Time to First Rescue Antiemetic With Ondansetron Plus Metoclopramide Versus Dexamethasone Plus Metoclopramide for PONV Prophylaxis in Laparoscopic Cholecystectomy
Sponsor: Faisalabad Medical University
Summary
The goal of this superiority randomized controlled trial (RCT) is to learn if one dual-drug arm increases patient comfort (time to needing rescue medication for nausea/vomiting) more effectively than the other in adults with Moderate-to-High PONV risk (Apfel score 2-4) undergoing elective laparoscopic cholecystectomy (gallbladder surgery). The main question this study aims to answer is: • Does Ondansetron plus Metoclopramide prolong time to first rescue antiemetic more than Dexamethasone plus Metoclopramide? Researchers will compare Group A (Ondansetron 4mg plus Metoclopramide 10mg IV) to Group B (Dexamethasone 8mg IV plus Metoclopramide 10mg IV) to see if Group A provides a longer time to first rescue medication. Participants will: * Receive their assigned, blinded drug group 5-10 minutes before general anesthesia induction. * Receive rescue Metoclopramide 10mg IV if they experience any vomiting or severe nausea * Be monitored for 24 hours post-surgery in the hospital * Report nausea severity at 2, 6, 12 and 24 hours post-surgery

Conditions
Interventions
ondansetron 4 mg
Ondansetron 4 mg IV administered as a single colorless syringe 5-10 minutes before induction of anesthesia for prevention of postoperative nausea and vomiting.
Dexamethasone (intravenous)
Dexamethasone 8 mg IV administered as a single colorless syringe 5-10 minutes before induction of anesthesia for prevention of postoperative nausea and vomiting.
Metoclopramide 10mg
Metoclopramide 10 mg IV administered as a single colorless syringe 5-10 minutes before induction of anesthesia as part of dual-agent PONV prophylaxis. Also used as rescue antiemetic (10 mg IV) if patient has vomiting or VRS \>4 for nausea.
