Women at lower risk of caesarean section when they’re induced: Study
For most women, labour naturally starts between weeks 37 and 42 of pregnancy. When a woman is induced, doctors break her waters and make the uterus contract more strongly to bring on labour deliberately. There’s a variety of reasons why a woman might be induced in this way including that the baby is overdue, that the baby doesn’t seem to be growing well, or that the mother has a health condition that can make labour trickier, like high blood pressure. But the women in the study didn’t have any of those problems, and none had given birth before. The researchers wanted to see whether inducing labour was better than waiting in for women who didn’t otherwise need to be induced for health reasons. Half of the pregnant women were randomly sorted into a group that would be induced at 39 weeks, while the other half would instead go through “expectant management”, where they simply waited for labour to come. The researchers found that women who had a labour induction were 15 per cent less likely to need a caesarean delivery.
