|Official Title:||A Randomized Prospective Placebo-Controlled Study of the Effects of Lavender Aromatherapy on Preoperative Anxiety in Breast Surgery Patients|
- Anxiety reduction [ Time Frame: 20 minutes before surgery ] [ Designated as safety issue: No ]By monitoring vital signs, we hope to show that lavender aroma therapy reduces preoperative anxiety in patients undergoing breast surgery. Tests are done before surgery. Tests are done, aromatherapy is given for 10 minutes, then tests are repeated.

|Estimated Primary Completion Date:||September 2013 (Final data collection date for primary outcome measure)|
Active Comparator: Lavender oil
Lavender oil aromatherapy

2 drops unscented mineral oil for aromatherapy
Many patients undergoing surgery experience anxiety in the preoperative setting. Pharmacologic anxiolytics require monitoring and cause excess sedation which often interferes with the ability to assess and obtain consent from a patient in the preoperative holding area. Lavender aromatherapy is an alternative treatment for anxiety which is safe, inexpensive, easy to administer, and not overly sedating. In addition to its benefits in the preoperative setting, anxiolysis and reduction in sympathetic drive can lead to reduction in the intraoperative anesthetic and postoperative analgesic requirements. This in turn can lead to faster recovery and expedited discharge from the post anesthesia care unit.
In the proposed study, we would evaluate the efficacy of aromatherapy with lavender oil in reducing anxiety prior to breast surgery. The study group would receive lavender oil preoperatively and the placebo group would receive unscented oil preoperatively. Before and after treatment, anxiety level would be measured using the Spielberger State-Trait Anxiety Inventory. Additionally, vital signs and Bispectral index (BIS) will be measured before and after treatment, as further indicators of anxiety level. We hypothesize that lavender aromatherapy will decrease anxiety and subsequently will reduce blood pressure, heart rate, and BIS.
