Changes of Coagulation and Fibrinolytic Status Detected by Thromboelastography (TEG6s®) in Pregnancy, Labor, Early Postpartum, Postpartum Hemorrhage and Heparin Treatment for Perinatal Venous Thrombosis

Changes of Coagulation and Fibrinolytic Status Detected by Thromboelastography (TEG6s®) in Pregnancy, Labor, Early Postpartum, Postpartum Hemorrhage and Heparin Treatment for Perinatal Venous Thrombosis

The aims of this study are to evaluate coagulation and fibrinolytic features using TEG6s® in normal pregnant courses, in the early postpartum period and in cases with postpartum hemorrhage (PPH) caused by uterine atony. We also analyze cases with deep venous thrombosis (DVT) and/or pulmonary embolis...

Description
Summary:The aims of this study are to evaluate coagulation and fibrinolytic features using TEG6s® in normal pregnant courses, in the early postpartum period and in cases with postpartum hemorrhage (PPH) caused by uterine atony. We also analyze cases with deep venous thrombosis (DVT) and/or pulmonary embolism (PE) under treatment with unfractionated heparin. The non-pregnant women (n = 13) and healthy pregnant women (at 9–13 weeks of gestation (n = 13), at 27–30 weeks of gestation (n = 14), at 35–38 weeks of gestation (n = 14)) were cross-sectionally studied, while the normal pregnant women at delivery (n = 14) were sequentially investigated. Blood samples from those patients with PPH (n = 15) and DVT and/or PE (n = 11) were also obtained and compared with those of normal women. Significant changes of clot formation parameters were observed in all parameters and, interestingly, fibrinolytic parameter (LY30) was maintained at a low value even within 120 min after placental delivery (median of LY30; 0) and also in cases with uterine atony (median of LY30; 0.1). The parameter that indicates the effectiveness of heparin showed strong correlation (R = 0.788) with activated partial thromboplastin time. Thromboelastography may be less sensitive to fibrinolysis in the conditions of uterine atonic bleeding.
