The treatment of infectious shock is based on fluid resuscitation, vasoactive drugs, antibacterial and antiviral drugs, removal of lesions and organs, and supportive therapy. Early and correct treatment can significantly reduce the morbidity and mortality of patients, refer to the following: a. Anti-infective treatment, within one hour of the diagnosis of infectious shock, intermittent antibiotic therapy, as much as possible for covering all aspects of bacteria and fungi. Before giving antibiotics, bacterial cultures should be retained, and if necessary, surgical removal of infected lesions. Second, anti-shock treatment, including circulatory function support, is recommended with crystalloid resuscitation, with two liters of intravenous input over three hours. Resuscitation goals are central venous pressure of 8-12 mmHg, mean arterial pressure ≥ 65 mmHg, urine output of approximately 30 ml per hour, central venous oxygen saturation ≥ 0.7, blood lactate decrease, and respiratory function support. Third, symptomatic supportive treatment: administer oxygen by nasal cannula or face mask, also can give non-invasive ventilator-assisted breathing, tracheal intubation, ventilator-assisted breathing, and renal system functional support if necessary. Under the premise of adequate volume resuscitation, the patient still has increased urine output, and if the internal environment is unstable, the doctor will give early renal function support, nutritional support, etc.
