目的分析支气管扩张(以下简称支扩)病原学、药敏与病程的关系,指导临床治疗。方法132例支气管扩张病人入院后第1～3天连续痰培养。结果病程少于10年,病原学以G+菌主;10年～20年G+菌和G-菌大致均等;大于20年以G-菌为主。结论支气管扩张患者随着病程延长,病原学逐渐由G+菌向G-菌转变,且最后以铜绿假单孢菌感染为主。
Objective To analyze the relationship between bronchiectasis (hereinafter referred to as branch expansion) etiology, drug sensitivity and duration of disease, and to guide clinical treatment. Methods 132 cases of bronchiectasis patients were admitted to the hospital after the 1st to 3 days of continuous sputum culture. Results The course of disease was less than 10 years. The pathogen was mainly G +, while G + and G-bacteria were roughly equal from 10 to 20 years. Conclusions As the course of disease prolongs in patients with bronchiectasis, the etiology gradually changes from G + bacteria to G- bacteria, and finally Pseudomonas aeruginosa infection.
