RESUMO
Delayed umbilical cord clamping and umbilical cord milking could promote blood flowing from the placenta to the newborn, which would increase neonatal blood volume, avoid suddenly cardiac preload changes caused by the interruption of placental transfusion at birth, and make the neonatal cardiovascular system transition more stable and physiological.Although there have been cases of neonatal jaundice and polycythemia caused by placental transfusion in clinical, studies have shown that placental transfusion does not increase the incidence.At present, umbilical cord clamping immediately after birth is the commonly clinical practice in most countries, including China.The method of umbilical cord clamping, the factors effecting placental transfusion and the pros and cons of placental transfusion still need further research.
