Abstract: Objective To explore the effect of breast milk donation (DHM) feeding support intervention on the prognosis of mothers and infants of high risk pregnant women. Methods The clinical data of 120 cases of high risk pregnant women admitted to our hospital from September 2017 to September 2019 were retrospectively analyzed. According to whether the family members agreed to give DHM to infants, the mothers and infants were divided into observation group (64 cases) and control group (56 cases). The observation group received DHM feeding support intervention, while the control group received formula feeding. The incidence of breast distention within 3 days after delivery was compared between the two groups. The lactation rate of postpartum 1,2 and > 3 days, the rate of pure breast feeding within 6 weeks after delivery, and the neonatal development after 7 days were compared between the two groups. Results (1) Within 3 days after delivery, the incidence of breast distention in the observation group was 12.50%(8/64), which was lower than 28.57%(16/56) in the control group(P<0.05). (2) After using DHM, the number of lactation women in the observation group was higher than that in the control group on the first day after delivery. The number of lactating women in the observation group two days after delivery and the number of nonlactating women 3 days after delivery in the observation group were lower than those in the control group(P＜0.05). (3) The rate of pure breastfeeding in the observation group was 75.00%(48/64), which was higher than 57.14%(32/56) in the control group, the difference being statistically significant(P＜0.05). (4) The rate of normal defecation in the observation group was higher than that in the control group, the rate of abdominal distension was lower, and the growth of body weight was higher than that in the control group, and the difference was statistically significant (P＜0.05). Conclusion DHM feeding intervention support can help high risk pregnant women to reduce milk distension, promote early lactation, help mothers implement early exclusive breastfeeding, reduce the incidence of abnormal stool and abdominal distension, and promote the growth of neonatal body weight.
