Positive Affirmations and Preoperative Anxiety

This study is a prospective, quasi-experimental design using a convenience sample. This study will include patients who are having total knee or total hip replacement surgery. Participants will be invited to complete an anxiety scale at the conclusion of the total joint replacement (TJR) education class, listen to a guided imagery and positive affirmations recording once/day for three days prior to surgery, beginning on the third day before surgery and continuing to the day before their scheduled surgical procedure, listen to positive affirmations the morning of surgery in the preop area, and then complete an anxiety scale before entering the operating room.

Aromatherapy in Reducing PONV for Total Joint Replacement Patients

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.
