title: Changes in blood coagulation and fibrinolysis in the normal puerperium.
abstract: Blood coagulation and fibrinolysis variables have been studied in the normal puerperium in order to facilitate the decision to discontinue thrombosis prophylaxis after delivery. 16 women were followed longitudinally from the 1st to the 6th week post partum. Factor VIII activity and related antigen, fibrinogen, fibrinopeptide A, antithrombin III, plasminogen, tissue plasminogen activator (t-PA), fast inhibitor of t-PA, alpha 2-antiplasmin, urokinase inhibitors, fragment B beta 15-42 and kallikrein inhibition were analyzed. Both blood coagulation and fibrinolysis were significantly increased during the first 2 weeks, although simultaneously increased inhibitor capacity of both systems was present. 3 weeks post partum, blood coagulation and fibrinolysis were generally normalized, although the inhibitors remained raised compared to nonpregnant controls throughout the observation period.
