Early clamping of the cord was one of the first routine medical interventions in labour. Its place in modern births was guaranteed by its incorporation into the triad of interventions that make up the active management of the third stage of labour. The earliest references are clear about the other two components of active management—oxytocin to contract the uterus and prevent postpartum haemorrhage, and controlled cord traction to prevent retention of the placenta.1 But early cord clamping had no specific rationale, and it probably entered the protocol by default because it was already part of standard practice. When this package was shown to reduce postpartum haemorrhage in the 1980s early cord clamping became enshrined in the modern management of labour.
But it has not been accepted everywhere. In Europe, although 90% (1052/1175) of units …
