Dexamethasone Versus Ondansetron in Preventing Postoperative Nausea and Vomiting In Laparoscopic Surgery
Keywords:Laparoscopic Cholecystectomy, Postoperative Nausea and Vomiting (PONV)
Objective: To compare the efficacy of dexamethasone 8mg versus ondansetron 4mg in preventing postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy
Methodology: This quasi-experimental study was conducted at the Department of Anaesthesia and Intensive Care, Holy Family Hospital from 29th July 2018 to 28th January 2019. Anesthesia was induced with propofol (2mg/kg IV) and Atracurium (0.5 mg/kg IV) was given to facilitate tracheal intubation. Nalbuphine (0.2mg/kg) was used as analgesic.Patients were randomly divided into two groups. Patients in Group A received 4mg ondansetron at end of surgery and Group B received 8mg dexamethasone at induction.
Results: A total of 90 patients were included according to the inclusion criteria of the study. The mean age (years) in the study was 37.11+10.60 years. Frequency and percentage of nausea (up to 24 hours) among both the groups was 28 (62.2) and 28 (62.2) respectively (p-value = 1.0) while the frequency and percentage of vomiting (within 24 hours after extubation) was 28 (62.2) and 27 (60.0) respectively (p-value = 0.829)
Conclusion: The study concluded that there was no significant difference dexamethasone and ondansetron in preventing postoperative nausea and vomiting.
