摘要 目的探讨呼吸科病房铜绿假单胞菌对常用抗菌药物的敏感性。方法采用法国梅里埃公司ATB自动分析系统进行菌株鉴定及药物敏感性实验。结果分离出74株铜绿假单胞菌,其对药物敏感性依次为美洛培南94.6%,亚胺培南91.9%,奈替米星78.4%,阿米卡星75.7%,头孢哌酮-舒巴坦83.8%,哌拉西林-他唑巴坦81.1%,妥布霉素60.8%,头孢他啶63.5%,环丙沙星42.3%,头孢吡肟62.2%,庆大霉素39.8%,氨曲南73.0%,头孢曲松50.0%,头孢哌酮66.2%。与一年前同期相比,铜绿假单胞菌对环丙沙星的耐药率由原来的32.3%上升为54.5%,对哌拉西林-三唑巴坦则由原来的10.3%上升为26.1%,对妥布霉素的耐药性由原来的20.9%上升为24.3%。对其余抗菌药物耐药率无明显变化。结论铜绿假单胞菌对碳青酶烯类、氨基糖苷类依然保持较高的敏感性,对酰脲类青霉素及头孢哌酮-舒巴坦复合剂抗生素虽然有较高的敏感性,但耐药率有上升趋势。对环丙沙星及妥布霉素的敏感性与一年前相比有较明显下降。对铜绿假单胞菌的抗感染治疗仍可首选碳青霉烯类及头孢哌酮-舒巴坦。
