Shock, Pathology of Different Types, Animation


Shock also called circulatory shock is a
life-threatening clinical state characterized by body wide deficiency of
blood supply causing oxygen deprivation buildup of waste products and eventual
organ failure if untreated shock may have different causes and hence its
classification into different types hypovolemic or low volume shock happens
when the circulatory blood volume is severely reduced this can be caused by
external blood loss such as after an injury internal blood loss such as that
results from a ruptured blood vessel ruptured ectopic pregnancy pancreatitis
or fluid loss from major burns excessive vomiting diarrhea or urination
cardiogenic shock occurs when the heart fails to pump sufficiently this can
result from a sudden heart attack warned end stage development in various heart
conditions obstructive shock is caused by an
obstruction of blood flow in a major circulatory circuit distributive shock
results from excessive dilation of blood vessels or vasodilation which decreases
blood pressures distribution shock can have different causes the most common
being sepsis anaphylaxis and damage to the central nervous system in sepsis the
immune system is overwhelmed by an infection that gets out of control and
responds with a systemic cytokine release that causes vasodilation and
fluid leakage from capillaries in anaphylaxis the immune system over
reacts to an allergen releasing massive amounts of histamine which has similar
effects to cytokines peanut allergy is a common cause of anaphylaxis neurogenic
shock typically occurs as a result of a spinal cord injury as the autonomic
nervous system is damaged the sympathetic tone that normally keeps
blood vessels constricted is lost causing vasodilation and hypotension
common symptoms of shock include low blood pressures and signs of organ
damage such as confusion reduced urine output and cold sweaty modeled or bluish
skin although distributive shocks do to sepsis or anaphylaxis may initially
produce warm or flushed skin this is because the infection in sepsis usually
comes with fever and the allergic reaction in anaphylaxis is accompanied
by hives distributive shocks may also differ from other types of shock by
having at least initially normal or high cardiac output
as the body tries to compensate for hypotension fast heart rates and rapid
breathing may be observed diagnosis may also be assisted by blood tests for
blood lactate levels this is because in the absence of oxygen the body switches
to an alternative way of producing cellular energy called anaerobic
metabolism in which glucose is broken down only partially producing lactic
acid blood tests may also indicate signs of organ damage or infection in case of
sepsis shock is a medical emergency and requires immediate treatments which aim
to increase blood pressures and treat the underlying cause.
