The influence of present therapeutic methods and especially of beta-blockers on fetal and maternal prognosis in hypertensive syndromes in pregnancy. 43 case records (author's transl)

The authors studied 43 cases of arterial hypertension in pregnancy in an attempt to determine the efficiency and safety of different anti-hypertensive drugs. The patients were divided into two major groups: arterial hypertension which revealed itself during pregnancy (true toxaemias of pregnancy and relapsing toxaemias), and arterial hypertensions which were added on to a pre-existing pathology (arterial hypertension, diabetes, chronic nephritis). The cases in these different classes were then divided into two definite groups according to the need for therapy: the first group was treated by rest and hydrallazine as a single therapeutic agent. In the second group multiple agents were needed because of the arterial hypertension, and one was a beta-blocker. Complications were found particularly in the second group of true toxaemias of pregnancy where unfortunately 5 fetal deaths occurred that were attributable to the severity of the hypertension more than to the beta-blockers, which were administered for longer and in higher doses without major complications in recurrent toxaemias and pre-existing arterial hypertension cases.
