Summary

This study aims to evaluate and compare the effectiveness of intravenous haloperidol and ondansetron in preventing postoperative nausea and vomiting (PONV) in patients undergoing surgery with subarachnoid block (spinal anesthesia). PONV is a common postoperative complication that can delay recovery, cause patient discomfort, and increase healthcare costs.

In this randomized, double-blind, prospective trial, eligible male patients aged 18-60 years undergoing elective surgeries under regional anesthesia were enrolled. Participants were assigned to receive either haloperidol or ondansetron during the intraoperative period. Both drugs are widely used antiemetic agents: haloperidol is a dopamine receptor antagonist, and ondansetron is a serotonin 5-HT3 receptor antagonist.

The primary objective was to assess the incidence of PONV within 24 hours after surgery. Results showed that haloperidol significantly reduced PONV incidence compared to ondansetron, with minimal adverse effects. The study suggests that intravenous haloperidol may be a cost-effective and well-tolerated alternative to ondansetron for PONV prevention in selected patients undergoing spinal anesthesia.

Conditions

  • Postoperative Nausea and Vomiting (PONV)
  • Subarachnoid Block
  • Spinal Anesthesia

Interventions

DRUG

Haloperidol

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.

DRUG

Ondansetron 4mg

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.
