[Measurement of uteroplacental circulation in antihypertensive therapy with clonidine].

40 Gravidae with hypertension were treated with clonidine . Placental blood flow measurements were performed to study the effect of clonidine on uteroplacental blood flow. The results show a significant decrease of the gestosis-index and a significant improvement of placental perfusion type during medication. Therefore, clonidine is suitable for treatment of hypertension in pregnancy and has no negative effect on uteroplacental blood flow.
