WebCatecholamine production is regulated systemically via humoral messengers generated by the hypothalamus-pituitary-adrenal (HPA) axis, and locally by neural components of the sympathetic division of the autonomic nervous system. WebAug 1, 2001 · Increased catecholamines at delivery contribute clearly to lung fluid reabsorption, surfactant release, and systemic hemodynamic adaptations (25, 34). However, the effects of such a catecholamine release surge at birth on the pulmonary circulation are not known. Conflicting results exist on the vascular effects of catecholamines.
WebJan 17, 2024 · The mechanism is probably by adrenergic receptor blockade and a consequent reduction in catecholamine-mediated release of pro-inflammatory cytokines by monocytes. Some of the reduction in all-cause mortality observed in patients treated with beta-blockers for cardiac conditions might be due to systemic anti-inflammatory effects.
WebA prolonged period of cardiac, vascular, and nerve terminal catecholamine depletion follows, associated with progressive reduction in systemic arterial pressure (explained by reduction in vascular resistance). Hypotension is less marked in the supine posture or with agents that simultaneously contract or prevent reexpansion of plasma volume.7,8
