2024年11月8日 · Vasoactive agents include the following: inotropes are agents that increase myocardial contractility (inotropy) — e.g. adrenaline, dobutamine, isoprenaline, ephedrine; vasopressors are agents that cause vasoconstriction leading to increased systemic and/or pulmonary vascular resistance (SVR, PVR)

2024年12月11日 · Vasopressors and inotropes are medications that induce vasoconstriction or increase cardiac contractility, respectively, in patients with shock or severe hypotension. The hallmark of shock is reduced perfusion to vital organs, resulting in multiorgan dysfunction and eventually death.

Vasopressors are medicines that constrict (narrow) blood vessels, increasing blood pressure. They are used in the treatment of extremely low blood pressure, especially in critically ill patients.

2024年11月21日 · Vasopressors are a powerful class of drugs that induce vasoconstriction and thereby elevate mean arterial pressure (MAP). Vasopressors differ from inotropes, which increase cardiac contractility; however, many drugs have both vasopressor and inotropic effects.

This review article will provide background on the different types of shock, compare and contrast the commonly used vasoactive substances in critically ill patients, discuss titration strategies for these agents, and review management of extravasation of these agents.

2022年6月10日 · Vasopressors are powerful drugs that work quickly to narrow your blood vessels and raise your blood pressure. Vasopressor drugs can save your life by helping your organs to keep functioning.

Summarize the basic principles of volume resuscitation. Explain the rationale for the use of specific Vasopressors. What Goes Into Blood Pressure? Why Does it Matter? β-1 vs β-2 vs....β-3? Stimulation will increase CO, HR, and blood pressure, ↑ UO? What is Shock? What is Preload? OK, So Which Fluid? What’s Normal About Normal Saline?

Critically ill patients with hemodynamic instability refractory to intravenous fluids typically require vaso-active medications. Among these, vasopressors are used to improve SVR and blood pressure. Examples of vaso-pressors include phenylephrine, norepinephrine, epi-nephrine, dopamine, and vasopressin.

2022年11月20日 · Vasoactive medications often work as agonists or antagonists of adrenergic or parasympathetic receptors. These selected receptors represent the principal targets for vasoactive therapy in the intensive care setting ( Table 12.2 ).
