Abstract

Objective To assess the pregnancy outcomes of women cared for in a dedicated bariatric clinic. This will include mode of delivery, complication rates, induction rates and neonatal outcomes.

Study Design This is a retrospective cohort study of 105 patients between January and July 2008. Computerised medical records and CRIS (ultrasound database) were used to retrieve demographics and obstetric information.

Results 105 women had a BMI greater than 35, 85% had a BMI between 35 and 45, and 15% had a BMI greater than 45. The Caesarean section rate was 34.3%, with 44% of these being elective (63% indication was previous caesarean section) 58% of women had a normal vaginal delivery and the instrumental delivery rate was 6.7%. Fetal heart monitoring was continuous only 46% of the time. 41% of cases were induced and 41% of cases had spontaneous labour, from the spontaneous labourers only 1% had an emergency caesarean section, in the induction group 30% had an emergency caesarean section (35% indication was delay/failed induction). Postpartum haemorrhage occurred in 9% of women and shoulder dystocia in 2%. 31.9% of women who had a vaginal delivery had an intact perineum with 1 third degree tear reported. For term deliveries (37 weeks onwards) the birth weights ranged from 2310g to 5170g (8% greater than 4500g). 3.8% of babies had apgars of less than 7 at 10 min. Comparison with hospital averages will be presented.
