The Physical and Psychologic Effects of Aromatherapy in Cancer Patients During Chemotherapy

Background: Stress is the critical method for survive of reacting to a condition including a threat, challenge or physical and psychological challenge. Stress either physiological or biological is an organism's response to a stressor such as an environmental condition. Stimuli that alter an organism's environment are responded to by multiple systems in the body. The hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system are major systems which the body reacts to the stress. It has been reported that cancer patients receiving chemotherapy perceived a lot of stress. It has been believed and well known that stress-related illness is one of the reasons contributing to the increase in long-term sick leave during the last decade in many countries.

Purpose: The aims of this study are to evaluate the effects of aromatherapy on cancer patient receiving chemotherapy: 1) for physical effects by meridian electrical conductance, heart rate variability (HRV), vital sign, visual analogue scale (VAS) for pain; 2) for psychologic effects by State-Trait Anxiety Inventory (STAI).

Materials and methods: This is a prospective, pre post comparison study. A total of 40 cancer patients receiving chemotherapy will be recruited as participants in this study. The characteristics data will be collected in all participants. Blood orange and rosewood will be chosen as the essential oils for aromatherapy in this study. Essential oils will be applied to all participants by inhalation for 30 minutes. Meridian electrical conductance, HRV, vital sign, VAS for pain, and STAI were evaluated and compared before and after aromatherapy.

Expected outcomes: It is expected to understand more about the effects of aromatherapy on the meridian system, HRV and emotional status by undertaking 30 minutes session aromatherapy intervention for cancer patients receiving chemotherapy. The results may suggest aromatherapy as one of the affiliated programs of chemotherapy.
