Sepsis is the production of toxins by bacteria in the blood, which causes an inflammatory response and damage to the whole body. Sepsis, on the other hand, is mainly a response of the body to infection after the infection has eroded, resulting in multi-organ dysfunction. So the difference is that sepsis includes relatively more elements, and sepsis is only a part of the physiological development of sepsis. Sepsis as well as septic shock is actually a big problem in critical care at present, with about 25% of septic patients having life-threatening and fatalities every year, and generally sepsis can be cured in a large proportion of patients after treatment in about 7-14 days. However, this depends on the patient’s condition, the condition of his own organism, immune function, including the erosion of bacterial resistance, sensitivity to antibiotics and related drugs, and then whether the treatment is timely and correct, all have relevance, so the specific time should be determined according to these relevance. It is recommended to go to the regular hospital for relevant examination and correct treatment in the early stage of sepsis.
