Effect of Aromatherapy on Preoperative Anxiety Level

The aim of the study was to evaluate the efficacy of lavender aromatherapy in reducing pre-operative anxiety in patients undergoing surgical procedures under spinal anesthesia. This was a prospective double blinded randomized controlled trial. After patient's approval, the anxiety level was assessed preoperativetively with Visual Analogue scale-anxiety and APAIS scale. To rule out any lavender sensitivity, all subjects were given a skin patch test. This was accomplished by applying a drop of lavender oil to the back of the hand and covering it with a Tegaderm dressing to prevent inhalation and spread of the oil. After randomisation and allocation, the investigators prooceeded with the intervention preoperatively. In the operating room, the acte under spinal anethesia was performed. Then we collect data postoperatively.
