Brief summary

Active phase of the second stage of labor corresponds to period of maternal expulsive efforts (i.e. pushing). An intensive management of this phase is usual in France. This study aims to evaluate the impact of an alternative moderate management during this pushing phase on neonatal and maternal issues and mode of delivery.

Detailed description

Management of the active phase of the second stage of labor is not an evidence-based practice. Management of this phase differs between countries. In France, national guidelines recommend to limit maternal expulsive efforts to 30 minutes (grade C). Thus, physicians (midwives and obstetricians) encourage usually women to push 3 times per contractions and to push on every contraction in order to deliver into a 30 minutes timing. This study aims to evaluate the impact of an alternative moderate management during this pushing phase on neonatal and maternal issues and mode of delivery. In the intervention group, i.e. moderate pushing, women are encouraged to push only 2 times per contractions, to respect contractions without pushing and there is no limit of pushing duration. The hypothesis is that moderate management of the active phase of the second stage allows decreasing frequency of neonatal morbidity at birth, decreasing frequency of operative delivery and increasing maternal satisfaction.

Interventions

PROCEDUREModerate management

After randomization, women allocated to the intervention group, i.e. moderate pushing, are encouraged to push only 2 times per contractions, to respect contractions without pushing and there is no limit of pushing duration.

This group corresponds to usual obstetrical management of active second stage in France. In France, national guidelines recommend to limit maternal expulsive efforts to 30 minutes (grade C). Thus, physicians (midwives and obstetricians) encourage usually women to push 3 times per contractions and to push on every contraction in order to deliver into a 30 minutes timing.
