Summary

This study investigates the effectiveness of aromatherapy in reducing postoperative nausea and vomiting (PONV) among patients undergoing total joint replacement surgery, as these complications can lead to patient discomfort and prolonged recovery. It is designed as a randomized controlled trial involving 159 participants, who will be divided into three groups: an intervention group receiving aromatherapy patches (lavender-sandalwood or orange-ginger) plus standard care, a placebo group with a placebo patch plus standard care, and a control group receiving standard care alone. PONV will be measured using the Rhodes Index of Nausea, Vomiting, and Retching (RINVR) at baseline, 30 minutes after the intervention, and every 12 hours post-surgery. Additionally, patient satisfaction will be assessed through a 5-point Likert scale survey. The primary outcome of the study is the evaluation of RINVR scores, while the secondary outcome focuses on patient satisfaction levels. Data will be statistically analyzed using two-way ANOVA for repeated measures, with a significance level defined as p \< 0.05. The study aims to determine the viability of aromatherapy as a complementary treatment for PONV, potentially improving postoperative care, enhancing patient satisfaction, and offering a cost-effective alternative to conventional anti emetic treatments if proven effective.
