The pulsating umbilical cord

    Frischkorn and Rucker (1939) described the appearance of the unclamped
    umbilical cord.  Even in the 1930s cessation of pulsations was no longer
    waited  for by all obstetricians:

    "If a cord be watched immediately after delivery the umbilical
    vessels can be seen to pulsate strongly throughout their entire
    length.  In a varying length of time the pulsations cease in the
    more distal part and as this occurs the umbilical vessels collapse.  
    This process of cessation of pulsation and collapse of the vessels
    proceeds toward the umbilicus until finally there is no pulsation
    even at the navel.  The vessels are then entirely collapsed.  If
    now the cord be tied and cut very little blood will escape from the
    placental end." [3, p 593]
