[Cardiotocogram findings in antenatal monitoring of fetal hematoblastosis and during intrauterine intrafetal transfusion].

34 falls with Morbus haemolyticus fetalis were controled from the 30. to 40. week of pregnancy by cardiotocography. The order of the severity of fetal erythroblastosis and certain types of oscillation devoted: In slight cases of Morbus haemolyticus fetalis preponderated (Hb greater than 15 g%) a undulating curve of oscillation (80%). Middlesevere cases (Hb 9-15 g%) showed in 57.2% an undulating and in 42.8% a saltatoring types of oscillation. In cases of severe fetal anemia (Hb less than 9 g%) we found at 64.2% a silent to narrowed undulating and at 21.4% saltatoring types of oscillations. A normal type of oscillation we not observed in this group. The various degrees of a chronical fetal hypoxia caused by an anemia and a placental dysfunction have been discussed as a reason for the typical CTG-curves. At hydrops fetus et placentae are bearing silent and sinusoid heart frequency curve and the CTG-sign late deceleration. A fetal intrauterine transfusion seems not very successfully, at this findings. During the intrauterine transfusion were established in all cases to a restriction of fluctuation at simultaneous increase of frequency.
