An Exploration of Certified Registered Nurse Anesthetists’ Knowledge and Use of Aromatherapy for Treatment of Post-Operative Nausea and Vomiting

Abstract

Post-operative nausea and vomiting (PONV) is a common side effect of anesthesia. Despite the current treatment regimen of medications, many patients still suffer from PONV. Therefore, new techniques and treatments for PONV are needed. Aromatherapy offers a potential treatment with a low cost and minimal side effects. To determine the level of knowledge about aromatherapy, and if it is being used in practice, a survey of certified registered nurse anesthetists (CRNAs) was conducted. This study found that only three percent (3%) of the CRNA respondents had received formal education on aromatherapy for PONV. Further, it was determined that although ninety-two percent (92%) of respondents had used inhalation of isopropyl alcohol as a treatment for PONV, only eight percent (8%) of respondents stated that they had used essential oils for relief from PONV. Aromatherapy is an option for treating PONV and CRNAs should have more educational opportunities on aromatherapy for PONV to allow them to feel comfortable providing this safe and minimally invasive treatment option to patients.
