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.
Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1 ] [ 2 ] It is one of four categories of shock , a condition where there is not enough oxygen -carrying blood to meet the metabolic needs of the cells ...
Efficacy of vasopressin on systemic hemodynamics in catecholamine-resistant septic and postcardiotomy shock have been studied and published first in 2001 [8] Later, the group concluded the ischemic skin lesions (ISL) developed in patients with catecholamine-resistant vasodilatory shock have multi-factorial cause and shall not necessarily been ...
This is sometimes “sub” classified as obstructive shock, but you can see that the cause is still due to the heart’s inability to do its job, right? Similarly to hypovolemic shock, a reduction in cardiac output leads to lowered blood flow, so the skin gets cool and clammy and so cardiogenic shock is also considered a kind of cold shock.
Common signs of shock include weak pulses, altered mental status, bradycardia or tachycardia, low urine output, hypotension, and pale, cold skin. [6] Treating shock focuses on increasing blood flow and oxygen delivery to tissues and organs before organs are permanently damaged. [4] This section will discuss the recognition and management of shock.
