虽然采用提高免疫力的方法可以预防病房内的感染,但若能对病房内部发生感染的流行病学进一步剖析明确,并充分利用现有的控制传染的知识的话,则将更有裨益。考虑到:1.大多数在病房感染的病人并无显著的免疫抑制,但往往手术或创伤后仍发生急性的、可逆的、多器官的衰竭;2.大多数病房内感染是由需氧菌所致; 3.多数免疫功能正常而发生病房感染的病人常与外科手术、导尿、气管插管、输液治疗有关。如注意无菌技术,可减少感染。 Although immunization can prevent infections in the wards, further analysis of the epidemiology of infections in the wards and greater use of existing knowledge of infection control would be more beneficial. Considering: 1. Most patients infected in the wards have no significant immunosuppression but often undergo acute, reversible, multiple organ failure after surgery or trauma; 2. Most ward infections consist of aerobic bacteria ; 3. The majority of patients with normal immune function and ward infections are often associated with surgery, catheterization, endotracheal intubation, and infusion therapy. If attention to aseptic technique can reduce infection.
