摘　　要：目的　了解外科重症监护病房 (SICU)中医院获得性感染 (nosocomialinfection ,NI)的流行病学规律 ,指导临床防治。方法　对SICU 1996年 1月至 2 0 0 0年 12月间 181例NI情况进行回顾性分析。结果　平均感染率 9 81% ,常见感染部位是呼吸道 (36 96 % )、胸腹腔 (2 5 47% )和血行感染 (9 32 % )。各部位主要病原菌种类具有统计学差异 ,呼吸道、胸腹腔和胆道以细菌为主 ,泌尿道和消化道以真菌为主 ,混合感染 5 2 2 5 %。常见病原菌是肠球菌、耐甲氧西林的葡萄球菌、铜绿假单胞菌、大肠埃希杆菌、白色念珠菌和热带念珠菌。结论　SICU内NI主要病原菌因感染部位而不同 ,菌种复杂 ,耐药菌株多 ,应建立相应的监控制度 ,掌握病原菌变化规律 。Objective\ To evaluate the prevalence of NI in the SICU at our hospital.Methods\ 181 NI patients in the SICU were retrospectively analysed during Jan 1996～Dec 2000.Results\ The average NI rate was 9.81%.The major sites of NI were respiratory tract(36.96%),thoracic/abdominal cavity(25.47%)and bloodstream infections(9.32%).The difference in major pathogens of infections in different sites reached statistical significance.For respiratory tract,thoracic/abdominal cavity and bloodstream infections,bacteria were the most common pathogens.Fungi were the most frequent isolate from urine and stool.Mixed infection proportion was 52.25%.The most common pathogens were Enterococci,Methicillin resistant Staphylococci、Pseudomonas Aecruginosa、Escherichia Coli、Candida Albicans and Candida Tropicalis.Conclusions\ The most common pathogens of NI in SICU are different in different infection sites.The pathogens were complicated and most strains are antibiotics resistant.So it is important to establish NI control and to understand the changes of pathogens so as to prevent the infection.
