Studies on Blood Coagulation and Fibrinolysis in Pregnancy, during Delivery and in the Puerperium
Abstract
Blood coagulation and fibrinolytic variables were investigated with recently developed laboratory methods during normal pregnancy, at delivery and during puerperium. The state of hypercoagulability was registered by an increase in activity of factors XII, X and VIII, in VIII antigen, in ratio between VIII antigen and activity as well as in fibrinogen. Activation of blood coagulation at delivery results in decreasing levels of factors XII and XI and an increase in fibrinopeptide A. However, normal mean values of antithrombin and platelets were observed. An increase is noted in the plasminogen level as well as in urokinase inhibitor during pregnancy. In addition alpha 2-antiplasmin and prekallikrein were studied; however, no marked changes were noted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
