Hypertensive crisis in patients with severe pre-eclampsia needs to be treated to prevent maternal and fetal complications. The maternal, uteroplacental and fetal haemodynamic respose to antihypertensive treatment with Nicardipinehydrochloride will be evaluated in detail by materal echocardiography and fetal doppler ultrasound as well as by the effect on plasma Brain Natriuretic Peptide concentration (BNP) and parameters of the Renin- Angiotensin- Aldosterone system (RAAS). MedDRA version: 9.1

| Main Objective: To investigate in detail the haemodynamic effects of antihypertensive treatment with Nicardipine of a hypertensive crisis in patients with severe pre-eclampsia. The effects will be investigated by maternal cardiac ultrasound and doppler ultrasound of the uteroplacental and fetal circulation.;Secondary Objective: The effects of Nicardipine treatment of a hypertensive crisis in severe pre-eclampsia on the plasma Brain Natriuretic Peptide concentration and parameters of the Renin-Angiotensin-Aldosterone system as well as the correlation of these parameters with the maternal haemodynamics ;Primary end point(s): blood pressure maternal cardiac function (systolic, diastolic) uteroplacental and fetal doppler BNP RAAS | — |
