The Effect of 3 Different Auditory Applications on Newborn Heel Prick Procedure

In pain management of newborns in interventional applications, health professionals should be able to evaluate pain and reduce or eliminate pain. Pharmacological and non-pharmacological methods are used in the management of pain. Non-pharmacological methods: practices such as breastfeeding, giving a pacifier, giving oral sucrose, listening to music, massage, therapeutic touching and nesting, positioning the fetus such as wrapping, giving kangaroo care, rocking and holding.

The newborn's response to sound often leads to changes in breathing and heart rate. Mild to moderate sounds (55-75 dB), such as speech and music, cause a decrease in heart rate and create an orientation response. Music makes positive changes in oxygen saturation level and heart rate peak values, and also reduces stress and pain. Arnon et al. determined that letting newborns in intensive care listen to music has a positive effect on reducing pain and anxiety, making it easier for newborns to fall asleep and increasing their sleep quality. Classical music with a light rhythmic emphasis and constant rhythm accompanied by a simple human voice or a single instrument, music performed by female vocalists (mother's voice, lullabies with a female voice) and white noise similar to intrauterine sounds are among the types of music that have a positive effect on newborns.

Heel prick pricking in newborns causes pain, which results in increased blood pressure and pulse rate, decreased SpO2, and crying. For this reason, this study was designed as a randomized controlled experimental design to compare the classical music and white noise and lullaby applications to the newborn before and during heel blood collection with the control group and to determine which application provides superior results on the newborn's pain level, crying duration and physiological parameters.

Research Purpose and Type This research was planned as a randomized controlled experimental design to compare the lullaby, classical music and white noise aplications to the newborn during the heel prick prick procedure with the control group.

Research Variables Independent variables; Lullaby your mother sings, white noise, classical music Dependent variables; Heart rate peak (HRV), oxygen saturation (SpO2), NIPS score, NIAPAS score, crying duration.

Place and Time to Conduct the Research The research will be carried out between February 2024 and June 2024 in the Neonatal Intensive Care Unit of Gaziantep Cengiz Gökçek Gynecology and Children's Hospital.

The population of the research It will create term newborns born at 38-42 weeks of gestation in the Neonatal Intensive Care Unit of Gaziantep Cengiz Gökçek Gynecology and Children's Hospital between February 2024 and June 2024. Postpartum 24-72. These are the newborns whose heel blood will be taken during Sample; The sample number of the study was determined by power analysis. The thesis study, which evaluated the effect of different auditory interventions on pain in heel blood collection in newborns, was taken as an example. According to the NIPS pain assessment scale used in the study, the average score of the results during the procedure was 4.26±2.16 in the 1st experimental group, 4.81±2.18 in the 2nd experimental group, 5.02±2.00 in the 3rd experimental group, and 5.93±1.32 in the control group. In this study, it was anticipated that the NIPS score average difference would have a large effect size (.95 large effect), with a 5% alpha margin of error (two-sided) and 80% power, and in the calculation of the number of samples made in the G*Power (3.1.9.2.) program, each It was determined that 20 babies should be included in a group, 80 babies in total. Considering that there may be sample loss for any reason during the research, the aim is to reach 96 newborns (24 babies in each group) by increasing the number of babies by 20% and using statistical parametric analysis methods.

The sample will be randomly selected from the study population. In the study, randomization will be performed using the URN method, which is considered equivalent to the full randomization method. Although this method is shown as UD, it includes two parameters, α and β. These represent balls of two different colors (for example: red and white). α can be white or red, while β will be the exact opposite of the chosen ball colour. One of the balls is chosen randomly, and if the selected ball is white, the subject is assigned to the α group, and if it is red, the subject is assigned to the β group. This selection process is repeated to determine which group the subject will be in.

In the research, the red ball will be the mother's lullaby (intervention group 1), the yellow ball will be white noise (intervention group 2), the blue ball will be classical music (intervention group 3), and the white ball will be the control group. When there is a baby in the clinic that meets the sample selection conditions, these balls prepared by the researcher will be placed in an invisible, dark-colored bag and a random nurse working in the ward will be able to make the selection without seeing it. Which group the baby will be placed in will be determined by the color of the ball coming out of the bag, and the babies will be distributed randomly to the groups.
