Timing of planned repeated caesarean section: An enigma

Summary

We aimed to explore the current trends among obstetric consultants in timing planned caesarean sections in patients with previous caesarean deliveries. A questionnaire was sent to 129 consultant obstetricians and gynaecologists. The questionnaire included closed questions about the preferred gestational age to perform an elective caesarean section in patients with previous one, two, three or more caesarean deliveries and in patients with a previous classical caesarean scar. The study was confined to NHS hospitals at the Eastern and London Deaneries, UK. The main outcome measure was the gestational age at which a planned caesarean section was preferred. The percentage of consultants who preferred to do caesarean section at 39 weeks or more gestational age in patients with previous one, two, three or more and a classical caesarean section were 93.6%, 87.3%, 71.3% and 35.9%, respectively. A considerable body of obstetricians plan to perform elective caesarean sections at a gestational age <39 weeks in patients with three or more previous abdominal deliveries and in patients with a previous classical caesarean section. There are no randomised controlled trials to address the best practice in these cases. Looking at the available evidence in the literature, it seems unjustified to perform the caesarean section at an earlier gestational age for patients with previous multiple caesarean sections but there is some evidence to support this policy in patients with a previous classical section.
