Fixed Volume or Fixed Pressure: A Murine Model of Hemorrhagic Shock
Published on: June 6, 2011
Abstract:
Recent advances with receptor-selective agonists and antagonists have provided great impetus to the deployment of drugs as experimental tools in cardiovascular research. Often overlooked, however, is the important limitation that few exogenous chemicals actually exert only one biologic action. This discussion appraised several prototype drugs used in this field, and theorized how a lack of consideration of subsidiary pharmacologic actions may lead to over-simplified interpretations of drug-based data.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...
