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 .
Vasoplegic syndrome or vasoplegia syndrome (VPS) is a postperfusion syndrome characterized by low systemic vascular resistance and a high cardiac output. Causes [ edit ]
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 ...
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system. Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1] This may be followed by confusion, unconsciousness, or cardiac arrest, as complications worsen. [1]
Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
Toxic shock syndrome; Tracheobronchomegaly; Transurethral resection of the prostate syndrome; Transverse myelitis; Treacher Collins syndrome; Trench foot; Tricho-hepato-enteric syndrome; Trichothiodystrophy; Tricho–dento–osseous syndrome; Tricho–rhino–phalangeal syndrome; Trigeminal trophic syndrome; Triple X syndrome; Triploid syndrome ...
It has also been used in septic shock and anaphylaxis. [34] [35] Methylene blue consistently increases blood pressure in people with vasoplegic syndrome (redistributive shock), but has not been shown to improve delivery of oxygen to tissues or to decrease mortality. [36] [37] [38] [39]
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1] [2] It can be caused by severe dehydration or blood loss. [3] [2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ ...
