Effect of Binaural Beat Music on Perioperative Anxiety and Stress among patients undergoing Femur bone Fracture Surgery under Spinal Anesthesia: A prospective randomized study

Patients subjected to surgeries are exposed to intense anxiety and stress. Spinal anaesthesia further increases anxiety because patient is either awake or slightly sedated and exposed to multiple anxiety provoking visual and auditory stimuli. Perioperative anxiety and psychological stress lead to activation of HPA  and sympathetic nervous system resulting in neurohormonal responses reflected in cortisol levels and causes hemodynamic instability. It calls for increased pharmacological interventions which might hinder recovery following anaesthesia and induce undesirable dose dependent cardiorespiratory and CNS depression.

Extensive researches on efficacy of binaural beat music in anxiety, pain perception and relaxation has shed light to use it as an intervention to alleviate anxiety and physiological responses to surgery. Various studies have indicated the prevalence of anxiety highest with orthopedics procedures which uses hammers, drills and other louder instruments .Anxiety comparatively higher among patients who had femur bone procedures because of sudden constraints on movement couples with excruciating pain and quick medical process that decided the diagnosis and treatment course.

Thus we decided to conduct a randomized control study on effects of binaural beat music on perioperative anxiety and stress in patients undergoing femur bone fracture surgery under spinal anesthesia. As salivary biomarkers have proven to be better than blood markers in stress related research ,the influence of binaural music on stress analyzed by salivary cortisol  and perioperative anxiety in both groups compared using more objective scale such as State Trait Anxiety Inventory scoring scales.
