Coagulation abnormalities •Hypofibrinogenemia •Increaseing levels of fibrin degradation products •decreasing platelet count •Increasing prothrombin time and partial thromboplastin time •Decreasing other serum clotting factors
Ultrasonography relatively large retroplacental clots may be detected Placental examination The extent of placental abruption of the maternal surface of the placenta on which a clot is detect at the time of delivery

Management Maintain hemodynamic stabilization Transfusion therapy o Crystalloid transfusion wHole blood therapy component therapy Correct coagulation status
Management Maintain hemodynamic stabilization ( Transfusion therapy) •Crystalloid transfusion •Whole blood therapy •Component therapy Correct coagulation status
Delivery .When the fetus is mature vaginal delivery is preferable unless there is evidence of fetal distress or hemodynamic instability. When the fetus is not mature and placental abruption is limited, observation with close monitoring of both fetal and maternal status
