The study intervention consists of 3 essential oils: lavender, mandarin and peppermint administered on an inhalation patch affixed in the chest region of the participant gown. The inhalation patch consists of hydrogel cast onto polyester film, supported by non-woven polyester fabric, covered with a polyethylene film. The proprietary foil-backed lamination on the patch is used to provide an occlusive barrier that prevents any essential oil from being absorbed through the skin. The placebo will consist of a comparable sized felt patch with adhesive backing with no essential oil applied.
Use of inhaled essential oils to reduce the symptoms of pain or nausea, enabling a patient to have increase participation with PT or OT, thereby minimizing hospitalization-related risks and potentially reducing the length of stay in the hospital.
