In the experimental group; firstly patient identification form, patient registration form and STAI were applied to patients, after that lavender oil inhaled at least 5 minutes (mean: 5-10 min). Following this process STAI and patient registration form were applied again. While n te control group; patient identification form, patient registration form and STAI were applied to patients and after at least 20 min (mean: 20-25 min) STAI and patient registration form were applied again. Results: Under scope of research; the mean level of anxiety before aromatherapy in test group was 65.07±6.24 decreased to 26.60±7.47 after aromatherapy. However, in the control group it was 66.29±4.20 before the aromatherapy and reached to 63.50±2.94 after aromatherapy. There was a significant reduction in test group compare with in control group. Changes of vital signs rates were examined in test group before and after aromatherapy, revealed the mean of SBP rate decreased from 127.54±20.27 to 124.36±16.27, the mean of respiratory rate decreased from 21.85±2.51 to 20.54±3.09, the mean of SPO2 rate increased from 93.63±1.89 to 94.09±1.54 and determined mean differences of this there variables was statistically significance. Although after aromatherapy decreases were observed rates of DBP and pulse in test group, there was no significance change statistically.
