Effects of Aromatherapy on Nausea Levels

Effects of Aromatherapy in Decreasing Nausea Levels in the Post-operative Bariatric Patient Population on a Surgical Unit

Aromatherapy is the therapeutic use of essential oils from plants for the improvement of physical, emotional, and spiritual well-being. Healthcare providers play an important role in improving the care of patients with nausea. Aromatherapy is a complementary therapy that may help with post-operative nausea in the adult post-operative bariatric patient population. The purpose of this study is to evaluate the effects of aromatherapy intervention on nausea levels with post-operative bariatric patients once they are on the surgical unit.

Subjects will be provided with information about this research study by the following means: a member of the research team- Inova Medical Group (IMG) Nurse Practitioners will discuss the research study during the patient's second pre-operative visit; study information will be uploaded to their MyChart portal; and flyers will be available in the IMG office (refer to appendix A: IMG office flyer). Interested patients will be able to fill out a brief form (refer to appendix B: Interested patient card) requesting to be contacted for further information, this form will be placed in a secure box at the reception desk or the patients can indicate interest by contacting one of the research team members. A member of the research team may need to access medical record information in order to confirm potential patient's phone number and or email address for further contact. A member of the research team will contact any interested patients and answer any questions regarding the research study. Consent will be obtained while the patient is in the peri-operative holding area on day of surgery by a member of the research team, excluding the IMG Nurse Practitioners. The research team member will determine if the patient is eligible for the study, discuss the study, answer any questions, and obtain consent (refer to appendix C: Consent). All members of the research team have completed Informed Consent Training. Once the consented post-operative bariatric patient complains of initial nausea on the Surgical Unit, the direct care nurse or research team member will ask the patient to rate their nausea level using a VAS on a 0-3 scale. Patients will be provided with either product A or B based on randomization scheme calculated by SAS (ver.9.4, Cary, NC). The patient will receive a one-time aromatherapy intervention. Nausea levels will be reassessed 5 minutes after the aromatherapy intervention. If the nausea level does not improve after the study drug intervention an antiemetic medication will be offered (refer to appendix D: Data Collection Form A).

If you agree to participate in the study you will be randomized (assigned by chance) to a product group (product A or product B) and will receive either the active intervention or placebo. There is a 50% or 1 in 2 chance of you receiving either product A or product B upon your initial complaint of nausea when on the Surgical Unit. You will receive a one-time dose for your nausea using either product A or product B based on trial randomization.

Post administration nausea levels will be the source of information for this measure To determine the effectiveness of using aromatherapy as a first line intervention in place of an antiemetic in post-operative bariatric patients who experience nausea on the surgical unit at IFOH.

Medication administration record will be the source of information for this measure. effective with a particular post-operative bariatric patient population (sleeve gastrectomy , Roux-En-Y, revisional bariatric surgery) on a surgical unit than with another.

Inclusion Criteria: Patients ≥ 18 years of age admitted to the Surgical Unit who are experiencing an initial episode of nausea status post laparoscopic/ robotic sleeve gastrectomy, and/or laparoscopic/robotic Roux-En-Y (RNY) surgery, and/or revisional bariatric surgery; must be able to read and speak English; able to follow directions; bariatric surgeon is part of Inova Medical Group (IMG) and patient is an inpatient. Exclusion Criteria: Patients < 18 years of age; non-English speaking; not able to follow directions; inability to smell (anosmia); allergy to peppermint, spearmint, ginger and/or lavender; receiving bariatric surgery for gastroparesis; pregnant or breastfeeding; vulnerable subjects; receiving complementary therapy (healing touch and/or music therapy) or presently enrolled in another research study.
