Summary Background Robust evidence to direct management of pregnant women with mild hypertensive disease at term is scarce. We investigated whether induction of labour in women with a singleton ...pregnancy complicated by gestational hypertension or mild pre-eclampsia reduces severe maternal morbidity. Methods We undertook a multicentre, parallel, open-label randomised controlled trial in six academic and 32 non-academic hospitals in the Netherlands between October, 2005, and March, 2008. We enrolled patients with a singleton pregnancy at 36–41 weeks' gestation, and who had gestational hypertension or mild pre-eclampsia. Participants were randomly allocated in a 1:1 ratio by block randomisation with a web-based application system to receive either induction of labour or expectant monitoring. Masking of intervention allocation was not possible. The primary outcome was a composite measure of poor maternal outcome—maternal mortality, maternal morbidity (eclampsia, HELLP syndrome, pulmonary oedema, thromboembolic disease, and placental abruption), progression to severe hypertension or proteinuria, and major post-partum haemorrhage (>1000 mL blood loss). Analysis was by intention to treat and treatment effect is presented as relative risk. This study is registered, number ISRCTN08132825. Findings 756 patients were allocated to receive induction of labour (n=377 patients) or expectant monitoring (n=379). 397 patients refused randomisation but authorised use of their medical records. Of women who were randomised, 117 (31%) allocated to induction of labour developed poor maternal outcome compared with 166 (44%) allocated to expectant monitoring (relative risk 0·71, 95% CI 0·59–0·86, p<0·0001). No cases of maternal or neonatal death or eclampsia were recorded. Interpretation Induction of labour is associated with improved maternal outcome and should be advised for women with mild hypertensive disease beyond 37 weeks' gestation. Funding ZonMw.
Objective The evidence for the management of near term prelabor rupture of membranes is poor. From January 2007 until September 2009, we performed the PPROM Expectant Management versus Induction of ...Labor (PPROMEXIL) trial. In this trial, we showed that in women with preterm prelabor rupture of membranes (PPROM), the incidence of neonatal sepsis was low, and the induction of labor (IoL) did not reduce this risk. Because the PPROMEXIL trial was underpowered and because of a lower-than-expected incidence of neonatal sepsis, we performed a second trial (PPROMEXIL-2), aiming to randomize 200 patients to improve the evidence in near-term PPROM. Study Design In a nationwide multicenter study, nonlaboring women with PPROM between 34 and 37 weeks' gestational age were eligible for inclusion. Patients were randomized to IoL or expectant management (EM). The primary outcome measure was neonatal sepsis. Results From December 2009 until January 2011, we randomized 100 women to IoL and 95 to EM. Neonatal sepsis was seen in 3 neonates (3.0%) in the IoL-group versus 4 neonates (4.1%) in the EM group (relative risk, 0.74; 95% confidence interval, 0.17–3.2). One of the sepsis cases in the IoL group resulted in neonatal death because of asphyxia. There were no significant differences in secondary outcomes. Conclusion The risk of neonatal sepsis after PPROM near term is low. Induction of labor does not reduce this risk.
Objective We sought to study long-term (neuro)developmental and behavioral outcome of pregnancies complicated by intrauterine growth restriction at term in relation to induction of labor or an ...expectant management. Study Design Parents of 2-year-old children included in the Disproportionate Intrauterine Growth Intervention Trial at Term (DIGITAT) answered the Ages and Stages Questionnaire (ASQ) and Child Behavior Checklist (CBCL). Results We approached 582 (89.5%) of 650 parents. The response rate was 50%. Of these children, 27% had an abnormal score on the ASQ and 13% on the CBCL. Results of the ASQ and the CBCL for the 2 policies were comparable. Low birthweight, positive Morbidity Assessment Index score, and admission to intermediate care increased the risk of an abnormal outcome of the ASQ. This effect was not seen for the CBCL. Conclusion In women with intrauterine growth restriction at term, neither a policy of induction of labor nor expectant management affect developmental and behavioral outcome when compared to expectant management.
Objective The Disproportionate Intrauterine Growth Intervention Trial at Term (DIGITAT) compared induction of labor and expectant management in suspected intrauterine growth restriction (IUGR) at ...term. In this subanalysis, we report neonatal morbidity between the policies based on the Morbidity Assessment Index for Newborns (MAIN). Study Design We used data from the DIGITAT. For each neonate, we calculated the MAIN score, a validated outcome scale. Results There were no differences in mean MAIN scores or in MAIN morbidity categories. We found that neonatal admissions are lower after 38 weeks' gestational age compared with 36 and 37 weeks in both groups. Conclusion The incidence of neonatal morbidity in IUGR at term is comparable and relatively mild either after induction or after an expectant policy. However, neonatal admissions are lower after 38 weeks of pregnancy, so if induction to preempt possible stillbirth is considered, it is reasonable to delay until 38 weeks, provided watchful monitoring.
