Infectious shock and toxic shock belong to two categories of shock with different mechanisms. Infectious shock usually refers to the widespread infection caused by gram-positive cocci or gram-negative bacilli, or other atypical pathogens, such as mycoplasma or chlamydia, when they invade the human body, which leads to a series of symptoms such as elevated temperature, rapid pulse rate, decreased blood pressure, pallor, oliguria or anuria, and pale or cold extremities, etc., or leads to insufficient perfusion flow to multiple organs and multiple organ failure. A series of symptoms, such as insufficient perfusion flow to multiple organs or multiple organ failure, is called infectious shock. For toxic shock, it usually refers to various factors that lead to acute or chronic poisoning, such as drug poisoning, food poisoning, bad gas poisoning, which leads to multiple organ failure, so the patient will go into shock. Infectious shock and toxic shock in the late stage of shock when the patient’s clinical symptoms are basically the same, but the mechanism of action is completely different.
