متن کاملPlacental blood transfusion in newborn babies reaches a plateau after 140 s: Further analysis of longitudinal survey of weight change

There is no agreement, however, on how long the delay should b...
متن کاملRethinking placental transfusion and cord clamping issues.
A brief delay in clamping the umbilical cord results in a placental transfusion that supplies the infant with a major source of iron during the first few months of life. Cord circulation continues for several minutes after birth and placental transfusion results in approximately 30% more blood volume. Gravity influences the amount of placental transfusion that an infant receives. Placing the in...
