Conditions
Summary
This prospective randomized study aims to evaluate the effects of three auditory conditions-lullaby music, white noise, and silent headphone use-on sedation depth, anesthetic drug requirements, and recovery outcomes in children undergoing MRI. A total of 150 pediatric patients aged 6 months to 12 years will be assigned to one of three groups: lullaby, white noise, or silent headphone (isolation) control. All participants will receive routine sedoanalgesia according to institutional protocol. Vital signs, sedation depth, movement requiring sequence repetition, additional anesthetic dosing, and intra-procedural complications will be recorded. Post-procedure recovery will be assessed using the Ramsey Sedation Scale and the Modified Aldrete Score until discharge criteria are met. The study will compare whether auditory stimulation influences sedation stability, reduces anesthetic consumption, and improves recovery time during pediatric MRI.
Eligibility
Inclusion Criteria5

Exclusion Criteria9
- Age under 6 months or over 12 years.
- Known allergy, intolerance, or contraindication to sedative medications used in institutional protocols.
- History of airway anomalies, difficult airway, or conditions increasing anesthesia risk.
