Abstract


Background: Most patients receiving nitroglycerin infusion experience some degree of headache. This study aimed to determine the effect of aromatherapy with lavender and valerian essential oil on the severity of headaches caused by nitroglycerin infusion, vital signs, and narcotic use in patients with coronary artery disease admitted to CCU wards. Materials and Methods: This three‑blind clinical trial was performed with the participation of 90 patients with consent. Patients were randomly divided into three groups (lavender, valerian, and control). Samples of lavender and valerian groups were inhaled cotton soaked in 3 drops of fragrance for 30 minutes. In the control group, no intervention was performed and only the usual methods of pain control were performed for these patients. The severity of patients’ headaches in four time periods (before the intervention and 15, 30, and 60 minutes after the intervention) was measured using the visual scale of pain and vital signs before and after the intervention. Results: The results showed that in all three groups, there was a statistically significant difference between the different stages of pain measurements and the headache score had reduced (df: 4, p < 0.05) (X2: 5.98). There was no difference between the mean scores of the pain levels in the two fragrance groups after the intervention. But there was a significant difference between the fragrance and control groups (df: 6, p < 0.001) (X2: 49.04). Conclusions: Aromatherapy with lavender and valerian essential oils is effective in reducing headaches in patients receiving nitroglycerin infusion and reducing their use of painkillers and narcotics.
