Toxic shock syndrome is caused by toxins produced by certain bacteria, which can rapidly affect several organs including the liver, lungs and kidneys or cause severe conditions such as seizures, bleeding and heart failure.

Prolonged shock leads to multiple organ failure syndrome, which can cause rapid death. Therefore, shock patients need to be diagnosed early, managed and treated as soon as possible.

Traumatic shock needs to be recognized for timely and appropriate treatment, because traumatic shock can cause respiratory and circulatory failure quickly and endanger the patient's life.

Multiple organ failure syndrome is defined as altered organ function in critically ill patients and homeostasis cannot compensate. This condition is often life-threatening, affects in-hospital prognosis, and requires comprehensive care in the intensive care unit, especially rapid correction of shock of any cause.
