With 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.
A single blind randomized control trial design was used.
On 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.
Among 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.
CB 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.
