About this study
This prospective observational cohort study aims to evaluate the association between menstrual phase (determined by postoperative serum progesterone levels), intraoperative anesthetic consumption, and the incidence and severity of postoperative nausea and vomiting (PONV) in female patients undergoing cholecystectomy. Intraoperative anesthetic requirements will be recorded, and postoperative nausea and vomiting will be assessed using standardized scoring systems.
