Comparison effect of Lavender Oil Inhalation and Tea on Sleep Quality, Fatigue, and Pain in Hemodialysis Patients: A Randomized Clinical Trial

Abstract

Background & Aim: The pain of arteriovenous fistula, fatigue and sleep disturbances are common problems in hemodialysis patients. Using lavender products can help reduce these problems. This study aimed to comparison the effects of lavender aromatherapy and lavender tea consumption on reducing pain and fatigue, as well as improving sleep quality in HD patients.

Methods and Materials: This study is a randomized clinical trial without blinding conducted at the Dialysis Center in Tabriz University of Medical Science from May to December 2022. Random allocation was done by randomizing the moved blocks. HD patients were allocated to one of the three study groups: control (n=30), lavender inhalation (n=30), and lavender tea (n=30). At the baseline and the end of the study, Participants' sleep quality with PSQI, fatigue with FSS, and pain of needle insertion in arteriovenous fistula with Vas scale were assessed. The data analysis was performed using SPSS software The Analysis of covariance (ANCOVA) test was used to compare the mean of variables between the study groups.

Results: The results showed that the scores of pain, fatigue and sleep quality after the intervention were statistically significant (P < 0.05) compared to before in the lavender tea group and lavender aromatherapy group; but in the control group there was no statistically significant difference (P < 0.05). Also, no statistically significant difference was observed between the lavender tea group and lavender aromatherapy group regarding the scores of sleep quality (P=0.428), fatigue (P=0.570), and pain (P=0.997).

Participants in the lavender tea group and lavender aromatherapy group had a lower score of subjective sleep quality (P<0.001), sleep latency, sleep duration, use of sleep medication, day time dysfunction (P for all <0.001), sleep disturbances (P=0.035), Total score of PSQI (P<0.001), fatigue (P<0.001), and pain (P<0.001) following the intervention compared to the control group. Following the intervention,

Conclusions: The findings of this study showed that the effects of lavender on the nervous system can be useful in improving the problems of dialysis patients, such as sleep quality, fatigue, and pain caused by needle insertion.
