If an abdominal infection causes a person to die, it means that the infection has entered the bloodstream and diffused throughout the body, with complications such as sepsis or sepsis, at which point the probability of death increases as a result of systemic multi-organ and multifunctional failure. Infection itself is a major problem in surgical medicine, with various aseptic operations in surgery, various delicate tools and techniques to avoid infection, and abdominal infections are usually secondary to perforation or lesions of the abdominal organs. The abdominal cavity itself has more blood vessels and lymphatic vessels, and when a serious infection forms, it can easily enter the bloodstream and diffuse throughout the body with the blood. When systemic infection is present, especially after combined surgery, the patient’s underlying condition is poor, which is usually irreversible and difficult to treat, and with systemic or local infection, the patient’s surgical area or wound will not heal.
