Abstract

The authors studied the effect of sodium salicylate administered into different parts of the circulatory system on various cardiovascular, respiratory and glottic parameters in Pentobarbital-anaesthetized rabbits. The results show that apnoea, bradycardia and hypotension, followed by hypertension, can also be caused by the extrathoracic action of salicylate. Cardiovascular responses induced by injecting salicylate into the carotid circulation are qualitatively the same, even after vagotomy, as in injection into the femoral vein. Salicylate injected into the common carotid artery, the internal carotid artery or the femoral vein causes inspiratory apnoea in rabbits, with powerful electrical activity of the diaphragm and an intrapleural pressure shift to marked inspiratory values. Laryngoconstriction occurs simultaneously, despite inspiratory apnoea. The injection of salicylate into the common carotid artery after bilateral vagotomy induces expiratory (not inspiratory) apnoea, indicating that the vagi play an important role in the origination of inspiratory apnoea in rabbits.
