Abstract

INTRODUCTION: Consensus is lacking regarding the upper limit for a safe contraction frequency during labor. We aimed to assess the association between different contraction frequencies and acidemia at birth, and whether an association was affected by oxytocin augmentation, concomitant cardiotocography (CTG) classification, and stage of labor. MATERIAL AND METHODS: This is a case-control study based on CTG traces from births in southern Sweden during 2012-2017. Cases (N = 364) had umbilical artery pH
