Brief Summary

In the 2010-french perinatal survey, the overall cesarean section (CS) rate during labour was 21 % and 16% to 38% in case of dystocia. The definition of " dystocia " is traditionally based on the research led by Friedman in the 1950's on a restricted population sample. Several studies over the last years seem to indicate that the different phases of labour are longer than originally described by Friedman. Our current hypothesis is that the application of a new definition of dystocia would enable a more appropriate management of labour.

    From the admission in the labour ward until the dismissal from maternity (2 to 5 days)

  • obstetrical measures associated with possible effects of both strategies on maternal and fetal outcome

    From the admission in the labour ward until the dismissal from maternity (2 to 5 days)

  • obstetrical measures associated with possible effects of both strategies on maternal and fetal outcome

    From the admission in the labour ward until the dismissal from maternity (2 to 5 days)

  • obstetrical measures associated with possible effects of both strategies on maternal and fetal outcome

    From the admission in the labour ward until the dismissal from maternity (2 to 5 days)

  • +18 more secondary outcomes

Study Arms (2)

Classical partograph

ACTIVE COMPARATOR

Labour dystocia is diagnosed when cervical dilation is less than 1 cm per hour or after 3 hours at complete cervical dilation without engagement of the presentation. In this case, active management of labour is started with introduction of oxytocin, artificial rupture of membranes and supportive therapy.

Other: Classical partograph

New partograph

EXPERIMENTAL

The second strategy is based on the partograph developped by Neal and Lowe. An active management of labour is started when crossing the dystocia line or when there are no cervical modifications after 4 hours beyond 5 cm of cervical dilation. In this case, active management of labour is started with introduction of oxytocin, artificial rupture of membranes and supportive therapy.

Other: New partograph based on the studies of Neal and Lowe

Interventions

The partograph designed by Neal and Lowe includes an "action line" which if crossed permits an active management of labour. Eventually, the only difference between the two arms is the moment when the active management of labour is started. The oxytocin is administrated according to the department protocol.
