The Effect of Pre-recorded Lullaby in a Childs Own Mothers Voice on Radiotherapy Procedure under Sedation : An Observational Study

Though process of delivering radiotherapy is painless, sedation is often required for pediatric patients undergoing radiotherapy to ensure their comfort, anxiety reduction, and immobilization during the procedure.However, the repeated use of general anesthetics, such as benzodiazepines and ketamine, in pediatric patients has raised concerns about potential long-term neurocognitive effects on the developing brain.While anesthesia-sparing distraction methods have been attempted, they are challenging to implement successfully in children under three years of age.Music therapy has been traditionally used to calm anxious patients.Recently, in our centre we have started playing pre-recorded lullaby in patient’s own mothers voice as an adjuvant method along with routine sedatives to achieve anxiolysis and immobilisation during radiotherapy. While some of the anaesthesiologists are adopting this new methodology, rest of them are still following the conventional method (delivery of sedatives only, without playing the lullaby). In this prospective observational cohort study, we aim to observe the effect of playing a prerecorded lullaby in the patient’s own mother’s voice as an adjuvant method alongside routine sedation to achieve anxiolysis and immobilization during radiotherapy and compare them with the conventional general anesthesia technique.
