The Relationship of Developing Metabolic Acidosis With Antiepleptic Drugs in Craniotomy Operations

The base deficit values in the preoperative, intraoperative and postoperative blood gases taken from the patients and the presence and severity of metabolic acidosis were evaluated. Metabolic acidosis severity was defined by base deficit levels: mild from -3 to -5, moderate from -5 to -10, and severe metabolic acidosis below -10.
