Clinical Trial 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.

Description:

The main purpose of this study is to show a significant decrease of the CS rate with the use of the new partograph developed by Neal and Lowe. Secondary purposes are - To reduce the use of oxytocin during labour without increasing maternal or neonatal morbidity; - To decrease immediate per-operative complications and post-operative complications associated with CS

Related Conditions & MeSH terms

• Dystocia

Intervention

Other:
• New partograph based on the studies of Neal and Lowe
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.
• Classical partograph
Classical partograph used as standard care
