血细菌培养阳性医院感染患者94例临床分析

目的探。方法对我院2004年7月至2005年12月血细菌讨细菌感染患者血液中培养出病原菌的分布及其耐药等情况，以指导临床合理使用抗生素培养阳性94例医院感染患者进行回顾性分析，调查其病原菌及药敏情况，并进行统计。结果94例中共检出病原菌103株，包括革兰氏阳性菌64株（62．14％），革兰氏阴性菌36株（34．95），以肺炎克雷伯菌、大肠埃氏菌、铜绿假单胞菌多见，真菌3株（2．91％）。结论近年来在我院临床败血症中分离到的病原菌，革兰氏阳性菌构成比比较高，细菌耐药情况日益严重，应注意掌握抗菌素的应用指征。

Analysis of the distribution of pathogen and drug-resistance in 94 cases with septicemia

Objective To study the distribution of pathogen and change of the drug-resistance,and the ratioal use of clinical antibiotics in patients with septicemia. Methods This retrospective study included 94 patients with septicemia proved by blood culture between July 2004 and December 2005. We investigated the distribution of pathogenic bacteria and analysised the drug-resistance,made a statistics. Results There were 103 strains of microorganisms isolated from 94 septic patients, including Gram-positive bacteria （ 62.14% ） , and Gram-negative bacteria（34. 95% ）. There were 3 cases of fungus septicemia. Conclusion In last 18 months, The isolated strains were seriously resistant to antibiotics. It＇s necessary to control the antibiotics abuse.
