The use of a cervical dilatation graph in the management of primigravidae in labour.

One thousand consecutive labours in primigravid patients were evaluated to show the value of the combined use of a cervical dilatation graph and a policy of active management. Intervention was required at a significantly higher rate in patients with abnormal cervical dilatation patterns. Significantly more Caesarean sections were performed in patients with abnormal cervical dilatation pattern. Early recognition of cervical dilatation problems, early intervention, and the avoidance of difficult vaginal deliveries have contributed to the good results.
