The Labour Progression Study, a Cluster Randomised Trial on Labour Progression for First Time Mothers

Guideline which takes into account the dilatation of the cervix on admission and calculates the expected progression during the active phase of the first stage of labour based on this finding. Labour dystocia in the second stage of labour is diagnosed if lasting longer than two hours and 45 minutes, three hours and 30 minutes for women with epidurals or if the expulsion phase lasts longer than 60 minutes. This guideline is based on the labour progression curve by Zhang.
