[A test for early detection of hypertonias conditioned by pregnancy (gestosis selection test - GST) (author's...

72 patients were subjected to the gestosis selection test (= GST) during the 28th (+/- 3 weeks) week of pregnancy in the sense of a "screening" with regard to potential risk of gestosis. A detailed description of GST, which consists of the injection of a bolus of fenoterol is given. Depending upon the possibility of reducing the diastolic blood pressure, 2 groups of pregnant women can be distinguished with regard to the prospective assessment of the course of pregnancy: GST Group I: The diastolic blood pressure can be reduced by 30 mmHg and more - Development of gestosis is hardly probable. GST Group II: The diastolic blood pressure can be reduced by less than 30 mmHg - Development of gestosis probable. Of the prospectively examined 72 patients, 40 have meanwhile delivered. There was no gestosis in group I, whereas in group II there were 8 gestoses. The GST is compared with other screening methods based on blood pressure which were also carried out at the same time: the "roll over test" (ROT) as well as calculation of the mean arterial blood pressure during the second trimenon (MAP-2).
