Maternal Voice Versus White Noise in Pediatric Surgery
22. august 2026 opdateret af: Sinem Öztürkler, Kocaeli University
Maternal Voice Versus White Noise: Effects on Pain, Comfort, and Physiological Responses in Pediatric Surgery
This randomized controlled study will evaluate the effects of maternal voice and white noise on postoperative pain, comfort, and physiological parameters in children aged 1 month to 3 years during the early postoperative period.
The study will also compare the effectiveness of maternal voice and white noise in improving these outcomes.

Detaljeret beskrivelse
For the maternal voice intervention, the mother will select a lullaby, and its lyrics will be provided to her by the researcher. The lullaby will be recorded in the mother's voice with the assistance of the researcher. The sound level of the recording will be adjusted to approximately 50 decibels. Children assigned to the maternal voice group will listen to the recorded lullaby during the early postoperative period. A copy of the recording will be provided to the mother after completion of the study.
Children assigned to the white noise group will listen to the white noise recording "Don't Let Your Baby Cry 2" from the album "Colic." The recording includes intrauterine-like and white-noise sounds combined with music. The recording will be used after obtaining the necessary permissions from the relevant copyright holders.

Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Eksperimentel: Maternal voice
Children received routine postoperative nursing care and listened continuously for 60 minutes to a preoperatively recorded lullaby sung by their mother.
Playback began after baseline physiological measurements following admission to the pediatric surgery ward.
The recording was played through a portable speaker positioned at the head of the child's bed at ear level, with the sound intensity maintained at 50-55 decibels.
|
Before surgery, each mother selected and recorded a lullaby in a quiet room with guidance from the researcher.
Following postoperative admission to the pediatric surgery ward, the recording was played continuously to the child for 60 minutes through a portable speaker.
Sound intensity was monitored using a calibrated sound-level meter and maintained at 50-55 decibels.

Eksperimentel: White noise
Children received routine postoperative nursing care and listened continuously to a standardized white noise recording for 60 minutes.
Playback began after baseline physiological measurements following admission to the pediatric surgery ward.
The recording was played through a portable speaker positioned at the head of the child's bed at ear level, with the sound intensity maintained at 50-55 decibels.
|
Children listened to the standardized recording "Don't Let Your Baby Cry 2" from the album "Colic."
The recording included intrauterine-like sounds, white-noise frequency components, and accompanying music.
It was played continuously for 60 minutes through a portable speaker.
Sound intensity was monitored using a calibrated sound-level meter and maintained at 50-55 decibels.
|
|
Ingen indgriben: Control Arm
Children received routine postoperative nursing care without a structured auditory intervention.
No planned silence or sound restriction was imposed, and the children remained in the usual auditory environment of the pediatric surgery ward.
Outcome assessments were conducted at the same time points as in the intervention groups.

Postoperative Pain Assessed Using the Face, Legs, Activity, Cry, and Consolability Scale
Tidsramme: 30 and 60 minutes after admission to the pediatric surgery ward
|
Postoperative pain was assessed using the Face, Legs, Activity, Cry, and Consolability Scale.
The scale evaluates five behavioral domains: facial expression, leg movement, activity, crying, and consolability.
Each domain is scored from 0 to 2, producing a total score ranging from 0 to 10. Higher scores indicate greater postoperative pain and therefore a worse outcome.
The scale was administered at 30 and 60 minutes.
The prespecified primary endpoint was the total score at 60 minutes.

Postoperative Recovery Assessed Using the Modified Aldrete Recovery Score
Tidsramme: 30 and 60 minutes after admission to the pediatric surgery ward
|
Postoperative recovery was assessed using the Modified Aldrete Recovery Score.
The scale evaluates five domains: motor activity, respiration, circulation, consciousness, and peripheral oxygen saturation.
Each domain is scored from 0 to 2, producing a total score ranging from 0 to 10. Higher scores indicate a better level of postoperative recovery.
A score of 9 or higher generally indicates readiness for discharge from postanesthesia care.
The scale was administered at 30 and 60 minutes.
The prespecified secondary endpoint was the total score at 60 minutes.

Heart Rate
Tidsramme: Immediately after admission and before the intervention, and at 30 and 60 minutes
|
Heart rate was measured using a pulse oximeter and recorded as beats per minute.
Lower values within the age-appropriate physiological range indicate reduced physiological arousal; however, the measure does not have a predefined better or worse direction independently of the clinical context.

Respiratory Rate
Tidsramme: Immediately after admission and before the intervention, and at 30 and 60 minutes
|
Respiratory rate was recorded as breaths per minute.
Lower values within the age-appropriate physiological range may indicate reduced physiological arousal; however, the measure does not have a predefined better or worse direction independently of the clinical context.

Peripheral Oxygen Saturation
Tidsramme: Immediately after admission and before the intervention, and at 30 and 60 minutes
|
Peripheral oxygen saturation was measured using a pulse oximeter and recorded as a percentage.
Higher values within the clinically expected range indicate better oxygenation.
