[Concentrations of local anaesthetics and vasoconstrictor drugs (author's transl)].

By checking the list of local anaesthetics produced in the GDR containing vasoconstrictor drugs it could be proved that there exist disproportions concerning maximum concentrations and maximum doses of the local anaesthetic on the one hand and epinephrine as well as norepinnephrine concentration on the other. This dangerous situation could be changed on initiative of the Society of Anaesthesiology and Reanimation of the GDR.
