Abstract
Purpose
To assess the effect of aromatherapy with lavender oil alone, and in combination with music, on pain and anxiety during extracorporeal shockwave lithotripsy for kidney stones.
Methods
This was a single-centre prospective, randomised controlled trial. The subjects were block randomised into 3 study groups, Group 1: Control; Group 2: Aromatherapy only; Group 3: Aromatherapy and music. All subjects were given patient-controlled intravenous alfentanil as standard analgesia. The primary outcome measures were pain and anxiety scores using visual analogue scale (VAS) and State-Trait Anxiety Inventory.
Results
Ninety patients were recruited and randomised prospectively into Group 1 (n = 30), Group 2 (n = 30), and Group 3 (n = 30). For pain outcome, both Group 2 and Group 3 showed a trend towards lower mean VAS pain scores of 2.73 in both groups compared to the control with a mean VAS score of 3.50, but it was not statistically significant (p = 0.272). There was no significant difference in anxiety scores between groups post-treatment.
Conclusions
Our study was unable to show a significant improvement in pain relief and anxiety when aromatherapy with lavender oil was added to standard analgesia alone during shockwave lithotripsy. There was also no difference when aromatherapy was combined with music.
