Postoperative Nausea and Vomiting Clinical Trial
Official title:
Oral Dexamethasone at Night to Prevent Postoperative Nausea and Vomiting After Laparoscopic Cholecystectomy: A Protocol for Randomized Clinical Trial
Postoperative nausea and vomiting (PONV) are common complications after laparoscopic cholecystectomy. This study aims to evaluate the efficacy of the administration of prophylactic oral dexamethasone at night before surgery in preventing PONV after elective laparoscopic cholecystectomy.
Background: Postoperative nausea and vomiting (PONV) are common complications after laparoscopic cholecystectomy. This study aims to evaluate the efficacy of the administration of prophylactic oral dexamethasone 12 hours before induction of anesthesia in preventing PONV after elective laparoscopic cholecystectomy, as it reaches its peak effect at 2-12 hours and lasts for 72 hours after oral administration. Methods: This is a parallel, two-arm, randomized (1:1), controlled, single-center non-inferiority trial. Adults (≥18 years) with ASA physical status I-III scheduled for elective laparoscopic cholecystectomy will be eligible for inclusion. The participants will be randomized to receive either 8 mg of IV Dexamethasone at the time of induction of anesthesia or 8 mg of oral Dexamethasone 12 hours before induction of anesthesia. The primary outcome will be the incidence of postoperative nausea and vomiting. A total of 814 patients are intended to be recruited for this non-inferiority trial. Discussion: The current randomized trial is exploring the non-inferiority and feasibility of oral dexamethasone at night to reduce the PONV after laparoscopic cholecystectomy when compared to the standard of care - intravenous dexamethasone at the time of induction. Additionally, the investigators suppose oral dexamethasone at night is easier to administer, avoids polypharmacy at the time of induction of anesthesia, avoids the unpleasant sensation of intravenous injection, and is at a lower cost for a one-day surgery. ;
