摘要
目的 :了解气管切开术后下呼吸道感染的病原菌分布及药敏情况。方法 :对 10 5例气管切开术后下呼吸道感染患者进行气管内分泌物细菌培养分离 ,并对分离出的细菌进行药敏试验。结果 :10 5例标本分离出致病菌 81例 ,阳性率 77.1% ;共检出细菌 10 9株 ,以革兰氏阴性杆菌为主 (71.5 % ) ;两种或两种以上细菌混合感染 2 3例 (2 8.4 % ) ;主要菌种为铜绿假单胞菌、大肠埃希氏菌和金黄色葡萄球菌。病原菌对常用抗生素有不同程度的耐药性 ,头孢他啶、亚胺培南、环丙沙星、丁胺卡那和万古霉素耐药率较低。结论 :气管切开术后下呼吸道感染以革兰氏阴性菌为主 ,混合感染多见 ,耐药严重 。
Objective: To investigate the pathogen of patient with low respiratory tract infection after tracheotomy. Method: Bacterial culture of secretion from 105 cases of patient with low respiratory tract infection after tracheotomy were performed and drug sensitivity was tested among positive cases. Result: 81 cases were positive(77.1%) and 109 strains bacteria were obtained, Among the isolates, most of them(71.5%) were gram-negative bacilli, 23 cases (28.4%) were infected by two or more kings of bacteria. The main pathogens were Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus. All the isolates were resistant more or less to the commonly used antibiotics. Conclusion: Low respiratory tract infection by gram-negative bacilli in patients after tracheotomy was commonly seen and drug resistance rate of microbe was very high. So drug sensitivity test should be done more often and antibiotics must be selected according to the test.
