Shock is an acute illness, rapid development, changes, serious endanger the lives of patients with acute illness. Shock by more serious poisoning, bleeding, trauma, heart disease, allergic reactions caused. Acute circulatory failure occurs in shock, the effective circulation of blood volume decreased dramatically, back to the amount of blood and cardiac output decreased, systemic microcirculation dysfunction, leading to severe ischemia of all important organs, hypoxia, and hypoxia caused by metabolic Obstacles and pathological changes. Shock when the body can not maintain the relative stability of the internal environment and the normal physiological function, resulting in a series of functional failure syndrome. Nurses should be prompt and accurate in preventing, detecting, treating and nursing shock. According to the cause of the disease, the cause of shock is divided into: First, infected with toxic shock caused by bacterial infection and more.
