【摘要】 我院1986年8～10月院内感染率为9.06％,院内感染高危区为泌尿外科、血液病科、神经内科、神经外科、儿科。住院病人发生院内感染时的住院天数P₉₅=3.5天。院内感染病原体以绿脓杆菌多见,其耐药情况较社会感染病原体严重。住院病人抵抗力降低或具有感染倾向及各种诊疗操作手段等是院内感染的危险因素。更多还原

【Abstract】 In this survey, our hospital nosocomial infection rate of a 2-month period was 9.06%. The rates of Grade I and II nosocomial infection were 6.87% and 2.19% respectively. The hazard zones of nosocomial infection were services of urology(26.5%), hemotology (25.0%), neurology(21.4%), neurosurgery(17. 0%), and pediatrics(15.7%). The frequent sites of infection were lower respiratory tract(2.13%) and urinary tract(1.90%). The infections that develop 3.5 days after the admission of the patients were considered to be nosocomial infections (incubation period). The frequent pathogen of nosocomial infection was Ps. aeruginosa, and the freqent pathogen of community acquired infection was S. aureus. The difference of rate of antibiotic sensitivity between pathogens of the nosocomial infection (64.,9%) and community-acquired infect ion(70.0%) was highly significant statistically(P<0.01). The lowering of body resistance or the tendency toward infections of in-patients and various manipulations in the course of diagnosis and treatment of in-patients were the dangerous factors of nosocomial infection.更多还原
