Effect of patient selected music therapy on propofol consumption in laparoscopic cholecystectomy under total intravenous anaesthesia: A randomised controlled trial

##article.abstract##

Traditionally, a combination of drugs and blocks have been used to provide balanced anaesthesia and make the perioperative experience satisfying for the patient. However, different groups of anaesthetic agents have certain limitations. Music therapy has shown promising results in reducing perioperative stress thereby decreasing the requirement of anaesthetic agents. This research aims to study the effect of intraoperative music therapy on propofol consumption. This was a randomized controlled trial conducted in patients undergoing laparoscopic cholecystectomy under TIVA. Patients were randomly allocated in two groups (Music - M and Control - C) and patient selected music played using noise cancelling headphones in group M. The primary outcome was to compare consumption of propofol (mg/kg/hr) required. The secondary objectives were to compare intra-operative hemodynamic parameters, additional intraoperative fentanyl required, quality of awakening, patient satisfaction, and change in serum cortisol levels in the two groups. Total propofol consumption was significantly reduced in group M. Group M also showed a significantly reduced fentanyl requirement, improved hemodynamic stability, a reduction in post operative serum cortisol levels and an improved quality of awakening. Intraoperative music therapy can be used as a simple, non-pharmacological method to reduce anaesthetic requirement and aid in reducing perioperative stress.
