Effect of catecholamines and sympatholytics on survival and circulatory parameters in protracted anaphylactic shock of guinea pigs.
Protracted anaphylactic shock of guinea pigs led to death in over 90% of the animals, and good protection was obtained with an infusion of adrenaline after dibenamine pretreatment. Adrenaline alone, in doses which prevented the anaphylactic fall of arterial blood pressure, had no beneficial effect. Practolol abolished the therapeutic action of the combination of dibenamine/adrenaline. Stimulation of beta-receptors by isoproterenol did not increase the survival rate. With dopamine, however, a significant prolongation of the survival times was obtained.
