摘　　要：目的:通过研究高龄冠状动脉搭桥术患者手术后下呼吸道感染菌群分布及药物敏感性,为临床护理提供参考。方法:对2004年7月-2012年1月216例冠状动脉搭桥术患者合格痰标本进行培养、鉴定,观察菌株分布情况。用K2B纸片法进行常用抗生素的敏感性测试。结果:在216份痰标本中共培养出菌株177株,其中G+菌株34株,(19.2%),G-菌株143株,(80.8%)。G-菌株对10种常用抗生素敏感性测试结果表明,对三代头孢药物敏感性均在80.0%以上。结论:合理用药可以明显降低细菌耐药性发生。Objective： To investigate the bacteria causing lower respiratory tract infection and its drug sensitivity after coronery artery bypass grafting so as to provide a reference for clinical medication. Method： Specimens of sputum of patients undergoing coronery artery bypass grafting , from March 2004 to January 2010 , were cuftured , determined and the distribution was observed. The K2B paper method was used for common antibiotics sensitivity test. Result： The positive cultures were 177 strains in the 216 specimens , 34 strains of them were G- （ 19.2 % ） and 143 strains were G- （ 80.8 % ） . 10 commonly used antibiotics were tested for the sensitivity. The results of the test showed that the drug sensitivity was more than 80.0 %for the third generation cephalosporin. Conclusion： The resistance in bacteria can be reduced so long as judicious use of proper antibiotics.
