BACKGROUND:Postoperative nausea (PON) is a common complication of anesthesia and surgery. Antiemetic medication for higher-risk patients may reduce but does not reliably prevent PON. We examined aromatherapy as a treatment for patients experiencing PON after ambulatory surgery. Our primary hypothesis was that in comparison with inhaling a placebo, PON will be reduced significantly by aromatherapy with (1) essential oil of ginger, (2) a blend of essential oils of ginger, spearmint, peppermint…

Aromatherapy for the treatment of PONV in children: a pilot RCT

Aromatherapy had a small non-significant effect size in treating postoperative nausea and vomiting compared with control, and a large-scale randomized control trial would not be feasible at this institution and would be of doubtful utility.

Aromatherapy Blend for Postoperative Nausea in Ambulatory Surgery Patients.

Aromatherapy for Postoperative Nausea in Acute Care-Evidence and Future Opportunities.

Limited evidence suggests that inhaled vapor of peppermint or ginger EO may reduce the frequency and severity of nausea and vomiting and decrease antiemetic medication requirements, and aromatherapy appears to be linked to increased patient satisfaction.

Aromatherapy for treatment of postoperative nausea and vomiting.

Isopropyl alcohol was more effective than saline placebo for reducing postoperative nausea and vomiting but less effective than standard anti-emetic drugs and there is currently no reliable evidence for the use of peppermint oil.

Aromatherapy for postoperative nausea and vomiting

From the evidence of the systematic review, the use of isopropyl alcohol vapour inhalation as an adjunct therapy for postoperative nausea and vomiting is unlikely to be harmful and may reduce nausea for some adult patients.

While well received, well tolerated, nontoxic, and noninvasive, ginger aromatherapy did not significantly decrease nausea in patients enrolled in this study.

Isopropyl Alcohol Inhalation: Alternative Treatment of Postoperative Nausea and Vomiting

IPA was found to be effective for treatment of postoperative nausea and vomiting for patients who have general anesthesia for a surgical procedure and treatment with IPA was significantly more cost effective than standard drug treatment.

A comparative analysis of isopropyl alcohol and ondansetron in the treatment of postoperative nausea and vomiting from the hospital setting to the home.

It is determined that using IPA after discharge from the postanesthesia care unit is a valuable method to control PONV in the hospital and at home and suggests that IPA is much faster than ondansetron for 50% relief of nausea.

A Double-Blind Randomized Controlled Trial of Ginger for the Prevention of Postoperative Nausea and Vomiting

Ginger BP in doses of 0.5 or 1.0 gram is ineffective in reducing the incidence of postoperative nausea and vomiting, and the results were essentially unchanged when adjustment was made for concomitant risk factors.

The efficacy of ginger in prevention of postoperative nausea and vomiting after major gynecologic surgery.

Ginger has efficacy in prevention of nausea and vomiting after major gynecologic surgery and the incidence and frequency of vomiting in group A were lower than group B and side effects caused by ginger were not detected.

The control, placebo and experimental groups of gynaecological patients were compared, using variables known to affect postoperative nausea, and peppermint oil was found to be homogeneous for the purposes of the study.

Efficacy of ginger for nausea and vomiting: a systematic review of randomized clinical trials.

A systematic review of the evidence from randomized controlled trials for or against the efficacy of ginger for nausea and vomiting found one study was found for each of the following conditions: seasickness, morning sickness and chemotherapy-induced nausea.

Prevention and Treatment of Postoperative Nausea and Vomiting

This multimodal PONV management approach includes use of multiple different antiemetics medications (double or triple combination antiemetic therapy acting at different neuroreceptor sites); less emetogenic anaesthesia techniques; adequate intravenous hydration; and adequate pain control.
