Summary of Types of Shock | Septic, Anaphylactic, & Neurogenic Shock

00:00:00 - 00:35:00

Shock is a dangerous medical condition caused by a decrease in blood pressure and volume. This can be caused by a variety of factors, including sepsis, thrombosis, and vasoconstriction. Shock can lead to ischemia, necrosis, and disseminated intravascular coagulation, among other complications. Treatment typically involves antibiotics and fluids, and may also include vasopressors.

• 00:00:00 Distributive shock is caused by a decreased tissue perfusion, typically due to a decrease in systemic vascular resistance. In septic shock, this decreased tissue perfusion is due to an increase in the number of inflammatory cells. The increased number of inflammatory cells and their release of inflammatory chemicals into the blood vessels leads to increased vascular permeability and fluid accumulation in the tissues. This accumulation of fluid and inflammatory cells can lead to organ failure.
• 00:05:00 Shock is a dangerous medical condition caused by a decrease in blood pressure and volume. Chemotactic agents, which are released by the body in response to shock, draw in white blood cells, which can then cause an increase in inflammation and the production of acute phase reactants.
• 00:10:00 Shock is a medical emergency caused by a decreased blood flow to the tissues. This can happen due to a variety of factors, including sepsis, thrombosis, and vasoconstriction. Shock can lead to ischemia, necrosis, and disseminated intravascular coagulation, among other complications.
• 00:15:00 Shock can be caused by a variety of reasons, some of which are due to an allergic reaction. Treatment typically involves antibiotics and fluids, and may also include vasopressors. If the underlying cause of the shock cannot be treated, a doctor may inject someone with a contrast agent to help see the injuries.
• 00:20:00 Shock can be caused by a number of different things, including exposure to an allergen. When this happens, the allergen will be processed by certain cells, leading to expression of the allergen on the cell's membrane with an MHC 2 complex. This allergen will then be taken to a T helper cell, where it will be expressed with a target cell receptor and other proteins. This will activate the mast cell, which will produce a number of chemical mediators. Some of these mediators will be harmful, leading to increased production of histamines.
• 00:25:00 Shock can be caused by a variety of factors, including histamines, vasodilation, and inadequate oxygen delivery to tissues. Epinephrine can help to constrict blood vessels and maintain blood pressure, and may be necessary in some cases to treat the patient.
• 00:30:00 Shock can be caused by a variety of factors, including septic, anaphylactic, and neurogenic shock. Antihistamines can help to block histamine receptors and prevent the symptoms of vasodilation, itching, redness, laryngeal edema, angioedema, and death. Neurogenic shock is caused by an injury to the nervous system, and can result in a decrease in heart rate and contractility, as well as a lack of vasoconstriction of blood vessels. Treatment typically includes giving patients basal pressors and fluids, as well as vasopressors and corticosteroids, if needed.
• 00:35:00 Shock can result in decreased blood flow to the tissues, which can lead to organ failure. Shock can be classified by the cause of the shock, such as septic, anaphylactic, or neurogenic.
