１１８ 例支气管扩张合并感染患者的病原学及药敏分析

目的：分析118例支气管扩张合并感染住院患者的病原学及药敏情况，以指导临床抗菌药物的应用。方法对因支气管扩张合并感染需要住院的118例患者的痰培养和药敏结果进行回顾分析。结果118例痰培养68例阳性，阳性率为57．6％，其中革兰阴性菌66株，占97．0％，最常见的病原菌为铜绿假单孢菌，对第三、四代头孢菌素、氟喹诺酮类、氨基糖甙类、碳青霉烯类抗菌药物敏感。结论支气管扩张患者病原菌分布以革兰阴性杆菌为主，尤其铜绿假单孢菌感染。在药敏结果未报告前，可经验选择第三、四代头孢菌素、碳青霉烯类、氟喹诺酮类或氨基糖甙类抗菌药物。

Analysis of etiology and antibiotic susceptibility in infection complicated in bronchiectasis

Objective To investigate the etiology and antibiotic susceptibility in patients with bronchiectasis complicated by severe infection treated in Fuyang No. 2 hospital in 2013 to indicate the use of antibiotics. Methods Data of sputum culture and antibiotic suscepti-bility of 118 patients with boron complicated by severe infection were retrospectively analyzed. Results Positive sputum culture was obtained in 68 patients with the positive rate of 57. 6%. There were 66 stains of gram negative bacteria(97. 0%). Pseudomonas aeruginosa were the most common pathogens and had high sensitivity with cefozolin of III,IV,quinolones,aminoglycosides,carbopenems. Conclusion Gram-negative bacteria,especially pseudomonas aeruginosa are the main pathogens found in bronchiectasis patients. Before the report of suscepti-bility results,the cefozolin of III,IV,quinolones,aminoglycosides,carbopenems are experiential options.
