    Practical advice on providing resuscitation of the neonate with an intact cord

    Physiologically based cord clamping stabilises cardiac output and reduces cerebrovascular injury in asphyxiated near-term lambs.

    Polglase and colleagues have shown that in near term asphyxiated lambs physiologically based cord clamping (PBCC) may be a more suitable option for the resuscitation of the asphyxiated newborn compared with the current standard practice of immediate cord clamping (ICC). This inevitably requires that the newborn remains close enough to its mother for the cord to remain intact. They showed evidence that brain injury was greatly reduced compared with ICC followed by resuscitation. This study in lambs suggests that delayed cord clamping may benefit most human infants, term and preterm, healthy and asphyxiated. Readers will wish to know how it is possible in practical terms to provide resuscitation at the side of the mother with an intact cord and this information is available from Katheria et al (1) and Batey et al (2).
