A Study of the Effects of Lavender Aromatherapy on Preoperative Anxiety in Breast Surgery Patients

A Randomized Prospective Placebo-Controlled Study of the Effects of Lavender Aromatherapy on Preoperative Anxiety in Breast Surgery Patients

The purpose of this study is to determine the effects of lavender aromatherapy on preoperative anxiety by measuring changes in pulse rate and anxiety core using Spielberger State-Trait Anxiety Index questionnaires and on postoperative pain medicine usage. Study participants will then be randomized into one of four groups; either they will receive 2 drops of lavender (Lavandula Angustifolia) oil (LO) or 2 drops of Michelia Alba Leaf oil (MA) or 2 drops of unscented Almond oil (AO) or two drops water on the inside of an oxygen face mask for 15 minutes. Linalool makes up ~30% of Lavandula Angustifolia oil and is believed to be its most active anti-anxiety component. Before and after treatment, anxiety level will be measured using the Spielberger State-Trait Anxiety Inventory.
