[Placental circulation in simultaneous beta-stimulation using hexoprenaline and beta-1 blockade with celiprolol].

In a therapy with Hexoprenalin 0.3 microgram/min an additional administration of Celiprolol (3 X 100 micrograms oral) or Placebo did not change significantly the Placenta perfusion. It remains a question, if an additional therapy with beta 1-mimetic agents is necessary, since Hexoprenalin alone did not change the cardiovascular parameters significantly. This results are not transferable to altered dose or to different betamimetic- and beta blocking agents.
