Shock is a medical emergency and requires urgent medical care. If shock is suspected, emergency help should be called immediately. While waiting for medical care, the individual should be, if safe, laid down (except in cases of suspected head or back injuries). The legs should be raised if possible, and the person should be kept warm.
Neurogenic shock can result from severe central nervous system damage (brain injury, cervical or high thoracic spinal cord). [1]In simple terms, the trauma causes a sudden loss of background SNS stimulation to the blood vessels.
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 ...
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.
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.
The term "spinal shock" was introduced more than 150 years ago in an attempt to distinguish arterial hypotension due to a hemorrhagic source from arterial hypotension due to loss of sympathetic tone resulting from spinal cord injury. Whytt, however, may have discussed the same phenomenon a century earlier, although no descriptive term was assigned.
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. [1] Obstruction can occur at the level of the great vessels or the heart itself. [ 2 ] Causes include pulmonary embolism , cardiac tamponade , and tension pneumothorax . [ 3 ]
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 ...
