IMPACT OF AROMATHERAPY ON POST-OPERATIVE DEPRESSION IN PATIENTS UNDERGONE CORONARY ARTERY BYPASS GRAFT SURGERY

Abstract

Objectives: The objective of the current study was to compare the effect of aromatherapy with lavender and damask rose on depression in patients after coronary artery bypass graft surgery (CABG).

Methodology: In this randomized clinical trial study, 97 patients undergoing CABG were randomly assigned to interventions or control groups. This study was performed in Guilan province during 2017-2018. The intervention groups were further divided into two groups of lavender and damask rose. These patients randomly before bedtime, at night from 9.00 p.m. to 11:00 p.m., for five nights. The control group got routine nursing care in consistency with the hospital procedure. The data were achieved through demographic- clinical and Beck Depression inventory questionnaires.

Results: During the five-night intervention period, showed that the overall mean of depression of lavender, damask rose and control groups before the intervention were 32.5, 20.47, and 26.48, respectively, and after the intervention were 29.92, 18.66, and 25.42, respectively. The mean score of depression after intervention did not differ significantly between the three groups (p-value=0.47). The results showed that the comparison of the mean score of depression in both groups of damask rose and lavender before and after the intervention was significantly different (p-value=0.05 and p-value=0.000 respectively).

Conclusion: Aromatherapy with damask rose essential oil and lavender had a positive effect on relieving postoperative depressive symptoms. However, no superiority was found between the two intervention groups in terms of effectiveness.
