The randomized controlled and experimental study was conducted with 60 newborns applied to a public family health center for heel blood collection. The infants in the experimental group (n=30) were listened to the maternal heart sound before, during, and after the heel blood collection procedure, and routine blood collection was applied to the control group (n=30). Newborn Information Form and Newborn Infant Pain Scale (NIPS) were used to collect data.
This study was carried out to determine the effect of maternal heart sound listened to by newborns during heel blood collection on pain level and crying time.
