetic and intraoperative fluid management in right and left lateral segment living donor hepatectomy. Patients and Methods: The anesthesia records of living donor hepatectomy patients were retrospectively reviewed. Donor age and weight, anesthesia time, central venous pressure, blood loss, blood product transfusion, intravenous fluids used, doses of furosemide, and urine output were compared and analyzed between groups using the Mann Whitney U test. Results: Forty-six patients underwent living donor left lateral segment hepatectomy (Group I); while 31 patients underwent right lobe hepatectomy (Group II). The mean blood loss in Group II was significantly higher compared to Group I (118 ± 81 mL vs 68 ± 64 mL), but clinically such amount of blood loss was not high enough to affect the hemodynamics. The fluid management was therefore not meaningfully different between the two groups. No blood transfusions or colloid infusions were required for either group. Urine output, hemoglobin changes, blood urea nitrogen, and serum creatinine pre- and postoperatively were not significantly different between groups. Conclusions: As long as blood loss is minimal, we found no difference in the anesthetic management and fluid replacements between right and left lateral segment living donor hepatectomy.
