Effect of Intraoperative Instrumental Music and Operating Room Noise Reduction on Anesthetic and Analgesic Requirements in Pediatric Patients Aged 3-18 Years Undergoing Surgery Under General Anesthesia: A Randomized Controlled Trial (MUSIC-OR)
EFFECT OF INTRAOPERATİVE INSTRUMENTAL MUSİC AND OPERATİNG ROOM NOİSE REDUCTİON ON ANESTHETİC AND ANALGESİC REQUİREMENTS İN PEDİATRİC PATİENTS AGED 3-18 YEARS UNDERGOİNG SURGERY UNDER GENERAL ANESTHESİA: A RANDOMİZED CONTROLLED TRİAL
This randomized controlled clinical trial aims to evaluate the effects of intraoperative instrumental music and operating room noise reduction on anesthetic and analgesic requirements in pediatric patients aged 3-18 years undergoing elective surgery under general anesthesia.
A total of 180 patients will be randomly assigned to one of three groups: an instrumental music group, a noise reduction group, or a routine care control group. In the music group, patients will be exposed to instrumental music through headphones during surgery. In the noise reduction group, operating room noise levels will be minimized using a standardized acoustic management protocol. The control group will receive standard anesthetic care without any acoustic intervention.
All patients will undergo standardized general anesthesia. The primary outcomes will be intraoperative volatile anesthetic consumption (sevoflurane use and MAC values) and opioid requirements. Secondary outcomes will include hemodynamic parameters, postoperative pain scores, emergence delirium, and post-anesthesia care unit (PACU) length of stay.
The study does not involve any experimental drugs, invasive procedures, or additional risks beyond routine clinical care. The findings may help determine whether simple non-pharmacological acoustic interventions can reduce anesthetic and analgesic requirements and improve perioperative outcomes in pediatric patients.

Descripción detallada
This study is a prospective, single-center, three-arm randomized controlled trial including pediatric patients aged 3-18 years who are scheduled for elective surgery under general anesthesia.
Participants will be randomly assigned to one of three groups: intraoperative instrumental music, operating room noise reduction, or routine care. In the music group, instrumental music will be delivered through headphones during surgery. In the noise reduction group, operating room noise will be minimized using a standardized acoustic management approach. The routine care group will receive standard anesthesia care without an additional acoustic intervention.
General anesthesia will be managed according to a standardized protocol. Anesthetic depth, hemodynamic variables, anesthetic consumption, opioid use, postoperative pain, emergence delirium, and recovery room stay will be recorded and compared between groups.
The study is designed to investigate whether simple non-pharmacological acoustic interventions during surgery can reduce anesthetic and analgesic requirements and improve early postoperative recovery in children.

Cohortes e Intervenciones
Grupo / Cohorte |
|---|
|
Instrumental Music Group
Participants randomized to this group will receive instrumental music through headphones during surgery under general anesthesia.
Music playback will begin after induction of anesthesia and continue throughout the surgical procedure.
Standard anesthesia management will be maintained for all participants.
|
|
Noise Reduction Group
Participants randomized to this group will undergo surgery under general anesthesia in an operating room where environmental noise is minimized using a standardized noise reduction protocol.
Standard anesthesia management will be maintained for all participants.
|
|
Routine Care Control Group
Participants randomized to this group will receive standard perioperative care and general anesthesia without any additional acoustic intervention, music exposure, or noise reduction measures.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Intraoperative Sevoflurane Consumption
Periodo de tiempo: From induction of anesthesia until completion of surgery (up to 4 hours)
|
Total intraoperative sevoflurane consumption will be measured using average MAC values and total volatile anesthetic consumption recorded by the anesthesia machine during the surgical procedure.
|
From induction of anesthesia until completion of surgery (up to 4 hours)
|
|
Intraoperative Anesthetic and Opioid Consumption
Periodo de tiempo: From induction of anesthesia until completion of surgery (up to 4 hours)
|
Total intraoperative sevoflurane consumption and opioid requirement will be recorded throughout the surgical procedure.
Sevoflurane consumption will be assessed using average MAC values and total volatile anesthetic use recorded by the anesthesia machine.
Opioid requirement will be assessed as the total intraoperative opioid dose administered per kilogram of body weight.
Outcomes will be compared among the instrumental music, noise reduction, and routine care groups.
