Elective repeat caesarean delivery before 39 weeks of gestation is
Common. This study investigated associations between elective caesarean
delivery at 37-39 weeks of gestation and neonatal outcomes, in a cohort
of women with viable singleton pregnancies having a repeat caesarean
section at 19 centres in the USA from 1999 to 2002. Risk of neonatal
death, respiratory complications, hypoglycaemia, newborn sepsis, and
admission to the neonatal intensive care unit were studied. Of 24,077
repeat caesarean deliveries, 13,258 were performed electively, of which
6.3% were delivered at 37 weeks, 29.5% at 38 weeks and 49.1% at 39 weeks
of gestation. One neonatal death occurred. As compared with births at 39
weeks, births at 37 weeks and 38 weeks were associated with an increased
risk of neonatal death (adjusted odds ratio for births at 37 weeks, 2.1;
adjusted odds ratio for births at 38 weeks, 1.5; p for trend<0.001).
The rate of adverse events in the newborn was increased by a factor of
1.8 to 4.2 for births at 37 weeks and 1.3 to 2.1 for births at 38 weeks.
Because of increased rates of respiratory complications and other
adverse neonatal outcomes, elective caesarean section should be
discouraged before 39 weeks of gestation. (1)
