300例死亡病人医院感染的回顾性调查

A Retrospective Survey on Nosocomial Infection in 300 Died Patients

本次调查结果表明:医院感染的发病率为29.7％。高危病区为血液病科、传染病科、胸外、矫外及胃肠外科。感染最多部位是下呼吸道(35.4％),其次为伤口感染(11.0％)。69.5％的病原菌是革兰氏阴性杆菌,其中78.1％为绿脓杆菌、产气杆菌和大肠杆菌。85株病原菌药敏结果显示耐药率为57.9％。本文对医院感染的危险因素及控制措施作了简要讨论。

This retrospective survey revealed that the incidence of nosocomial infection was 29.7 % among 300 died patients. The places with high risk for infection were wards of hemotologic disease, infectious diseases, thoracic surgery, orthopedic surgery and gastrointestinal surgery. The most frequently infected parts were lower respiratory tract (35.4%) and wounds infection (11.0%). 69.5% of the organisms responsible for nosocomial infection were Gram-negative bacilli, 78% of them being pseudomonas aeruginsa, enterobecter aerogenes and escherichia coli. Antibiotic sensitivity test performed on 85 bacteria strains showed that 57.9% of them were resistant to commonly used antibiotics. Dangerous factors and control measures of nosocomial infection were also discussed briefly.
