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 .
Septic shock, especially septic shock where treatment is delayed or the antimicrobial drugs are ineffective, however has a mortality rate between 30% and 80%; cardiogenic shock has a mortality rate of up to 70% to 90%, though quick treatment with vasopressors and inotropic drugs, cardiac surgery, and the use of assistive devices can lower the ...
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.
In cardiogenic shock management, cardiotonic agents serve 2 functions. Norepinephrine , epinephrine , dopamine , and phenylephrine contribute mainly through their vasopressor (vasoconstrictive) functions to constrict blood vessels to correct hypotension.
Opening and keeping open the microcirculation is a consideration in the treatment of distributive shock, as a result limiting the use of vasopressors has been suggested. [2] Control of inflammation, vascular function and coagulation to correct pathological differences in blood flow and microvascular shunting has been pointed to as a potentially ...
Cardiogenic shock typically worsens with fluids. Providers should obtain an ECG and echocardiogram for patients suspected to have cardiogenic shock. Treatment can include vasopressors, inotropes, and treatment of any arrhythmias. [6]
In the initial treatment of low blood pressure in septic shock, the goal of vasopressor treatment is a mean arterial pressure (MAP) of 65 mm Hg. [10] In 2017, the FDA approved angiotensin II injection for intravenous infusion to increase blood pressure in adults with septic or other distributive shock. [18]
Treatment Hypoperfusion (Circulatory shock) Haemorrhagic shock: Hypovolemia (Hypovolemic shock) Intravascular volume status Heart rate (Tachycardia) / Systolic blood pressure (Hypotension) / Decreased urine output: Intravenous fluid / Intraosseous infusion / Blood transfusion with packed red blood cells: Cardiogenic shock: Cardiac output
