Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
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 ...
Cold shock response is a series of neurogenic cardio-respiratory responses caused by ... Death which occurs in such scenarios is complex to investigate and there are ...
Neurogenic shock occurs due to spinal cord injury, which leads to inability to balance signals from the autonomic nervous system to maintain ideal blood pressure and other vital signs. [4] Blood flowing through vessels in the body follows Poiseuille's Law , meaning that the flow of fluid depends on a number of factors such as tube length, fluid ...
Septic shock (a form of distributive shock) is the most common form of shock. Shock from blood loss occurs in about 1–2% of trauma cases. [ 34 ] Overall, up to one-third of people admitted to the intensive care unit (ICU) are in circulatory shock. [ 42 ]
There are three main types: neurogenic, venous, and arterial. [1] The neurogenic type is the most common and presents with pain, weakness, paraesthesia, and occasionally loss of muscle at the base of the thumb. [1] [2] The venous type results in swelling, pain, and possibly a bluish coloration of the arm. [2]
In spinal cord injuries above T6, neurogenic shock may occur, from the loss of autonomic innervation from the brain. Parasympathetic is preserved but the synergy between sympathetic and parasympathetic system is lost in cervical and high thoracic SCI lesions.
Obstructive shock can occur in the setting of tension pneumothorax and cardiac tamponade. These etiologies should be uncovered in the primary survey. [3] In the setting of head or neck trauma, an inadequate sympathetic response, or neurogenic shock, is a type of distributive shock that is caused by a decrease in peripheral vascular resistance. [3]
