Disseminated intravascular coagulation symptoms in obstetrics

1. Bleeding

Uterine bleeding is the most common DIC in obstetrics, and it is often mistaken for postpartum hemorrhage with poor uterine contraction, which delays the rescue time. Uterine bleeding is characterized by continuous vaginal bleeding, varying amounts of bleeding and no blood clots. Severe may be accompanied by skin bleeding spots, gingival bleeding, hemoptysis, hematemesis, hematuria, and injection needle eye and surgical incision bleeding and bleeding.

2. Circulatory disorders

Due to microcirculation thrombosis, venous reflux decreases sharply, and blood loss leads to circulation disorder, blood pressure drop and shock. The destruction of a large number of platelets and the release of histamine and 5-tryptamine make microvasoconstriction, aggravate hypoxia, and seriously affect the functions of heart, liver, kidney and adrenal gland of main organs; Myocardial contraction was inhibited and cardiac function decreased. Because of renal cortical vascular embolism, ischemia and hypoxia, kidney necrosis can occur and lead to acute renal failure; Respiratory distress syndrome (ARDS) occurs in the lungs due to extensive embolism and bleeding of pulmonary capillaries, so symptoms such as confusion, weakness of pulse speed, dyspnea, cyanosis, oliguria or anuria may occur.

3. Mode of onset

Generally, the onset is fast, sudden and develops rapidly, with amniotic fluid embolism, early placental stripping and severe pregnancy-induced hypertension. Because of slow consumption of coagulation factors, the disease develops slowly and bleeding is mild, such as expired abortion and stillbirth.
