Induction may lower caesarean risk
The study, which involved data from 157 randomised controlled trials, found that overall the risk of a caesarean delivery was 12% lower in women whose labour was induced compared to women who went into spontaneous labour. The effect was significant in term and post-term deliveries but not in pre-term labour.
Furthermore, the analysis showed that initial cervical dilation and the reason for induction did not alter the result.
Women experiencing uncomplicated pregnancies who were induced at term (after 38 weeks) or post-term without a medical indication for induction had a 19% reduced risk of caesarean delivery compared to peers who were expectantly managed.
In terms of the method of induction, the most significant risk reduction was found for the use of prostaglandin, although risk reductions were also found for misoprostol, alternative methods (including acupuncture) and mixed methods that combined pharmaceutical and mechanical
