ABSTRACT
PURPOSE: This study aimed to evaluate the effect of delayed lactogenesis II on early milk volume in mothers expressing milk for their preterm infants. METHODS: 142 mothers with preterm infants participated in a longitudinal cohort study, the milk volumes over 14 days postpartum between mothers with delayed lactogenesis II (≥ 72 hours) and mothers with non-delayed lactogenesis II(< 72 hours) were compared using Wilcoxon's rank sum tests. RESULTS: The prevalence of delayed lactogenesis II among mothers of preterm infants was 36.0% (36/100). There existed negative correlations between the onset of lactogenesis II and the daily milk volumes(r(s) = −0.525~−0.354, p = .002 ~ p < .001). The milk volumes in every 24-hour of the 14 days postpartum in delayed group were significantly less than that in non-delayed group (p = .002 ~ p < .001). After controlling for the covariates, pregnancy-induced hypertension syndrome, delayed expression initiation, shorter daily sleeping time were found to be the risk factors for delayed lactogenesis II. CONCLUSION: Delayed lactogenesis II was associated with lower milk volume in early postpartum period. Women who were at risk for delayed lactogenesis II need targeted interventions and additional support during pregnancy and postpartum.

Objective To analyze the influence of the cesarean section and vaginal delivery at term pregnancy when fetal distress in labor conditions on maternal and neonatal outcomes .Methods 238 cases of fetal distress in labor when full-term pregnant were selected ,and they were randomly divided into the observation group and control group,119 cases in each group .The control group was given midwifery vaginal delivery ,while the observation group was given cesarean section .The maternal and neonatal outcomes were compared between the two groups . Results 78 cases(65.55%) of neonatal score above 7 or more points and 7 or more points of the control group were 58 cases(48.74%),the difference was significant (P<0.05).The incidence rate of neonatal complications in the observation group was 5.88%, which was significantly lower than 20.16% of the control group ( P <0.05 ). Conclusion Fetal distress in full-term pregnancy in labor , the use of cesarean section has higher neonatal score compared with vaginal delivery ,and it has low incidence rate of neonatal complications ,it is worth to be applied in clinical.
