A Randomized Prospective Placebo-Controlled Study of the Effects of Lavender Aromatherapy on Preoperative Anxiety in Breast Surgery Patients
The study is designed to see if lavender aroma therapy reduces pre-operative anxiety in
breast surgery patients.
breast surgery patients.
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.
