Aromatherapy for Management of Pain, Anxiety, and Nausea in the Acute Care Setting

Overview

The purpose of this interventional study is to investigate the effects of aromatherapy on an acute care unit and whether it is effective in decreasing physical or emotional stressors that occur as a hospitalized patient. This study aimed to expand the limited literature on aromatherapy use in hospitalized adults and its effectiveness in decreasing pain, anxiety, and nausea. The hypothesis was that use of aromatherapy would decrease pain, anxiety and nausea in hospitalized adults and increase patient satisfaction. While there is anecdotal evidence of its efficacy, few studies exist evaluating its effectiveness within peer-reviewed journals, specifically on acute care medical surgical units.

The goal for the study was to collect a sample of one hundred adult patients admitted to an acute care medical surgical unit. A quasi-experimental study with a single-arm pre-/post-test design evaluated one-time use of inhaled aromatherapy on hospitalized adults on an acute care unit. Pre-test tools included a numeric pain rating scale, facial anxiety scale and Halpin's 0-5 nausea scale. Aromatherapy (Elequil aromatabs) was administered for 8 hours. Sleep, satisfaction, well-being, and concurrent medication use were assessed post-aromatherapy. Descriptive and inferential statistics were performed. These subjects had to be conscious, oriented, able to consent, and able to understand the purpose of the study. Exclusion criteria were otolaryngology free flap patients (as this was a study being conducted on an otolaryngology acute care unit and another study was occurring with this population), patients with known allergies to essential oils, those taking sleep medications, or who have an aroma/essential oil contraindication. The use of a pre and post survey was used to measure the effectiveness of aromatherapy on pain, anxiety, and nausea. A baseline assessment was made of these ailments via Qualtrix. Subjects chose the aromatherapy tab fragrance that best fit their chief complaint, which was placed on their gown. After eight hours, a post-application survey to assess pain, anxiety, nausea, sleep/relaxation, overall satisfaction, and overall wellbeing was administered via Qualtrix. A numeric pain scale from 0-10, a 0-5 Likert Anxiety scale and a 0-5 nausea scale were used to measure efficacy. Sleep, satisfaction, and wellbeing was assessed with yes/no. A chart review to determine any measurable benefits in the reduction of related medications while using aromatherapy was to be conducted once one hundred subjects were obtained. The period for this study was approximately fifteen months.
