BackgroundAromatherapy has been used to reduce anxiety in a variety of settings, but usefulness associated with breast biopsies has not been documented.
AimsThis study was conducted in women undergoing image-guided breast biopsy. We explored the use of two different aromatherapy scents, compared to placebo, aimed at reducing anxiety with the intent of generating new knowledge.
MethodsThis was a randomized, placebo-controlled study of two different types of external aromatherapy tabs (lavender-sandalwood and orange-peppermint) compared with a matched placebo-control delivery system. Anxiety was self-reported before and after undergoing a breast biopsy using the Spielberger State Anxiety Inventory Scale.
Results and FindingsEighty-seven women participated in this study. There was a statistically significant reduction in self-reported anxiety with the use of the lavender-sandalwood aromatherapy tab compared with the placebo group (p = .032). Aromatherapy tabs reduced anxiety during image-guided breast biopsy.
Linking Evidence to ActionThe completion of the biopsy provided some relief from anxiety in all groups. The use of aromatherapy tabs offers an evidence-based nursing intervention to improve adaptation and reduce anxiety for women undergoing breast biopsy. Lavender-sandalwood aromatherapy reduced anxiety and promoted adaptation more than orange-peppermint aromatherapy or placebo.
