Background: Fluid management during intracranial surgery is an important concern. The type of fluid used can have biochemical and metabolic effects during intraoperative management. However, it is yet to be known whether biochemical and metabolic effects have an influence on the clinical outcome of a patient. Objective: A prospective evaluation of the effects of normal saline (NS), Ringer's lactate (RL), and a combination of NS and RL on the biochemical, metabolic, and clinical outcomes in patients undergoing intracranial tumor surgery was carried out. Materials and Methods: Ninety patients undergoing elective intracranial tumor surgery were randomized to receive NS, RL, or a combination of NS and RL. The biochemical and metabolic parameters were studied at different time points in the intraoperative and postoperative period. The hemodynamic parameters, brain relaxation score at the time of bone flap elevation, postoperative complications, and the duration of hospital stay were the clinical outcome variables of our study. Results: The use of NS was associated with hyperchloremic metabolic acidosis and ionic hypocalcemia. RL caused significant hyponatremia and increase in serum lactate levels. The combination of NS and RL has least influence on biochemical and metabolic parameters. The effects of three fluids were similar on the hemodynamics, brain relaxation score, as well as on postoperative complications and the duration of postoperative hospital stay. Conclusion: There are variable effects of NS, RL, or its combination on the biochemical and metabolic parameters in patients undergoing intracranial tumor surgery. However, the clinical outcome of the patients remains similar.
