Surgical infections are mainly complicated by trauma or surgery or burns, and their onset is relatively acute, usually accompanied by fever, and are divided into acute, subacute and chronic infections. Acute infections are usually seen in acute purulent peritonitis or abscesses formed by soft tissue infections, where the patient has a significant fever and even chills, as well as significant blood abnormalities. In the case of superficial abscesses, local fluctuations will be observed on examination, and surgical incision and drainage should be chosen promptly. Patients with deep infection mainly have obvious chills and abnormally high blood count, so they should also actively cooperate with the pathological examination and with surgical incision and drainage. It is common to see liver abscesses, and in severe cases, infectious shock, which affects the circulatory dynamics and can lead to death. Another is atopic infections, including tuberculosis or tetanus.
