The study concluded that midazolam did not show a significantly different frequency of PONV compared to a combination of dexamethasone and ondansetron. Patients in both groups experienced similar rates of post-operative nausea and vomiting.
Background Midazolam reduces post-operative nausea and vomiting (PONV) when compared to a placebo or when used as an adjuvant to other antiemetics. The present study was designed to compare midazolam with a combination of dexamethasone-ondansetron in preventing PONV. Methods One hundred and twenty patients undergoing laparoscopic surgeries having 2 or more risk factors for PONV (simplified Apfel score) were randomised into 2 groups of 60 each. Patients in group D received 8-mg dexamethasone and 4-mg ondansetron for PONV prophylaxis while those in group M received 2-mg midazolam towards the end of surgery. The proportion of patients (frequency) who had PONV, post-operative nausea (PON) and post-operative vomiting (POV) was noted over 24 hours over the following intervals: 0-2 hours, 2-24 hours and 0-24 hours. Results The frequency of PONV at 24 hours in group D and group M was 30% and 33.3% respectively and was not significantly different (P = .70). There was no difference in the time to achieve post-anaesthesia discharge score of >= 9 between the two groups {5 minutes (5, 5) in group D; 5 minutes (1.25, 5) in group M, P = .48}. Ten patients in group D and 11 in group M required a rescue antiemetic over 24 hours (P = .81). The frequency of PON, POV and PONV as well as the median PONV score was similar at all time periods. Conclusion Midazolam does not result in significantly different frequency of PONV than a combination of dexamethasone-ondansetron.
