ObjectiveTo investigate the effects of individualized intervention on postpartum breast-feeding behavior and satisfaction after cesarean section (CS).Methods341 pregnant women who had cesarean section in West China Second Hospital of Sichuan University from 1st July to 30th August in 2018 were randomly divided into intervention group (171 cases) and control group (170 cases). The participants in experimental group received individualized intervention through the combination of prenatal and postnatal. The participants in control group received routine nursing care. The basic clinical data and breastfeeding information at discharge and day 42 postpartum were compared between the two groups.ResultsThere were no significant differences in age, ethnicity, anesthesia type, preoperative feeding time between the two groups (P>0.05). At the time of discharge and day 42 postpartum, the rate of exclusive breastfeeding, breastfeeding satisfaction and planned breastfeeding duration in the intervention group were higher than those in the control group (P< 0.05). the incidence and degree of breast distending pain, the incidence of cracked nipples, the times of adding formula milk in 24 h, the rate of using feeding bottle and the incidence of feeding problems were all higher in the control group than those in the intervention group (P< 0.05). the knowledge scores of breastfeeding in both groups were higher at discharge than at admission, and the score was higher in the intervention group than that in the control group at the time of discharge.ConclusionThe combination of prenatal and postnatal individualized intervention can significantly improve the knowledge, behavior and satisfaction of breastfeeding.
