当前防止医院内感染的重要性日益突出,医院内许多病人体质衰弱、免疫缺损或抑制,且目前应用免疫抑制剂和细胞毒性药物治疗的病人越来越多,这些病人极易感染和死亡,加上病原体耐药性普遍,以及携带抗菌素耐药性R-因子的细菌的病人出院后,可把这种R-因子带到家庭、社会上引起广泛传播,这些均增加了医院内感染问题的严重性。院内感染常见的病种: 由于医院类型和条件不同,院内感染率和易发生的病种亦可不同。常见有金黄色葡萄球菌(金葡菌)、假单胞菌(主要是绿脓杆菌)、链球菌、沙门氏菌或致病性大肠杆菌等感 The current importance of preventing nosocomial infections has become increasingly prominent. Many patients in the hospital are debilitated, immunodeficient or inhibited, and there are an increasing number of patients currently treated with immunosuppressive agents and cytotoxic drugs. These patients are extremely vulnerable to infection and death Pathogens are generally drug-resistant and bacteria that carry antibiotic-resistant R-factors are released from the hospital to bring this R-factor into the home and to cause widespread epidemics in the community, all of which add to the serious problem of nosocomial infections Sex. Nosocomial infections common diseases: Due to the different types of hospitals and conditions, the hospital infection rate and prone to disease may also be different. Common with Staphylococcus aureus (Staphylococcus aureus), Pseudomonas (mainly Pseudomonas aeruginosa), Streptococcus, Salmonella or pathogenic Escherichia coli and so on
