Time to First Rescue Antiemetic With Ondansetron Plus Metoclopramide Versus Dexamethasone Plus Metoclopramide for PONV Prophylaxis in Laparoscopic Cholecystectomy
Time-to-first-rescue Antiemetic With Ondansetron Plus Metoclopramide Versus Dexamethasone Plus Metoclopramide for PONV Prophylaxis in Laparoscopic Cholecystectomy: a Randomized, Triple-Blind, Superiority Trial
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

メジャーの説明 |
時間枠 |
|---|---|---|
|
Time to First Rescue Antiemetic (in minutes)
時間枠:First 24 hours after surgery (measured from the time of arrival to Post-anaesthesia care unit, PACU)
|
Time in minutes from patient arrival to Post-anaesthesia care unit, PACU (time zero) to administration of rescue metoclopramide 10 mg IV.
Rescue is given if patient experiences any episode of vomiting/retching or reports a nausea Verbal Rating Scale (VRS) score >4.
VRS scale is no nausea (0), mild (1-3), moderate (4-6), and severe (7-10).

First 24 hours after surgery (measured from the time of arrival to Post-anaesthesia care unit, PACU)

Number of Rescue Doses Required
時間枠:First 24 hours after surgery
|
Total number of rescue antiemetic (metoclopramide 10 mg IV) doses administered to each patient within the first 24 hours.

|
|
Incidence of PONV
時間枠:24 hours post-surgery
|
Proportion of patients experiencing any nausea (VRS >1) or any vomiting/retching episode within the first 24 hours post-surgery. Verbal Rating Scale (VRS) is a well established measurement scale with a total of 11 points where 0 = no nausea and 10 = worst possible nausea. |
24 hours post-surgery
|
|
Severity of Postoperative Nausea and Vomiting (RINVR Score)
時間枠:Measured at 2, 6, 12, and 24 hours post-surgery
|
Measured using the Rhodes Index of Nausea, Vomiting, and Retching (RINVR).
It evaluates 8 dimensions: frequency/duration/distress of nausea; frequency/amount/distress of vomiting; and frequency/distress of retching.
Total score range is 0-32, with 0 indicating no nausea, 1-8 mild, 9-16 moderate, 17-24 severe, and 25-32 great nausea.
The higher scores indicate worse PONV.
|
Measured at 2, 6, 12, and 24 hours post-surgery
|
|
Patient Satisfaction with Antiemetic Treatment
時間枠:At hospital discharge (approximately 24 hours post-surgery)
|
Patient-reported satisfaction measured on a 5-point Likert scale (Very Dissatisfied to Very Satisfied) at the end of hospital stay. Likert scale is a 5-point psychometric survey scale, with 1 indicating very disappointing and 5 indicating very satisfying. The higher the score, the better the treatment was. |
