A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial will enroll 159 adults undergoing total joint replacement and randomize them into three groups: aromatherapy patches plus standard care, placebo patch plus standard care, or standard care alone. Nausea and vomiting will be measured with the Rhodes Index of Nausea, Vomiting, and Retching at baseline, 30 minutes after the intervention, and every 12 hours after surgery. Patient satisfaction will be captured using a 5-point Likert scale, with primary analysis focused on RINVR scores and secondary analysis on satisfaction. The trial is conducted at Hong Kong Buddhist Hospital with collaborators from Queen Elizabeth Hospital.
