Background: Nurse fatigue can cause burnout, then it is effective on quality of patient care. So this study with the goal of determination of the effect of inhalation aromatherapy with lavender and Rose damascena essential oil on the fatigue of emergency nurses was accomplished. Method: This quasi-experimental study was done on 37 nurses working in emergency department which were selected based on convenience sampling method. The interventions were 2 minutes inhalation of distilled water in the first week, 2 minutes inhalation of pure lavender oil in the second week, and 2 minutes inhalation of pure Rose damascena oil in the third week. The tools were demographic questionnaire and Brief Fatigue Inventory which were filled before and after the interventions. Data analysis was done by SPSS version 20 and α =0.05 was considered. Results: Before the intervention, there was no significant difference among the means of fatigue rates in the three groups (P=0.856). But after the intrvention, a significant difference was seen among the means of fatigue rates inthe three groups (P=0.031). It showed that the means of fatigue rates in the lavender (36/5) and Rose damascena (42/2) groups were lower than that in the distal water group(47/3). There was no significant difference between the means of fatigue rates in the distal water group before and after the interventions. But there was a significant difference between the means of fatigue rates in the lavender group (36/5) (P≤0.001) and the Rose damascena group (42/2) (P≤0.001) before and after the interventions. There was no significant difference between the means of fatigue rates in the lavender and the Rose damascena groups (P=0.162). Conclusion: The fatigue rates of the nurses have reduced by inhalation aromatherapy with lavender and Rose damascena essential oils. So using these oils for lowering the nurses’ fatigue rates in work environments is recommended.
