Abstract Objective: To analyze the influence of different time of delayed cord clamping (DCC) on maternal and infant outcomes of women with iron deficiency anemia during the third trimester pregnancy. Methods: The pregnant women with iron deficiency anemia during the third trimester pregnancy were selected and were divided into four groups by random number table, which included group A (newborns were performed routine umbilical cord ligation within 10 seconds after delivery), 30 seconds group B (newborns were performed delayed umbilical cord ligation within 30 seconds after delivery), group C (newborns were performed delayed umbilical cord ligation within 60 seconds after delivery), and group D (newborns were performed delayed umbilical cord ligation within 120 seconds after delivery). The clinical data of puerpera and neonates were compared among the four groups. The amount of blood loss within 24h after delivery of women, and the levels of maternal and neonatal hemoglobin (Hb) and hematocrit (HCT) at postpartum 24h in the four groups were analyzed. Results: There were no statistically significant differences in the amount of blood loss of women, and the levels of maternal and neonatal Hb and HCT in 24h after delivery among the four groups (P>0.05). The levels of Hb and HCT of newborn in group D at 72h after delivery were significant higher than those of newborns in other three groups (P<0.05). The neonatal bilirubin level in the first day after birth in group D was significant higher than that of newborns in other three groups (P<0.05), but there was no significant difference in neonatal bilirubin in 2d and 3d after birth among the four groups (P>0.05). There was no significant difference in rate of neonatal phototherapy among the four groups (P>0.05). Conclusion: As for women with iron deficiency anemia during the third trimester pregnancy, the DCC can increase neonatal blood volume and prevent anemia without decreasing maternal blood volume, but newborns accept umbilical cord ligation at 120s after delivery may increase the level of bilirubin in 1 day after birth.
