Description
Summary:Human breast milk is a natural pain reliever that contains endorphins. The aim of this study was to compare the effects of breast milk and powdered milk on pain severity after a muscular injection in 1-day-old neonates. One hundred neonates admitted to a teaching hospital in Ilam city, Iran, participated in a randomized clinical trial in 2016. One-day-old neonates were divided into four equal groups including: the control group (no feeding); the breastfed group; the bottle-fed mother's milk group and the powdered formula group. All infants received the hepatitis B vaccine by muscle injection in the same position of the thigh. The severity and duration of pain were compared among all groups during and after injection using the DAN scoring method (evaluation behavioral scale of acute pain in newborn infant). One hundred neonates (57% boys) participated in this study. The mean±SD age and weight for participants were 39.15±0.05 weeks and 3016±28g, respectively. Crying duration either during or after the injection in breastfed infants was significantly shorter compared to the control and powdered formula groups (9.2±3.9 and 16±4.6s vs. 38.2±8.9 and 30.0±4.4s, respectively, during injection, P
