Methods: We did an open-label, randomised controlled trial, in seven academic hospitals and 44 non-academic hospitals in the Netherlands.

Background: Gestational hypertension (GH) and pre-eclampsia (PE) can result in severe complications such as eclampsia, placental abruption, syndrome of Hemolysis, Elevated Liver enzymes and Low Platelets (HELLP) and ultimately even neonatal or maternal death. We recently showed that in women with GH or mild PE at term induction of labour reduces both high risk situations for mothers as well as the caesarean section rate. In view of this knowledge, one can raise the question whether women with severe hypertension, pre-eclampsia or deterioration chronic hypertension between 34 and 37 weeks of gestation should be delivered or monitored expectantly.

Design: A total of 83 patients with clinically doubtful rupture of fetal membranes were included, and treated as usual. The clinical diagnosis, the amniotic fluid crystallization test, and IGFBP-1 detection were performed on all patients and compared with the defined gold standard.
