Complications of disseminated intravascular coagulation in obstetrics

1. Shock

Acute DIC can lead to shock, and the degree of shock is out of proportion to the amount of bleeding. Because microthrombus blocks the pathway of microcirculation capillary network, tissue perfusion stops, and tissue cell necrosis can lead to shock. Microcirculation and systemic circulation shunt can also occur. Although microcirculation is blocked by blood clots, blood may return to veins without capillary short circuit, and the clinical manifestation may be normal arterial pressure. In fact, the perfusion rate of existing tissues and cells is insufficient, so although the degree of shock is different, if the perfusion rate of tissues and cells is not improved in time, the microcirculation is dredged, and different degrees of secondary fibrinolytic hemorrhage may eventually lead to serious circulatory disorder and irreversible shock. Therefore, DIC shock is not necessarily positively correlated with the amount of bleeding, and shock occurs rapidly, which is characterized by early shock and difficult recovery.

2. Organ embolism

Microthrombosis can involve one organ or more organs, and the symptoms of microthrombosis vary with the location and scope of blocked organs. Renal DIC is characterized by acute renal insufficiency, hematuria, oliguria or anuria. Cardiac DIC is characterized by acute cardiac insufficiency, arrhythmia and even cardiogenic shock. DIC in lung is characterized by dyspnea, pulmonary edema and pulmonary hemorrhage. DIC in brain can lead to delirium, convulsion and even coma, and adrenal DIC can lead to adrenal cortex necrosis and hemorrhage. Pituitary necrosis and bleeding can lead to Sheehan syndrome.
