Effect of Three Different Sensory Interventions on Pain Level During Heel Blood Collection in Term Infant

Background: Healthy newborns undergo many painful procedures in the first hours of life. Damage caused by painful procedures can lead to structural and functional changes that can affect adult life. Various non-pharmacological methods have been reported in the literature for pain management. The aim of the study is to investigate the effect of the method that appeals to 3 different senses (mother's voice, breast milk smell, mother's contact) on the level of pain during heel blood collection.

Method: The population of the study consisted of babies who were hospitalized in a hospital's neonatal unit between December 2022 and May 2023 and who heel blood taken. The Neonatal-Infant Pain (NIPS) Scale and data collection form were used to obtain the data. 120 newborns who met the study criteria were randomly divided into group 1 (n=30) , group 2 (n=30), group 3 (n=30), control group (n=30). All intervention was continued 5 minutes before the heel blood collection and continued until the 5th minute after the procedure. The mother called her baby between 40 and 60 decibels loudness for group 1. Breast milk was dripped onto the gauze in an amount to wet the entire 2,5cm*2,5cm sterile gauze and the gauze was then placed close to the baby's nose wings for group 2. Skin-to-skin contact between mother and baby is provided for group 3. NIPS score was saved in 5 minutes before the heel blood collection and continued until the 5th minute after the procedure for all groups.
