Systemic catecholamine release

WebOne of our goals was to study the direct bronchoprotective effects of these anesthetic agents and to eliminate any potential confounding effects that these agents might induce through circulating catecholamines systemically. We continuously measured the blood pressure and heart rate in each animal throughout the study. WebSep 1, 1990 · This release, which is independent of both central sympathetic activation and extracellular calcium, occurs in two steps. First, catecholamines escape from their storage vesicles and accumulate in the cytoplasm of the neuron.
