Maternal obesity is associated with adverse pregnancy outcomes. We routinely see women with a BMI >45 to discuss antenatal and intrapartum care including an early epidural recommendation.


Retrospective analysis of women with a booking BMI >45 between January 2009 and October 2013.


To compare delivery outcomes against the UKOSS study findings and to look at neonatal and anaesthetic outcomes.


These results mirror the UKOSS study findings. Higher maternal BMI is associated with an increased incidence of induction and augmentation of labour. Despite this the vaginal delivery rate is high. Primiparous women requiring induction or augmentation of labour were most susceptible to obstetric intervention. Excluding macrosomia, intrapartum and neonatal complications reflect background population rates.


Our data suggests counselling for an early epidural needs individualising, particularly for multiparous women in spontaneous labour having previously achieved a vaginal delivery.
