Effect of Aromatherapy on Pain, Anxiety and Sleep Quality in Burn Patients

After 5 patients were included in the sample size of the study, intervention and control groups, power analysis was performed using the G\*Power Software (3.1.9.2) program. With a margin of error of 5%, an effect size of 0.15, and a power of 95%, the sample group size was calculated as 54 patients. Considering that data loss might be 10% on average in the study, it was decided to recruit 60 patients. Participants were randomized according to patient rooms. There are a total of 11 rooms and 16 beds in the burn unit, 5 double and 6 single. 11 rooms are numbered sequentially according to their location in the corridor. In the intervention group, seven drops of lavender essential oil were dripped onto a 5x5 gauze pad in the morning and evening, for 20 minutes, 10 cm away from the nose, and sniffed. In the placebo control group, seven drops of saline/sterile water were dripped onto a 5x5 gauze pad in the morning and evening, and they were put to sniff for 20 minutes, 10 cm away from the nose. Green food coloring was added (one drop of food coloring to 5 ml of sterile/saline water) to make sterile/saline water similar to lavender oil. Data were collected using Individual Data Collection Form, Spielberg State Anxiety Scale, Visual Analog Scale, Richard Campbell Sleep Scale before and after five days of morning and evening aromatherapy application.
