80岁以上老年患者的院内感染

A clinical study of nosocomial infection in patients over age of eighty

对１５４例８０岁以上老年患者的医院内感染进行回顾性调查，４１例发生院内感染５３例次，感染率为３４．４％（５３／１５４）。５３例次中，肺部感染占４７．２％，尿路感染占２０．８％，肠道感染占１３．２％，术后伤口感染占７．５％，其他（包括褥疮、胆道等感染）占１１．３％。细菌培养取得病原菌４２株，以革兰阴性杆菌为主，占７３．８％，革兰阳性球菌占１６．７％。这些病原菌对常用抗生素耐药情况严重。老年患者发生医院内感染与住院天数、损伤性医疗操作、机体免疫状态及滥用抗菌药物等因素有关。

Abstract A retrospective survey of hospital acquired infection in 41 of 154 elderly patients(age≥80 years) discharged from our hospital in a 12-month period from Jan. to Dec. 1992 was carried out. In the 53 times of nosocomial infections happened in the 41 cases, the incidence of nosocomial infection was 34.4% (53/154). Pulmonary infection accounted for 47.2%, urinary tract infection 20.8% and intestinal tract infection 13.2%. Seventythree point eight percen用名t of the organisms causing nosocomial infections were Gram-negative bacilli, 16.7% were Gram-positive cocci. The results of drug sensitivity test showed that strains resistant to commonly used antibiotics were very common. We found that the incidence of nosocomial infection in elderly was related closely to hospitalization days, improper medical manipulations, state of host immunity and abuse of antibiotics.
