Methods: This study is a randomized and controlled clinical trial involving 82 patients undergoing orthopedic surgery of wrist fracture in randomly selected hospitals of Tehran in 2015. The patients of the treatment group, 8 and 16 hours after surgery, sniffed 3 drops of essential oil of lemon for 20 minutes and the intensity of pain was measured half an hour after the intervention. For the control group, routine healthcare services continued. Data was analyzed using the SPSS 21 software and descriptive and inferential statistics. Moreover, in order to measure the effects of aromatherapy and change trends, repeated measures ANOVA was used. Chi-square test was also used to determine the success rate of the treatment.

Results: Comparison of changes in pain scores between the two groups showed that there is a significant relationship (p=.049) between the intensity of pain in control and treatment groups during the examined intervals (mean of pain and anxiety reduction 8 and 16 hours after surgery). There was also a significant relationship between the recovery rates of the control and treatment groups and different intervals (p=.008).

Conclusion: The results of the study indicate a positive impact of aromatherapy with essential oils of lemon on the reduction of pain, 8 and 16 hours after orthopedic surgery.
