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.
In severe sepsis and septic shock, broad-spectrum antibiotics (usually two, a β-lactam antibiotic with broad coverage, or broad-spectrum carbapenem combined with fluoroquinolones, macrolides, or aminoglycosides) are recommended. The choice of antibiotics is important in determining the survival of the person.
[3] [12] [13] Besides, nearly all kinds of distributive shock such as septic shock, neurogenic shock, anaphylactic shock, drug and toxin-induced shock, endocrine shock can turn out into refractory vasodilatory shock when the original shock becomes more severe. [14] [2] [15] [16] [17] [4] The most common cause of vasodilatory shock is sepsis. [5]
Distributive shock is different from the other three categories of shock in that it occurs even though the output of the heart is at or above a normal level. [2] The most common cause is sepsis leading to a type of distributive shock called septic shock, a condition that can be fatal. [1]
Septic treatment protocol and diagnostic tools have been created due to the potentially severe outcome septic shock. For example, the SIRS criteria were created as mentioned above to be extremely sensitive in suggesting which patients may have sepsis.

Bacteremia can have several important health consequences. Immune responses to the bacteria can cause sepsis and septic shock, which, particularly if severe sepsis and then septic shock occurs, have high mortality rates, especially if not treated quickly (though, if treated early, currently mild sepsis can usually be dealt with successfully). [6]
Mortality associated with severe sepsis remains high at 30-50%. When shock is present, mortality is reported to be even higher at around 50-60%. Approximately 1400 people die from sepsis each day throughout the world. In the U.S. there are approximately 750,000 new sepsis cases each year, with at least 210,000 fatalities and this is reported to ...
