[The influence of norephedrinetheophylline-noradrenalinetheophylline on the orthostatic disturbance of the circulatory regulation in children (author's transl)].

In 20 children with orthostasis syndrome of the sympathicotonic type of cardiac and circulatory parameters were studied with sphygmography according to Broemster-Ranke and the time values of cardiac action according to Blumberger for 10 minutes both in horizontal and vertical positions (reclinable tabel 65 degrees). These tests were done prior to and 30 minutes after application of 1 tablet of Akrinor and following four weeks of treatment with 1 tablet Akrinor/die. In comparison to orthostasis tests without medication we found after application of Akrinor an increase in the amplitude of blood pressure and cardiac output, a reduction of the excessive centralization together with a decrease in the resistance of the peripheral vessels. The time values, lengthened due to orthostasis, are shortened.
