This study explored the effect of synthetic oxytocin on neonatal instinctive breastfeeding behavior. The results showed that with an increase in the dose of synthetic oxytocin, the effect on breast seeking activity and breast attachment was more significant. Additionally, there were differences in exclusive breastfeeding sessions within the first few days after birth, but no statistical difference in exclusive breastfeeding rate at 3 months.
Synthetic oxytocin is the current domestic first-line agent of induced labor and labor augmentation, and its potential effects on neonatal neurobehavioral development is currently attracting increased attention. To explore the effect of different doses of synthetic oxytocin on neonatal instinctive breastfeeding behavior and breastfeeding by observing neonatal behaviors during skin-to-skin contact with mothers after delivery. Observations and comparisons of neonatal instinctive behaviors were conducted by using Widstrom's 9 Stages method. According to the total dosage of oxytocin administered during labor, participants were divided into a low dose group (<= 2.5 U) of 39 pairs, a medium dose group (> 2.5 U) of 38 pairs, a high dose group (> 7.5 U) of 38 pairs and a control group (no synthetic oxytocin use) of 39 pairs. The occurrence time of newborns' instinctive movements and the duration of each behavior stage for the four groups were also analyzed. The number of exclusive breastfeeding sessions within 3 days after birth and the rate of exclusive breastfeeding at 3 months were collected and compared. There were significant differences among the four groups in the occurrence time of raising head or turning head (p = 0.004), eating hands (p = 0.011), moving body (p = 0.001), locating areola (p < 0.001), licking nipples (p = 0.002), containing nipple (p = 0.001), sucking (p < 0.001). There were significant differences among the four groups in the duration of activity (p = 0.004), clawing (p = 0.001), familiarization (p = 0.001), and sucking (p < 0.001). There was also a significant difference in the number of exclusive breastfeeding sessions of 24 h (p = 0.011), 48 h (p < 0.001), 72 h (p = 0.001) after birth among the four groups, but there was no statistical difference in the rate of exclusive breastfeeding at 3 months after birth. The intrapartum administration of synthetic oxytocin was associated with the expression of neonatal instinctive breastfeeding. With increases in drug dose, the effect of breast seeking activity and breast attachment was more significant, and the association of synthetic oxytocin on sucking and breastfeeding was dose-dependent.
