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]
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
Some substances do both (e.g. dopamine, dobutamine). If low blood pressure is due to blood loss, then preparations increasing volume of blood circulation—plasma-substituting solutions such as colloid and crystalloid solutions (salt solutions) [ 1 ] —will raise the blood pressure without any direct vasopressor activity.
Hypotension during coronary reperfusion [5] Hypotension following injection of contrast media during coronary angiography [ 5 ] Exertional syncope in aortic stenosis: in severe aortic stenosis exercise may cause a rise in left ventricular pressure which stimulates the Bezold–Jarisch reflex and results in reflex vasodilation and syncope.
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. . Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocar
The concomitant presence of hypoxia and hypotension upon admission resulted in a 75% mortality. [20] Evidence strongly suggests that the avoidance or minimization of hypotension during the acute and postinjury period following traumatic brain injury had the highest likelihood of improving outcomes of any one single therapeutic maneuver.
