Clinical Trial Summary

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.

Description:

Preoperative anxiety is a common occurrence that has the potential to be harmful, with prevalence rates in the literature ranging from 27% to 80%. Clinical manifestation ranges from malaise to acute stress disorder that meets the criteria of Diagnostic and Statistical Manual of Mental Disorders 5 (DSM5).It is associated with a rise of peri-operative morbidity and mortality. Anti-anxiety medications may be effective but it comes with a number of undesirable adverse effects. Aromatherapy is a non-pharmacological approach that is alluring, affordable, and inexpensive and has minimal side effects, but there aren't enough studies to support its efficacy. The aim of our 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 The patients were seen the night before the surgery, a pre-anesthetic visit was performed. 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. Surgery day, one hour before operation, vital signs were taken: Heart rate, respiratory rate, pulse oximetry, systolic arterial pressure and diastolic arterial pressure. Then patients were assessed for anxiety using, Visual Analogue scale-anxiety and APAIS scale. Next, the investigators proceeded with the intervention and patients were assigned into the 3 group of the study. In the operating room, Spinal anesthesia was performed. After surgery the investigators evaluated anxiety level (VAS-A) and post-operative pain.

Drug:
• lavender essential oil inhaled using cotton balls
cotton balls impregnated with 3 drops of lavender essential oil inhaled from a distance of 10 cm during 20 minutes and pure oxygen administered through a face mask.
• lavender essential oil inhaled using face mask
These three drops were already diluted by five milliliters of distilled water and were sprayed in the area by a nebulizer throughout a face mask. A cotton ball soaked with water was put 10 cm next to the patient.
