[Anaphylactoid reactions following administration of plasma substitutes in man. Prevention of this side-effect of haemaccel by premedication with H1- and H2-receptor antagonists (author's transl)].

In a randomized controlled single blind trial in 50 volunteers the problem was investigated whether a combination of dimethpyrindene (0.1 mg/kg b.w.) and cimetidine (10 mg/kg b.w.) could prevent anaphylactoid or allergoid reactions following Haemaccel infusion. In the control group 6 anaphylactoid and 9 allergoid reactions were observed, in the H1 + H2-group, however, none of those reactions occured. No single wheal could be detected. It is considered appropriate to recommend the general use premedication of an H1 + H2-blocker before all anaesthetics and operations. This mainly depends on further clinical trials with the antihistaminic drugs concerning their side-effects under various conditions.
