The Effects of Inhaled Aromatherapy on Chemotherapy Induced Nausea (CINV) and Vomiting

Study Summary

This study is a three group, randomized, double blind, placebo-controlled trial with two repeated measurements. The same measurements will be collected for each participant during two consecutive chemotherapy treatment cycles.Subjects will be provided with written instructions as an educational handout as well as essential oil safety information. Subjects will be able to demonstrate an ability and accurate understanding of the proper use of the diffusers, using a demonstration diffuser, at the time of consent. At the time the subject will provide written informed consent, they will be randomly assigned to one of the three groups with a pocket diffuser containing either ginger essential oil, peppermint essential oil, or vanilla extract )placebo- control). This is based on a pre-determined list of random assignments. Each subject will be instructed to inhale from the pocket diffuser beginning on the day of their chemotherapy (Day 1) and continue using the inhaler for the next three consecutive days (Day 1-Day 4). The subjects will remove the cover of the pocket diffuser, place the pocket diffuser approximately an inch away from their nose and inhale three times with deep breathing (i.e., three sniffs). Subjects will take 3 sniffs of the aromatherapy inhaler three times daily (morning, afternoon, and evening). In addition to the Pre-treatment Assessment, occurring before each of the 2 cycles of chemotherapy, the subjects will be contacted to complete assessments at approximately 24 and 72 hours post-chemotherapy. A member of the study team will call the participant again at their preferred time of day to ask the survey questions. The same procedures will be repeated during the participant's second cycle of chemotherapy, which is likely two or three weeks after the first one.

Primary Outcome

N\&V experienced during the first 24 hours after chemotherapy administration as measured by the Memorial Symptom Assessment Scale's nausea and vomiting dimension with values for symptoms, if experienced, on a 4-point scale; its frequency, if appropriate, on a 4-point scale; and its associated distress on a 5-point categorical scale. The higher the score determines a worse outcome in all areas.

Interventions

• OTHER Peppermint Essential Oil, Ginger Essential Oil, or Pure Vanilla Extract
