This article is about the pathological condition. For other uses of the term Shock, please see Shock (disambiguation).

In physiology and medicine, shock is "a pathological condition manifested by failure to perfuse or oxygenate vital organs."[1]



The physical examination, by estimating skin temperature and central venous pressure (>7 cmH2O), can frequently distinguish the type of shock that a patient has.[2]


Intravenous infusion of fluids

For more information, see: Intravenous infusion.

Solutions lower in chlorides such as Hartmann's solution and Lactated Ringer's solution, may cause less acute kidney injury when administered to adults in intensive care.[3] Likewise hydroxyethyl Starch should be avoided.[4]


Regarding medications for treating shock, "there is not sufficient evidence of any difference between any of the six vasopressors" according to a meta-analysis by the Cochrane Collaboration. [5]
