Platelet function, coagulation and fibrinolysis during termination of missed abortion and missed labor by PGF2 alpha and oxytocin.
In cases of missed abortion and missed labor, labor was induced by PGF2 alpha i.a., i.v. and by oxytocin infusion. Platelet function (methods of Born and Breddin), the coagulation system and fibrinolysis have been studied within the three groups. Using PGF 2 alpha i.v., the initially increased platelet aggregation showed a tendency to become normal. There was no manifestation of activation of the coagulation system. Fibrinolytic activity showed a slight increase during PGF2  alpha i.v. No essential changes in platelet function, coagulation and fibrinolytic system were found after i.a. injection of PGF2 alpha. When inducing labor by oxytocin i.v., both the coagulation and the fibrinolytic system were slightly activated and platelet aggregation increased. The results and their clinical importance for hemostasis as well as therapeutic consequences are discussed.
