下呼吸道感染患者铜绿假单胞菌耐药性分析

目的了解医院下呼吸道感染患者铜绿假单胞菌耐药谱变化,指导抗菌药物合理使用。方法回顾性调查医院2005年6月-2006年12月下呼吸道感染患者痰标本培养情况,对分离的229株铜绿假单胞菌药敏试验结果进行统计分析。结果2005年6月-2006年12月共送检痰标本5411份,检出病原菌2291株(42.34%),分离铜绿假单胞菌229株(10.00%);铜绿假单胞菌对妥布霉素、亚胺培南、哌拉西林/他唑巴坦、阿米卡星、头孢他啶、头孢哌酮/舒巴坦、头孢吡肟敏感率均>60.00%;对复方新诺明的敏感率最低(1.31%)。结论治疗铜绿假单胞菌引起的下呼吸道感染,在结合药物敏感试验结果的同时应考虑该菌的耐药机制;同时应加强抗菌药物的管理,密切监测耐药谱变化,指导临床合理使用抗菌药物。

Resistance of Pseudomonas aeruginosa of Respiratory System Infection

OBJECTIVE To study resistance and the change of Pseudomonas aeruginosa of respiratory system infection,and instruct the antibacterial medicine to use rationally.METHODS The respiratory system infection patients from Jun 2004 to Dec 2005 were investigated.To the results of MICs with 229 P.aeruginasa strains were analyzed.RESULTS From inspected 5411 phlegm samples derived from Jun 2004 to Dec 2005,bacteria from 2291 samples(42.34%) were examined out,from them 229 strains(10.00%) were P.aeruginosa. The sensitive rate to tobramycin,imipenem/cilastatin sodium,piperacillin sodium,amikacin sulfate,ceftazidime,cefoperazone/sulbactam(Sulperazon),et al was greater than 60%.CONCLUSIONS We should consider the mechanism of P.aeruginosa resistance in treatment of respiratory system infection patients,and guide the management of antibacterial using.
