Dobutamine is a medication used in the treatment of cardiogenic shock (as a result of inadequate tissue perfusion) and severe heart failure. [2] [3] It may also be used in certain types of cardiac stress tests. [2] It is given by IV only, as an injection into a vein or intraosseous as a continuous infusion. [2]
Cardiogenic shock is most commonly precipitated by a heart attack. [4] Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart attack, attempts to open the heart's arteries may help. Certain medications, such as dobutamine and milrinone, improve the ...
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
β 1 agonists stimulate adenylyl cyclase activity and opening of calcium channel (cardiac stimulants; used to treat cardiogenic shock, acute heart failure, bradyarrhythmias). Selected examples are: Denopamine; Dobutamine; Dopexamine (β 1 and β 2) Epinephrine (non-selective) Isoprenaline , isoproterenol (β 1 and β 2) Prenalterol; Xamoterol
Shock from blood loss occurs in about 1–2% of trauma cases. [34] Overall, up to one-third of people admitted to the intensive care unit (ICU) are in circulatory shock. [42] Of these, cardiogenic shock accounts for approximately 20%, hypovolemic about 20%, and septic shock about 60% of cases. [43]
The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine), which function as both neurotransmitters and hormones. Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other ...
Dobutamine [11] (in cardiogenic shock) is a beta-1 agonist that treats cardiac decompensation. Xamoterol [11] (cardiac stimulant) acts as a partial agonist that improves heart function in studies with cardiac failure. Xamoterol plays a role in modulating the sympathetic nervous system, but does not have any agonistic action on beta-2 adrenergic ...
A complication that may occur in the acute setting soon after a myocardial infarction or in the weeks following is cardiogenic shock. Cardiogenic shock is defined as a hemodynamic state in which the heart cannot produce enough of a cardiac output to supply an adequate amount of oxygenated blood to the tissues of the body. [14]
