Summary

This study tested whether a nausea relief inhaler (aromatherapy with essential oils) can reduce post-operative nausea and vomiting in 50 adults after bariatric surgery. The goal was to see if the inhaler could lessen the need for additional nausea medication and improve patient satisfaction. Researchers tracked medication use and patient distress in the first 24 hours after surgery.
