老年病人医院感染因素及耐药性分析

目的了解我院老年病人医院感染的各种危险因素，以及病原菌分布和耐药情况。方法用ATB鉴定细菌并作体外药教试验，统计、分析老年病人医院感染病原菌种类和药敏结果，以及与各种感染危险因素的关系。结果老年病人医院感染的发病率较高，尤以呼吸道感染多见。病原菌分布以铜绿假单孢菌和嗜麦芽窄食单胞菌等非发酵菌多见。感染因素主要为多脏器功能衰竭、深静脉插管等介入诊疗、激素等免疫抑制荆的应用和长期卧床等。结论老年病人因抵抗力低，易惠医院感染，且感染因素复杂.

The analysis of hospital infection factors and drug resistance in old patients

Objective To understand the infaetious factors of nosocomial infections for old patients. Methods The bacteria were identified by ATB, and the suscptlbility tests were also done by ATB, then the infectious factors were analyzed. Results The incidence of nosoeomiaJ in- fection was high, and the respiratory, tract infection was the most common infection. The most common bacteria were nonfermenters, especially P. aeruginosa, A. baumaunnli and S. mahophiiia. The most common infecious factor was the funetiunal exhaustion of many viscera. Conclu-sions The old patients were easy to get the no~comial inteetion because of the low immunity. The infecious iactors were complex.
