Comparison of Binaural Tone Music vs Patient Choice Music vs Midazolam on Perioperative Anxiety in Patients Posted for Surgery Under Spinal Anaesthesia: a Randomized Control Trial

Background Perioperative anxiety affects patients' hemodynamics by increasing stress levels, leading to delayed recovery. In this study, we compared the anxiety-reducing effect of music (patient choice and binaural tone music) with midazolam for perioperative anxiolysis in patients undergoing surgery under spinal anaesthesia.Methods After obtaining institutional ethical clearance and informed written consent, a total of 225 patients classified as ASA grades 1 and 2 (American Society of Anesthesiologists) were enrolled and randomised into three groups of 75 patients per group. Group A patients received research-selected music (binaural tone) via noise-cancelling headphones, Group B received intravenous midazolam (minimum of 1 mg to 2 mg maximum) as per clinical judgement, and Group C participants provided patient-preferred music via noise -cancelling headphones. The patient's perioperative anxiety was assessed using a visual analogue anxiety scale at regular time intervals.Results Anxiety scores were significantly reduced in the patient's choice music group (Group C) and binaural tone music group (Group A) as compared to the midazolam group (Group B). Postoperative pain scores were statistically significantly lower in Group C, followed by Group A and Group B. On comparing patient satisfaction scores, using numerical rating scores, 96% of patients in Group C achieved excellent scores with a p-value of 0.007.Conclusion Binaural tone music and patient choice music can be suitable alternatives to pharmacological therapies for perioperative anxiolysis.
