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).
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.
