What this trial studies

This study investigates the effectiveness of a nausea relief inhaler in reducing post-operative nausea and vomiting in patients undergoing bariatric surgery. Given that a significant percentage of these patients experience nausea and vomiting, the study aims to evaluate whether aromatherapy and essential oils can provide relief without the side effects associated with traditional medications. The research will involve patients aged 18 to 65 who meet specific eligibility criteria and will assess the inhaler's impact on patient satisfaction and mobility post-surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 who are scheduled for bariatric surgery and can attend a pre-operative class.

Not a fit: Patients with a BMI greater than 60, those on pre-operative nausea medication, or individuals with specific allergies or respiratory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance patient comfort and recovery after bariatric surgery.

How similar studies have performed: While the use of nausea relief inhalers has been studied in other surgical populations, this specific application in bariatric patients is relatively novel.
