Maternal body mass index and oxytocin in augmentation of labour in nulliparous women: a prospective observational study.

ABSTRACT:

Objective

To evaluate oxytocin use for augmentation of labour in relation to body mass index (BMI) on admission to the labour ward, focusing on cumulative oxytocin dose and maximum rate of oxytocin infusion during the first stage of labour.
