Comparison of Haloperidol and Ondansetron in Reducing Postoperative Nausea and Vomiting in RA-SAB Patients

A single dose of haloperidol (1-2 mg) was administered intravenously during the intraoperative period to patients undergoing surgery under subarachnoid block (RA-SAB). This intervention was designed to evaluate its effectiveness in preventing postoperative nausea and vomiting (PONV). Both patients and providers were blinded to the assignment.

A single dose of ondansetron (4 mg) was administered intravenously during the intraoperative period to patients undergoing surgery under subarachnoid block (RA-SAB). This intervention served as the active comparator to haloperidol in evaluating the prevention of postoperative nausea and vomiting (PONV). The study was conducted in a double-blind manner.
