[Plasma volumetry with 131I in gestoses of different degrees of severity with dystrophy in children].

Plasma volume was measured with 131I-marked human albumin in 32 cases of gestosis at 35 to 38 weeks gestation. The same tests were made in 4 nonpregnant women. We examined 24 patients suffering from medium to severe gestosis (above 4 points according to Goecke) and 8 patients suffering from minimal gestosis (under 4 points). 4 nonpregnant women exhibited a mean plasma volume of 41.3 ml kg body weight, whereas patients suffering from minimal gestosis exhibited a mean plasma volume of 51.5 ml/kg body weight, in those suffering from medium to severe gestosis we found a volume of 48 ml/kg body weight. There was no significant correlation between the severity of the gestosis and plasma volume reduction, in contrast to birth weight of the infant with regard to gestation period and plasma volume. A low plasma volume in the mother was closely correlated to fetal dystrophy. The sensitivity of the method was 88.8%, specificity 80%.
