| Scientific title | |
| Study acronym | Hypitat (Hypertension and Preeclampsia Intervention Trial at Term) |
| Study objectives | Equivalence between maternal and neonatal outcome. |
| Ethics approval(s) | Approved by the Medical Ethical Committee of the University Medical Centre of Leiden (ref: p04.210) |
| Health condition(s) or problem(s) studied | Pre-eclampsia, pregnancy induced hypertension |
| Intervention | In the intervention group, patients get an induction of labour within 24 hours after randomisation. Patients with a cervix that is judged to be 'ripe' at vaginal examination (bishop score greater than 6), labour will be induced with amniotomy and augmentation with oxytocin. In case the cervix is judged to be 'unripe' (bishop score less than 6), cervical ripening will be stimulated with use of intracervical or intravaginal prostaglandines according to the local protocol. In the expectant group, patients will be monitored until the onset of spontaneous delivery. In this group intervention is recommended in case the foetal or maternal condition does not justify expectant management anymore. As of 06/01/2009, this record was updated to show the completed status based on the participant inclusion completion date of April 2008. The previous anticipated end date of this trial was 01/02/2009. |
| Intervention type | Other |
| Primary outcome measure(s) |
The primary outcome measure will be maternal mortality or severe maternal morbidity. Severe maternal morbidity will be defined as diastolic BP greater than 110 mmHg, major postpartum haemorrhage, eclampsia, HELLP syndrome or abruptio placenta. |
| Key secondary outcome measure(s) |
Secondary outcomes will be neonatal mortality or neonatal morbidity, instrumental delivery rate, severe maternal quality of life and quality of recovery and costs. |
