Impact of inhalation aromatherapy with Damask Rose () on stress, anxiety and hemodynamic parameters of patients undergoing coronary angiography: a single blind randomized clinical trial.

OBJECTIVES

Coronary arteries angiography is used commonly for diagnosing cardiovascular diseases. In spite of the low risk of coronary artery angiography method, it could lead to stress, anxiety and consequently hemodynamic changes in patients. This study aimed to assess the effects of inhalation aromatherapy with on stress, anxiety, and hemodynamic parameters of patients undergoing coronary angiography.

METHODS

A single-blind randomized clinical trial was conducted on 98 patients in Besat Educational Hospital, Hamadan, Iran. Before coronary angiography, patients at aromatherapy group inhaled five drops of 40% for 20 min and in the control group, patients inhaled distilled water. Stress, anxiety, and hemodynamic parameters were measured before and after the intervention using DASS-21 questionnaire and checklist.

RESULTS

Data were analysed by SPSS 16 software using descriptive and inferential statistics such as paired t-test and non-parametric tests. There were significant differences in terms of stress and anxiety severity in patients at aromatherapy group (p=0.005) and control group (p=0.001). There were significant differences in terms of hemodynamic parameters such as heart rate (p=0.001), mean arterial pressure (p=0.001), systolic (p=0.003) and diastolic blood pressure (p=0.001) and SpO (p=0.02).

CONCLUSIONS

Inhalation aromatherapy with can significantly decrease stress and anxiety severity and improve hemodynamic parameters of patients undergoing coronary angiography.
