The effect of Maternal hearing the sound on Non Stress Test(NST) results

Determining the effect of hearing sound on stress test results

The present study will be performed as a control trial with a control group, randomly based on purpose, three-blinds, which will be performed on 106 pregnant women with a gestational age of 32-42 weeks of gestation with inclusion criteria

The present study will be conducted in Asali Teaching Hospital, people will be randomly divided into two groups of intervention and control. In the intervention group, after ensuring the health of the auditory canal using a special music headset during the non stress test, which lasts 20 minutes, will be played(It should be noted that the type of music and the degree of sound will be the same in all samples of the intervention group), and in the control group, under the same conditions, normally without playing test music without Stress will be taken.

Inclusion criteria: Auditory canal health, Gestational age 32-32 weeks, Single pregnancy with healthy fetus, No symptoms of childbirth, No smoking, drugs or sedatives and drugs that cause maternal depression./Exclusion criteria: Multiple pregnancy, Maternal fasting, Decreased amniotic fluid volume (oligohydramnios based on ultrasound evidence)

Listening to music with a headset in the intervention group during the non stress test of fetal heart rate

After the end of the Non StressTest (end of 20 minutes), the results of the non stress test included the baseline fetal heart rate, number of fetal movements, number of accelerations,Beat-to-Beat variability, and the time to reach the reactive NST will be checked.Anxiety scores are also determined based on the Spielberger questionnaire. And all the outcomes are compared in the two groups of intervention and control.

Randomization was simple with no substitution, so that two cards with numbers one and two, each of which represented the intervention and control group, were given to the first person,She, after selecting one of the cards. She entered the relevant group and the second person was automatically assigned to the opposite group of the previous person and again the cards were presented to the third person for selection and thus continued until the sampling was completed.

In this study, which was performed in three-way blinds, a researcher colleague was used to randomly allocate samples to blind the researcher. After entering the special room for NST, the samples were performed by a fellow researcher to establish the sound of music, and for the control group, a headset device without playing music was placed on the ear of the control group, Therefore, the researcher was not able to distinguish the two groups of intervention and control. Finally, in order to evaluate and interpret the results of the study, which was performed by three people, including the researcher, a gynecologist and a reproductive health specialist, all individuals were unaware of the placement of the samples in the intervention and control groups. The data analyzer, who had the groups as the names of groups 1 and group 2, was unaware of the main nature of groups 1 and 2.

All research results and data will be provided to Asali Educational Center and University

In this plan, it is possible to access the results Six month after the final analysis of the data and the final report to the University of Medical Sciences

Vice Chancellor for Research and Technology of the University, Asali Teaching Hospital, which is the place of research, and also those involved in the medical equipment industry to use the research results to upgrade the external fetal heart monitoring device.
