Abstract

Hemostasis represents a balance between pro- and anti-coagulant processes, with variations in this balance determining the net outcome. Significant physiological changes during pregnancy result in a hypercoagulable and hypofibrinolytic state that serves to protect the mother from bleeding complications at the time of placental separation. This chapter describes the effects of pregnancy on parameters of primary hemostasis, coagulation factors, anticoagulant pathways and the fibrinolytic system.
