The cause of the death of a pregnant woman after middle -class hemorrhage, amniotic fluid embolism, pulmonary embolism, thrombosis, thrombocytopenia, puerperidal infection ranked in the top five. The detection of maternal coagulation function can effectively prevent the scientific basis of acute DIC and thrombosis disease caused by postpartum hemorrhage during childbirth during childbirth.

1. Postpartum bleeding
Postpartum hemorrhage is one of the main causes of complications of obstetrics at present and the main causes of death of pregnant women, and the incidence rate accounts for 2%-3%of the total number of childbirth. The main causes of postpartum hemorrhage are the fat contraction, placenta factors, soft laceration of laceration and coagulation dysfunction. Among them, bleeding caused by coagulation dysfunction is often a large amount of bleeding that is difficult to control. Essence PT, APTT, TT, and FIB are common screening experiments commonly used in plasma coagulation factor.

2. Thromic disease
Due to the special physiological characteristics of pregnant women, the blood is high -coordinated and the blood flow is slow. The number of older and high -risk pregnant women increases. The risk of pregnant women with thrombosis is 4 to 5 times that of non -pregnancy women. vein. The thrombosis disease is mainly deep vein thrombosis in the lower limbs. The mortality of pulmonary embolism caused by thrombosis is as high as 30%. It has greatly threatened the safety of pregnant women, so it is essential for early identification and treatment of venous thrombosis. Especially cesarean section of postpartum bleeding or infection, or patients with patients such as obesity, hypertension, autoimmune disease, heart disease, sickle cell disease, multi -pregnancy, pre -periodic periodic complications or obstetric complications The risk of intravenous thrombosis is greatly increased.
