Sepsis causes pathogens to invade the human circulation and multiply there to produce toxins. General treatment, symptomatic treatment and pathogenic treatment are usually adopted. 1. General treatment: strengthen nutrition, supplement sufficient vitamins; strengthen nursing care, pay attention to oral hygiene, prevention and treatment of candida stomatitis. Serious patients should turn over regularly to prevent secondary pneumonia and pressure sores. 2. Symptomatic treatment: give physical cooling and oral ibuprofen, acetaminophen and other antipyretic drugs when the body temperature is ≥38.5 ℃, keep the respiratory tract open with oxygen; supplement the necessary water, heat and electrolytes to maintain the water, electrolyte and acid-base balance as well as peripheral circulation and excretion of metabolic waste. Infusion also provides access to intravenous drug delivery. 3. Pathogenic treatment: once sepsis is suspected, antibiotic treatment must be carried out immediately. Commonly used drugs include penicillin, cephalosporins (ceftriaxone, ceftazidime, etc.), β-lactams (amitraz), carbapenems (meropenem), and so on. All of the above medications should be used under the supervision of a doctor and avoid self-medication. Hospitalization is recommended in cases of persistent fever, weak general condition, and prolonged delay of unknown cause.
