[Comparative coagulation studies in induced therapeutic abortions with prostaglandin]

Therapeutic abortion in the first trimester of pregnancy have been done in ten primigravidae using PGF2 alpha, 15-methyl-PGF2 alpha, or Sulprostone. Bleeding and recalcification time, platelet count, fibrin, platelet adhesiveness, partial thromboplastin time and thromboplastin time were examined before, during and after treatment. We found a decrease of platelet count and a prolongation of bleeding and recalcification time. There was no intensive-influence on coagulation system by the prostaglandin used. Therefore prostaglandins may be used for therapeutic abortion.
