Abstract:
According to the hemodynamic changes,circulatory failure is divided into warm shock and cold shock,and severe circulatory failure often co-exist in both conditions in children.Circulatory failure in children is characterized by rapid change on hemodynamic status,pathologic vasodilation,relative or absolute hypovolemia,myocardial depression,altered blood flow distribution,and metabolic disorders.Therapeutic strategies include improving cardiac output and tissue perfusion,achieving SVO2＞70％ and cardiac index to 3.3～6.0 L/( min· m2 ),ensuring the intravascular blood volume and cardiac load.
