Dialysis helps to improve the renal failure that occurs when sepsis involves the kidneys, but sepsis cannot be cured by dialysis alone. The treatment of sepsis needs to be based on infection control, combined with symptomatic supportive therapy. Septicemia is generally a severe systemic reaction induced by the entry of certain pathogens, such as bacteria, into the human bloodstream. In severe cases, sepsis can induce one or more organs to fail, seriously threatening the patient’s life. When sepsis induces acute renal failure, dialysis can be used to maintain normal renal function and help patients get through the critical stage of the disease. However, dialysis is only a symptomatic treatment and cannot cure sepsis fundamentally. For sepsis, the first thing needed is targeted antimicrobial treatment, through blood culture and drug sensitivity test, give the patient intravenous injection of sensitive antibiotics for treatment, such as meropenem and so on. At the same time of anti-infective treatment, attention should be paid to the monitoring of patients’ vital signs and giving symptomatic supportive treatment. When the patient has insufficient perfusion or hypoxia, it is necessary to replenish body fluids to avoid shock and give oxygen; when the patient has cardiac dysfunction, it is necessary to give cardiac therapy. Cure sepsis, need to combine a variety of means of comprehensive treatment, specific treatment should follow the doctor’s instructions, the use of drugs should be under the guidance of the doctor.
