[Tocolysis in the first half of pregnancy]

This study includes a total of 60 gravidae with a pregnancy between 8 and 17 weeks of gestation and the signs of threatened abortion (contractions and bleeding). The sonographic examination had shown in 14 patients no gestational sac in the uterus; in 6 patients a deformed gestational sac; in 5 patients a fetus without signs of vitality. In all these patients curettage was performed. In 32 gravidae a therapy seems to be successful: in terms of bedrest and the administration of 0.33 mcg/min Hexoprenaline as a continuous infusion. In only 3 patients an abortion occurred before the end of the 20th week of gestation. In 29 gravidae pregnancy continued undisturbed.
