Abstract: Objective: To investigate the influence of the different placement of the newborn and the delayed umbilical cord on the outcome of the mother and newborn. Methods: A total of 200 pairs of primiparas and their full-term neonates who were given regular births in a tertiary A hospital in Beijing from June to December 2019 were selected, and they were randomly divided into groups a and b. In group a, after the fetus was delivered, the midwife directly placed the newborn on the delivery bed about 20 cm below the vaginal opening of the mother; in group b, the midwife directly placed the newborn on the mother‘s abdomen (about 15 cm above the level of the vaginal opening) after the fetus was delivered, both group cut off the umbilical cord 60 to 90 seconds after the fetus was delivered. Compare the indicators of two groups. Results: For the parturients, the duration of the third stage and blood loss in the 2 hours after delivery were significantly decreased in group b than group a (P<0.05), and the hemoglobin value on the 1st postpartum was higher in group b than group a (P<0.05). For the two groups of newborns, there was no statistically significant difference in the hemoglobin value, blood pH, transcutaneous bilirubin value on the first and second days after birth, and the incidence of postnatal hyperbilirubinemia in the two groups of newborns (P>0.05). Conclusions: The research method of group b can shorten the time of the third stage of labor of the parturient, reduce the bleeding volume of the parturient 2 hours after delivery, and will not increase the risk of neonatal jaundice. Therefore, it is recommended to place the full-term newborn on the abdomen of the mother and delay cutting the umbilical cord.
