Shock is a descriptive term indicating generalized inadequancy of organ perfusion. In the critically ill patient, the common denominator is insufficient microcirculatory flow. All patients have excessive sympathetic tone with arteriolar and venular vasoconstriction. ⋯ Although the presentation of shock may vary with age, one usually detects evidence of inadequate tissue perfusion, hypotension, and poor urine output. Treatment consists of early recognition, establishment and maintenance of intravascular volume, and cardiorespiratory assistance with mechanical ventilation and various inotropic and vasoactive drugs. Pediatric mortality remains high despite new and sophisticated treatment methods.
