手术部位感染包括手术切口及手术脏器感染,是常见的医院感染。造成手术部位感染的主要原因系手术技术自身所决定,因此外科手术必然破坏人体宿主抵抗力的第一道防线(皮肤和黏膜)屏障,易使细菌进入人体。鉴于临床上与手术部位感染相关的危险因素甚多,如何从临床实际工作中正确认识这些危险因素显得十分的重要。临床造成手术部位感染 Surgical site infections, including surgical incision and surgical organ infection, is a common nosocomial infection. The main cause of infection at the surgical site is determined by the surgical technique itself, so surgery is bound to undermine the first line of defense (skin and mucous membrane) barriers to human host resistance, allowing bacteria to enter the body. In view of the clinical risk factors associated with surgical site infection is very much, how to correctly understand these risk factors from clinical practice is very important.
