About this study
Official title: Efficacy Of Lavender Aromatherapy on Anxiety and Pain Reduction During Awake Otolaryngologic Procedures
The purpose of this study is to evaluate the efficacy of lavender aromatherapy in adult patients undergoing awake otolaryngologic procedures in the outpatient clinic setting. The main questions it aims to answer are:
- Does lavender aromatherapy help reduce anxiety and/or pain, and improve patient comfort during awake otolaryngologic procedures in the clinic?
- Do patients subjectively find aromatherapy relaxing and/or beneficial during the procedure?
Read more
Researchers will compare lavender aromatherapy to placebo (an odorless liquid) to see if lavender aromatherapy helps improve patient comfort during their awake procedure
Participants will:
- Have their scheduled procedure performed with lavender aromatherapy or placebo during the duration of the procedure
- Take a short, less than 1 minute questionnaire both before and after the procedure, describing their levels of anxiety, pain and subjective impressions of the aromatherapy
- Conditions
- Inferior Turbinate Hypertrophy, Chronic Rhinosinusitis (CRS), Rhinitis, Vasomotor, Thyroid Nodules, Vocal Fold Immobility
- Being tested
- Lavender Aromatherapy, Placebo Aromatherapy
- Keywords
- Aromatherapy, Otolaryngology, Awake procedure
- Medical subject headings
- Rhinitis, Vasomotor, Thyroid Nodule
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lavender AromatherapyOther
Lavender essential oil on cotton ball, and in aromatherapy diffuser
Placebo AromatherapyOther
Saline on cotton ball and in aromatherapy diffuser
| Study group | Role | What they receive |
|---|---|---|
| Lavender Aromatherapy | Experimental | Participants will be exposed to lavender aromatherapy on a cotton ball prior to procedure, and then with a diffuser during the duration of the procedure Receives: Other: Lavender Aromatherapy |
| Placebo | Placebo comparator | Participants will be exposed to placebo odorless liquid, on a cotton ball prior to procedure, and then with a diffuser during the duration of the procedure Receives: Other: Placebo Aromatherapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in visual analog scale anxiety, measured on a 10 cm scale
A 10 cm visual analog scale is widely utilized to measure procedural anxiety, rated from 0 to 10, with 10 being the highest level of anxiety. The patient will provide a vertical mark above their level of anxiety. This number measured in mm (0-100) will be recorded both immediately before the procedure, and after the procedure, where the patient will record their average level of anxiety during the procedure. The change between pre-procedure, and post-procedure, will be recorded for each patient and compared between the lavender aromatherapy and placebo groups. The mean and median pre-procedure and post-procedure values will also be compared between the groups.
Measured: Baseline, Periprocedural and Immediately after the procedure
Likert scale of pain, measured on a scale of 0-10
Patients will be asked to rate their your average level of pain on a scale of 0 (no pain) to 10 (worst possible pain) on a post-procedural questionnaire
Measured: Immediately after the procedure
Likert scale subjective improvement with pain, measured on scale of 1-5
Patients will be asked in post-procedural questionnaire if they felt the aromatherapy helped with pain during the procedure, on a scale of 1 (strongly disagree) to 5 (strongly agree)
Measured: Immediately after the procedure
Secondary outcomes (1)
Subjective Impressions of Lavender Aromatherapy, measured on Likert scale and in Yes/No format in post-procedural questionnaire
Patients will be asked in a post-procedural questionnaire their subjective impressions of the lavender aromatherapy or placebo. The questions will be outlined as below:
Did you feel the aromatherapy was calming during the procedure?
1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree)
Did you find the scent pleasant? 1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree)
Do you use aromatherapy or essential oils regularly? Yes No
Have you ever used aromatherapy or essential oils in the past? Yes No
How likely are you to recommend the aromatherapy for future patients undergoing awake procedures?
1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree)
Measured: Immediately after the procedure
