Magnesium therapy decreased the rate of intrauterine fetal retardation, premature rupture of membranes and premature delivery in risk pregnancies treated with betamimetics.

A higher percentage of intrauterine growth retarded (IUR) infants was found in patients treated with tocolytic drugs, indicating that placental insufficiency could be the cause of both premature labor and IUR. In order to evaluate the results of oral treatment with betamimetics and magnesium at different dosages, 534 (10.9%) pregnancies treated with tocolysis + cerclage (TC) of 4,905 single pregnancies managed in our hospital between 1979 and 1982 wee studied retrospectively. Addition of magnesium to betamimetics: since 1979/1980 3-6 mEq Mg2+ daily per os aimed towards 'cardioprotection', and since 1981, to 'support tocolyis' 30-40 mEq Mg2+ daily per os in the form of Mg aspartate. We compared: mean age, parity, percentage supplemented with Mg and outcome of pregnancy for each year; these parameters were also compared with those of normal pregnancies. The frequency of (completed) gestational periods less than or equal to 36 weeks was about 11% in the TC groups (only 2% in normal pregnancies). However, this was reduced annually from 11.0% in 1979 to 4.9% in 1982. The frequency of premature ruptured membranes (PROM) in premature infants was about 6% in the TC groups from 1979 to 1980. It was reduced to 2.2% in 1981 and to 1.6% in 1982 (normal pregnancies, about 1%). In the TC group the frequency of IUR (less than 10th percentile; Bavarian Perinatal Evaluation; BPE) amounted to 20.5% in 1979, and to 17.5% in 1980. It was reduced to 8.8% in 1981 and to 10.6% in 1982 (normal groups, between 8.3 and 11.5%).(ABSTRACT TRUNCATED AT 250 WORDS)

[Reduced frequency of gestoses in beta-mimetic treated risk pregnancies with added magnesium therapy].

Retrospectively the 4,905 single pregnancies of the four years 1979-1982 are divided into 882 (18.0%) patients treated by tocolysis and 4,023 (82.0%) patients treated without tocolysis (R). The patients with tocolysis (BMG) received in addition to the Betamimectic agents since 1979 a low dose of magnesium (feto- longoral ) to protect the heart (3-6 mval Mg ++) daily and since early in 1981 to assist in the tocolysis 30 to 40 mval Mg ++ daily in the oral from of magnesium aspartate (Mg 5- Longoral ). The incidence of pre-eclampsia (G) in the groups BMG and R is recorded. The R group constitutes the normal group (N) by substracting the group G. Compared were in the groups NG and BMG the mean age and parity, the incidence of adjuvant magnesium medication, the duration of pregnancy and the incidence of intra-uterine growth retardation ( IUR ). The incidence of pre-eclampsia (G) in the 882 patients treated with Betamimetics and magnesium was 0. In the other 4,093 patients the incidence was 97 (2%). The rate of intra-uterine growth (lower than the 10% BPE ) was 9.4% in the 3,093 normal patients, 45.4% in the 97 patients with pre-eclampsia and in the 398 BMG patients of the years 1979 and 1980 with the small addition of magnesium (BMG 1) the incidence was 17.8%. In the 484 patients of the years 1981 and 1982, with large additional doses of magnesium (BMG 2) the incidence was 10.1%. The correlation of the intra-uterine growth retardation degrees (lower than 25% Hohenauer , 10% BPE ) was highest in the group G (1.3:1).(ABSTRACT TRUNCATED AT 250 WORDS)

[Successful further prolongation of immature twin pregnancy by tocolysis and re-cerclage following unavoidable delivery of the first foetus after emergency cerclage (author's transl)].

The article reports on a twin pregnancy with EPH gestosis in a 20-year old primipara which could be prolonged by tocolysis and emergency cerclage after signs of premature delivery and prolapse of the amniotic sac in the 28th/29th pregnancy week. At the beginning of the 30th gestation week there was an unavoidable delivery of the first twin (920 g) who survived for 5 days only due to immaturity and hypotrophy. Directly after delivery of the first twin the pregnancy for the second twin was prolonged by renewed tocolysis and renewed circular suture of the cervix. This enabled the second child, whose growth had been retarded like that of the first one, to continue to grow for some time. Unavoidable delivery of the second twin (1,650 g) eventually occurred at the beginning of the 32nd week of pregnancy. The eutrophic child survived without the slightest complication. This case is presented in detail and discussed, including the histology of the placenta. The most important points for enabling the survival of a twin foetus are sufficient tocolysis, a satisfactory technique for occlusion of the os uteri, as well as exclusion and prevention of chorioamnionitis.

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

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).

[The use of partusisten in the delivery of triplets with an incarcerated fetus (author's transl)].

A triplet delivery is reported. The multiple pregnancy was undiagnosed prior to labor. Twins were diagnosed on admission for delivery. The ultrasonic and abdominal EKG findings at term are discussed. The hitherto undiagnosed third triplet became incarcerated following the administration of two units of syntocinon after the delivery of the second triplet. The intrapartum tocolysis with partusisten became life saving for the third triplet on three counts. 1. The progressive acidosis was stopped. 2. Time was gained to prepared for delivery of the last triplet. 3. Internal podalic version and extraction was much easier.

[Alpha 1 fetoprotein in pre-eclamptic toxemia (author's transl)].

From 1973 to 1975, 287 serum levels of alpha 1 fetoprotein in women with pre-eclamptic toxemia were determined. Pre-eclamptic toxemia was classified according to modified scheme of Goecke and Rippmann. 161 patients had mild pre-eclamptic toxemia (index 1-3), 72 patients had moderate pre-eclamptic toxemia (index 4-6), 54 patients had severe pre-eclamptic toxemia (index 7). In all types of severity of pre-eclamptic toxemia more levels of alpha fetoprotein were lower or higher than the normal levels including the standard deviations. The number of abnormal values rose with an increasing toxemia index. There was no statistically significant difference between too high values and too low values. Significantly more values were above and also below the normal values. Our investigations appear to indicate that the determination of the alpha fetoprotein is not only valuable as screening method for neural tube defects but also of value in the diagnosis and management of pre-eclamptic toxemia. Too high and too low values should not be differentiated but values both above and below the normal levels should be considered.
