During labour, the baby requires frequent monitoring of the heartbeat to detect fetal distress. A premature baby’s skull is prone to excess moulding or bruising and it is preferable not to break the waters because the intact membranes protect the baby’s head from pressure by the cervix when the uterus contracts. Pethidine injections are avoided because a small baby may be very sensitive and the drug may depress breathing at birth, and epidural anaesthetic is preferable to diminish the effect of the anaesthetic drugs on the baby. A Caesarean Section may be needed if the baby is in the breech position or shows signs of distress.
