Secher and Karlberg (1962) adopted a method similar to that of Landau et al. (1950). They provided postnatal placental transfusion to infants born by emergency Cesarean section by removing the placenta with the baby without cutting the cord and placing the placenta in a funnel hung above the baby as shown here in the picture from their article. Secher and Karlberg noted, as had Landau et al.: "Late clamping of the cord has been an accepted rule in normal deliveries" [7, p1203]. Thus into the 1960s it was recognized that placental circulation normally continues after birth, and should not be abruptly terminated by use of a clamp on the umbilical cord.
