Effect of low-dose propofol infusion with sevoflurane versus propofol-only total intravenous anesthesia on postoperative nausea and vomiting in high-risk patients: a single-blind randomized controlled clinical trial

Key Points

• Postoperative nausea and vomiting rates are lower with low-dose propofol infusion combined with sevoflurane.
• A significant difference of 30% was observed in the reduction of nausea compared to propofol-only anesthesia.
• Randomized controlled trial with a single-blind design was used to evaluate the effects on high-risk patients.
• Findings support the use of combined anesthetic techniques to minimize postoperative complications.
