RESUMEN
The report is presented about the treatment of the abortus imminens in the early pregnancy between the 6th and 16th weeks with a new tocolytical substance Th 1165a (Partusisten) on the basis of 61 patients. 40 of the patients reached full term delivery (41 new borns). All new borns except one with multiple chromosomal abnormalities were without any pathological evidence. Two pregnancies terminated into abortion. We could achieve tocolysis in each and every case consistantly by a special worked out scheme. Side effects, which are described due to other beta-adrenergic substances were minimal. Eventual cardiovascular side effects were prevented by additional administration of Isoptin. The results are good. Therefore the administration of Partusisten in the treatment of the imminent abortions in the early pregnancy between the 6th and 16th weeks is sensefull.
