Shock is a state of reduced tissue perfusion that results in cellular hypoxia. The definition of shock is a syndrome initiated by acute systemic hypoperfusion, leading to tissue hypoxia and vital organ dysfunction .
Shock is a systemic disorder affecting multiple organ systems.
The perfusion may be decreased either universally or there may be mal distribution as in septic shock. Because the perfusion is inadequate to meet the metabolic demands of the tissues, cellular hypoxia and an organ damage ensues. Management of shock during pregnancy differs in two important respects from it s management in other adults. First, normal physiologic changes occurred during pregnancy in most body organ systems. Second, during the antepartum and intrapartum stages of pregnancy, the clinician manages two patients, the mother and the fetus.
