Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Premature baby with corrected gestational age (CGA) between 27 to 35 weeks period of gestation (POG). CGA is calculated as POG plus current age of baby in weeks.

Subject will be exposed to recording of their mothers voice for 10 minutes every day for 2 weeks.

Their mother will be given a recorder prior to the study, she will be asked to record her voice in any form i.e. singing, talking,rhyming, reading for 10minutes.

The same recording will be played to their babies daily for 2 weeks.

The recording will be played during daytime, after feeding was given.

The volume of the sound will be kept at 50-55dB as recommended by American Academy of Paediatrics.

Their biophysical parameter (Heart Rate, Respiratory Rate, SPO2) and neurobehavioral score will be monitored pre, during and post intervention daily.

Outcomes
Primary outcome [1] 295199 0
To determine the effect of maternal voice vs NICU environmental sounds on physiological measures in premature infants.

The physiological changes measured are changes of Heart Rate (HR) , Respiratory Rate (RR), SPO2 in infants exposed to mother’s voice vs NICU environmental sound.

It is measured by using probe attached to recording monitor (Phillip Intellivue MP70).
Timepoint [1] 295199 0
Every 1 minute during 10 min pre, 1 min during and 1 min post intervention.
Primary outcome [2] 295404 0
To determine the effect of maternal voice vs NICU environmental sounds on behavioral measures in premature infants.

Neurobehavioral score is done by using Behavioral Indicators of Infant Pain (BIIP) score adapted from HOLSTI, L. & GRUNAU, R. E. (2007). It is a score that is using facial and hand coding that indicate infants pain.
Timepoint [2] 295404 0
Every 10 minute during 10 min pre, 10 min during and 10 min post intervention daily
Secondary outcome [1] 315028 0
To compare mean changes of Heart Rate (HR)in infants exposed to mother’s voice vs NICU environmental sound.
It is measured by using probe attached to recording monitor (Phillip Intellivue MP70).
Timepoint [1] 315028 0
Every 1 minute during 10 min pre, 10 min during and 1 min post intervention.
Study will be done daily for 2 weeks.
Secondary outcome [2] 315029 0
To compare mean weight gain between premature infants exposed to mother’s voice vs NICU environmental sound

Subject's weight will be measured on a standard digital weighing machine in NICU (SECA 728 baby scales)
Timepoint [2] 315029 0
After 14 days from date starting study
Subject's weight will be measured every alternate day for 2 weeks during study period.
Secondary outcome [3] 315030 0
To compare mean neurobehavioral score between premature infants exposed to mother’s voice vs NICU environmental sound

Neurobehavioral score is done by using Behavioral Indicators of Infant Pain (BIIP) score adapted from HOLSTI, L. & GRUNAU, R. E. (2007). It is a score that is using facial and hand coding that indicate infants pain.
Timepoint [3] 315030 0
Every 10 minute during 10 min pre, 10 min during and 10 min post intervention.
Study will be done daily for 2 weeks.
Secondary outcome [4] 315674 0
To compare mean changes of Respiratory Rate (RR) in infants exposed to mother’s voice vs NICU environmental sound.
It is measured by using probe attached to recording monitor (Phillip Intellivue MP70).
Timepoint [4] 315674 0
Every 1 minute during 10 min pre, 10min intervention, 10 min post intervention
Secondary outcome [5] 315675 0
To compare mean changes of SPO2 in infants exposed to mother’s voice vs NICU environmental sound.
It is measured by using probe attached to recording monitor (Phillip Intellivue MP70).
Timepoint [5] 315675 0
Every 1 minute during 10 min pre, 10 min intervention, 10 min post intervention

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed as randomization is created using computer software and allocation is sealed in opaque envelope and only will be open on the day of study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Using computer software -randomizer.org

Statistical methods / analysis
Based on previous study by (Alipour et al., 2013), the sample size to achieve a power of 0.8, alpha level of 0.05, and the mean difference of 5 with standard deviation of 9.57 for physiological responses was 58 per group is needed. Therefore, total sample size of 140 is needed with 20% drop out.
(ALIPOUR, Z., ESKANDARI, N., HOSSAINI, S. K. E. & SANGI, S. 2013. Effect of vocal stimulation on responses of premature infants. Health, Spirituality and Medical Ethics,)

All data will be entered and analyze using SPSS version 18.

Descriptive analysis:Mean (SD) , Median (IQR) will be used to describe numerical data while number and percentage will be used for categorical data.

Independent t test and Chi Square test will be used to compare the demographic numerical and categorical data accordingly.

Repeated Measure ANOVA will be used to compare the difference in mean of the dependent variable between pre and post intervention group
