Could a common sedative stop post-surgery nausea?

This study tested whether adding a low dose of midazolam (a sedative) to the usual two-drug combination (dexamethasone and ondansetron) could better prevent nausea and vomiting after gynecologic laparoscopic surgery. 300 women aged 19–65 took part. Half received the standard two drugs plus a placebo, and the other half received the standard two drugs plus midazolam. The main goal was to see if fewer patients had significant nausea (score under 4 on a 0–10 scale) in the first 24 hours after surgery.
