Treatment typically involves uses of vasopressor, inotropes, fluid boluses, and introduction of resuscitation. [4] In case vasodilatory shock fails to respond to high doses of vasopressors (defined as ≥ 0.5 mg/kg/min norepinephrine-equivalent dose [ 7 ] ), meaning it's vasopressor-resistant and advances to being called refractory vasodilatory ...
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 ...
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 ...
Very long-chain acyl-coenzyme A dehydrogenase deficiency is a fatty-acid metabolism disorder which prevents the body from converting certain fats to energy, particularly during periods without food. [1] [2] [3] Those affected by this disorder have inadequate levels of an enzyme that breaks down a group of fats called very long-chain fatty acids.
The mechanism that leads to vasoconstriction results from the increased concentration of calcium (Ca 2+ ions) within vascular smooth muscle cells. [2] However, the specific mechanisms for generating an increased intracellular concentration of calcium depends on the vasoconstrictor.
Diagnosis is often delayed since most of the symptoms of adrenal insufficiency are nonspecific and develop insidiously. [5] Hypotension and shock that fail to respond to vasopressors or fluid resuscitation are the main signs of an adrenal crisis. [6] Those in an adrenal crisis can deteriorate quickly, usually within a few hours. [7]
Delaying initiation of vasopressor therapy during septic shock is associated with increased mortality. [73] Norepinephrine is often used as a first-line treatment for hypotensive septic shock because evidence shows that there is a relative deficiency of vasopressin when shock continues for 24 to 48 hours. [74]
Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia.
