PurposeWith little scientific evidence to support use of aromatherapy for postoperative nausea and/or vomiting (PONV) symptoms, this study evaluated controlled breathing with peppermint aromatherapy (AR) and controlled breathing alone (CB) for PONV relief.DesignA single blind randomized control trial design was used.MethodsOn initial PONV complaint, symptomatic subjects received either CB (n = 16) or AR (n = 26) intervention based on randomization at enrollment. A second treatment was repeated at 5 minutes if indicated. Final assessment occurred 10 minutes post initial treatment. Rescue medication was offered for persistent symptoms.FindingsAmong eligible subjects, PONV incidence was 21.4% (42/196). Gender was the only risk factor contributing to PONV symptoms (P = .0024). Though not statistically significant, CB was more efficacious than AR, 62.5% versus 57.7%, respectively.ConclusionsCB can be initiated without delay as an alternative to prescribed antiemetics. Data also support use of peppermint AR in conjunction with CB for PONV relief.Copyright © 2014 American Society of PeriAnesthesia Nurses. Published by Elsevier Inc. All rights reserved.
