[Physical strain during tocolysis of premature labour (author's transl)]

A group of 29 patients who had premature labour contractions were chosen to take part in this study. All were cardiovascularly healthy. Their performance during a step climbing exercise was examined in relationship to a Fenoterol-tocolysis (30-60 mg/day) and to the amount of exercise. The fetal heart rate showed no pathological changes following the exercise, as compared to the preexercise values. An external tocometry showed the uterine activity also to be uninfluenced.
