    • Abstract:
      To determine risk factors for confusion between maternal heart rate (MHR) and fetal heart rate (FHR) while pushing in the second stage of labour, a prospective historical cohort including 300 singleton birth at term was conducted at Grenoble University maternity clinic. Confusion between MHR and FHR occurred in 65% of cases. The median percentage of confusion was 34.5% of the pushing tracings. Three elements were significantly correlated to confusion: epidural analgesia, which lowers the percentage of confusion, maternal tachycardia and obesity, which both enhance the confusion percentage. No consequences of confusion with regards to the neonatal state could be established. The instrumental delivery rate was significantly lower when the percentage of confusion increased. FHR monitoring using external captors during pushing appears to be of limited help to assess the fetal wellbeing as the percentage of confusion with MHR remains high. [ABSTRACT FROM AUTHOR]
