Abstract

Background & Aim: Postoperative pain, anxiety and sleep disturbances are common among patients undergoing orthopedic surgery, often leading to increased physical complications and substantial healthcare costs. Given the rising interest in non-pharmacological methods such as aromatherapy, this study aims to investigate the effectiveness of lavender inhalation aromatherapy in alleviating pain, anxiety and enhancing sleep quality in patients post-orthopedic surgery. Methods & Materials: This randomized clinical trial was conducted in 2022 at a trauma center in Isfahan, involving 80 patients undergoing orthopedic surgery. Eligible patients were recruited through consecutive sampling and were randomly assigned to either the intervention group (n=40) or the control group (n=40). The intervention included inhalation of 100% pure lavender essential oil over a period of three days, while the control group received standard postoperative care. The study employed the Standard Spielberger anxiety questionnaires, the St. Marry’s Hospital Sleep Questionnaire (SMHSQ), and the Visual Analog Scale (VAS) for data collection. Data were analyzed using paired t-tests, independent t-tests, chi-square tests, and one-way repeated measures analysis of variance, utilizing SPSS software version 26. Results: Post-intervention analysis revealed statistically significant differences in the average scores of anxiety and sleep quality between the intervention and control groups (P<0.001). Additionally, the average pain scores exhibited significant differences at all time points across both groups (P<0.001). Conclusion: The findings show that lavender aromatherapy significantly reduces pain and anxiety while improving sleep quality in patients following orthopedic surgery. Given these positive effects, the integration of this cost-effective and easily accessible intervention is recommended as a complementary treatment, alongside conventional methods. © 2025 Elsevier B.V., All rights reserved.
