Induction of labour at 39 weeks
Last month, US researchers found that caesarean section was less frequent in women who had an elective induction at 39 weeks. Sophie Windsor discusses the results
In January 2018, researchers from the Biostatistics Center at George Washington University presented an abstract from the results of A Randomized Trial of Induction Versus Expectant Management (ARRIVE) at the Society for Maternal-Fetal Medicine in the US (Grobman, 2018). The study found that caesarean section was less frequent in women who had an elective induction at 39 weeks (n=569; 18.6%) compared with those who had expectant management (n=673; 22.2%) (risk ratio=0.84% CI 0.76–0.93%).
The aim of this study was to test the hypothesis that elective induction of labour at 39 weeks compared with expectant management among low-risk primiparous women reduced the risk of perinatal mortality and neonatal morbidity.
The researchers concluded that inducing labour at 39 weeks in low-risk primiparous women resulted in a lower instance of birth by caesarean section. They also concluded that there was no significant change in the frequency of a range of adverse perinatal outcomes, such as perinatal death, infection and hypoxic ischaemic encepalophathy.
