Lavender (Lavandula Angustifolia) Aromatherapy Inhalation as an Anti-Anxiety Treatment for Pain

This clinical trial will assess whether aromatherapy inhalation (especially lavender extract essential oil) can be used as a complementary therapy for anxiety and pain. In this study, outcomes will be measured using the Numeric Rating Scale (NRS) for pain score and State-Trait Anxiety Inventory (STAI) questionnaire to assess state and trait anxiety scores. The two questionnaires above will be used to determine pre-post pain and anxiety scores after exposure. This study's primary research question is "Does linalool in lavender extract essential oil aromatherapy reduce anxiety in patients with pain complaints ?". With the question above, it is hypothesized that linalool can be an anti-anxiety towards pain. The product of aromatherapy will be tested in a GC-MS assay for every substance inside and proving linalool as a key substance. To prove the effect of linalool, this study will compare diffused lavender extract essential oil aromatherapy with a placebo to determine its effect as an anxiety reliever.

About this study

The objective in this clinical trial is to evaluate the effect of linalool in lavender extract essential oil aromatherapy as anti-anxiety treatment for pain. The linalool inside lavender extract will be proven with GC-MS assay first. Then, after linalool has been confirmed as a key substance inside the extract, the lavender extract essential oil will be mixed with water to dilute it before it is exposed to participants in the experimental group. This study will assess anxiety and pain scale using the Numeric Rating Scale (NRS) for pain score and the State-Trait Anxiety Inventory (STAI) before exposure and 15 minutes after the exposure has been done. This complementary therapy can be an innovation in addition to conventional pain therapy, with the theory that anxiety towards pain can amplify the pain, and GABA-ergic activity in the brain can help inhibit the pain.

Study design: This study is using a Randomized Controlled Trials (RCT) with pre and post test assessment. This study will be blinding the participants and care provider.

Allocation:

  • Participant will be allocated using simple randomization to the experimental or placebo group
  • All the participants who agreed to the informed consent will be included and randomized to the experimental or placebo group
  • Then every participant will be exposed to the intervention as scheduled personally

Group/Arm:

  • Placebo / Control group will be exposed to diffused water (H2O) for 30 minutes

Data Analysis Plan: The data will be analyzed using univariate analysis and bivariate analysis (Independent T-Test, Paired T-Test, Wilcoxon Test, ANOVA, and/or Mann-Whitney test)

Anticipated outcome:

  • Reduction in anxiety score
  • Reduction in pain score
  • Low risk of allergies
  • No adverse event

Risks:

  • Allergies
  • Adverse event

Benefits:

  • Innovation in addition to pain conventional therapy as a complementary therapy

Treatment and study plan

Lavender Extract Aromatherapy

Combination Product

This group will be exposed to diffused Lavender Extract Essential Oil Aromatherapy. Aromatherapy given to this group will be linalool concentrate (verificated with GC-MS of the essential oil) in forms of 2 mL Lavender Essential Oil from Young Living diluted in 40 mL water for 30 minutes

Placebo

Other

This intervention will be just an exposure of diffused water (H2O) for 30 minutes as a control to experimental group

Primary outcomes

  1. Anxiety Score

    Time frame: Before exposure and 15 minutes after exposure has done

    This parameter measured using State Trait Anxiety Inventory (STAI) Questionnaire. This questionnaire can be used to assess state and trait anxiety. It is consist of 2 segment, state segment for current anxiety scale and trait segment for any consistent anxiety feeling scale. This questionnaire have score range between 20 (minimum) and 80 (maximum). It is classified as mild anxiety for 20-39 points, moderate anxiety for 40-59 points, and severe anxiety for 60-80 points. This questionnaire has been tested for its validity by McDowell in 2006 with interval value 0,88. For its reliability, it has been tested by McDowell too in 2006 with alpha for S part 0,93 and T part 0,91

Secondary outcomes

  1. Pain Scale

    Time frame: Before exposure and 15 minutes after exposure has done

    This parameter measured with NRS questionnaire for assessing pre-post exposure pain scale changes. This questionnaire will have score range between 0-10 points. 0 point stands for no pain, 1-3 points will stands for mild pain, 4-6 for moderate pain, and 7-10 stands for severe pain
