We used acetated Ringer (AR) and lactated Ringer (LR) solutions as an intraoperative fluid during hepatectomy and evaluated their effects on intraoperative and postoperative hemodynamics, metabolism, blood gas and renal as well as liver functions. Twenty patients scheduled for hepatectomy were divided into two groups according to the type of infused solution, AR or LR. The infusion rate was 15 ±2 ml · kg-1 · min-1 with the first 500 ml and thereafter reduced to 10 ± 2 ml · kg-1 · min-1. Intraoperative serum lactate levels increased significantly in both groups. However, the level of lactate in the LR group (48.6 ± 16.4 mg · dl-1) was significantly higher than in the AR group (29.1 ± 14.3 mg · dl-1) at the end of the operation. D-lactate level was significantly higher in the LR group than in the AR group during the operation. Although acetate level increased significantly during the operation in the AR group, it decreased to the normal range at the end of the operation. There were no significant differences in the other parameters between the two groups. These results suggest that AR may be more useful in hepatectomy than LR as an intraoperative fluid.
