Abstract :
Introduction: Laparoscopic cholecystectomy is associated with an appreciably high rate of postoperative nausea & vomiting (PONV) which is considered as a reason of patient’s delay in discharge and disability aggravation. This study was designed to compare the effectiveness of Ondansetron, Dexamethason and Ondansetron plus Dexamethasone as an antiemetic prophylaxis for preventing PONV in patients after laparoscopic cholecystectomy.
Methods: In this randomised double blind study, 153 patients of both sexes of ASA I and II aged between 16 to 60 yrs received 4 mg Ondansetron (Group O, n = 50), 8 mg Dexamethason (Group D, n =51) or Ondansetron 4 mg plus Dexamethasone 8 mg (Group OD, n=52) intravenously immediately before induction of anaesthesia. Perioperative care was standardised in all patients. Patient was then observed for 24 hours postoperatively for any episode of PONV and any adverse effects of the study drugs.
Results: A complete response (defined as no PONV and no need for another antiemetic) was achieved in 62% of the patients receiving Ondansetron, 64.7% of the patient receiving Dexamethasone and in 84.6% of patients receiving Ondansetron plus Dexamethasone (P
