The patient, a 48-year-old woman, was in cardiogenic shock and unresponsive to traditional therapy. An IABP was inserted by a cut down on the left femoral artery. Pumping was performed for approximately 6 hours. Shock reversed and the patient was discharged. [citation needed]
The Impella Device is a generational extension of the Intra aortic balloon pump (IABP) in addressing cardiogenic shock. Tech has allowed a single moving piece floated by magnetically steered mechanisms to deploy an "Archimedes Pump" just north of the Aortic Valve that purports to reduce both preload and afterload.
Cardiogenic shock is a medical emergency resulting from inadequate blood flow to the body's organs due to the dysfunction of the heart. Signs of inadequate blood flow include low urine production (<30 mL/hour), cool arms and legs, and decreased level of consciousness.
Because coronary flow is determined partly by coronary perfusion pressure, a reduction in CPP increases the risk of T2MI. Reduced CPP can be the result of a multitude of pathologies including cardiogenic shock and tachyarrythmia.
Cardiogenic shock leads to many harmful physiological effects. Specifically, in patients experiencing inadequate blood perfusion (with blood pressure below 80 mmHg), the American Heart Association / American College of Cardiology (ACC/AHA), recommends the use of Dobutamine and Milrinone. [75]
Low blood pressure and tachycardia are often seen in shock. Other symptoms depend on the underlying cause. [4] The physiology of obstructive shock is similar to cardiogenic shock. In both types, the heart's output of blood (cardiac output) is decreased. This causes a back-up of blood into the veins entering the right atrium. [3]
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 .
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]
