THBD and Thrombocytopenia: All indicators before delivery were normal, but postpartum hemorrhage occurred after delivery.<h4>Diagnoses</h4>We retrospectively analyzed 1 neonate with pulmonary hemorrhage accompanied by thrombocytopenia and 1 pregnant patient with amniotic fluid embolism.<h4>Interventions</h4>The new coagulation indicators, such as thrombin-antithrombin complex, plasmin-alpha 2 antiplasmin complex, thrombomodulin, and tissue plasminogen activator-plasminogen activator inhibitor-1 complex, have been indicated to be valuable.
