Shock, secondary

Secondary shock is often associated with heat stroke, crushing injuries, heart attack (myocardial infarction), poisoning, fulminating infections, burns, and other life-threatening conditions. The pathologic characteristics of this state reflect changes in the capillaries, which become dilated and engorged with blood. This may develop over time and is characterized by weakness, restlessness, low body temperature, low blood pressure, cold sweat, reduced urinary output and progressive decrease in blood pressure that may lead to death unless appropriate treatment is provided.
