DIC is diffuse intravascular coagulation, and the type of shock that is more likely to result in DIC is infectious shock. Infectious shock is more prone to DIC because the perfusion of microcirculation of various organs decreases in shock, blood flow slows down, bacteria and their metabolites, especially the common gram-negative bacilli, tend to cause vascular injury, and after the vascular injury, the muscle may activate the system of coagulation, which leads to the occurrence of intravascular disseminated coagulation. Infectious shock is mainly manifested as acute renal failure, acute pulmonary failure, acute cardiac insufficiency and so on. As there are some toxins, metabolites and other products in the body of patients with infectious shock, these substances are prone to invade the blood, activate the cells and tissues in the body, and produce an anti-inflammatory mediator. This mediator easily damages various organs and tissues in the body, leading to abnormal metabolism, anemia, hypoxia, and in severe cases, organ failure, therefore, such patients are more likely to develop DIC. If the symptoms of infectious shock occur, it is recommended to send to the doctor for treatment in time, and the patient needs to be treated with anti-shock therapy under the guidance of the physician, such as volume expansion therapy, correction of acidosis (sodium bicarbonate injection), and anti-infection. Specific diagnosis and treatment need to be carried out under the guidance of physicians.
