气管插管是抢救呼吸衰竭病人的有效手段,但时常会合并机会菌感染.因此研究呼衰病人插管期间下呼吸道菌群分布及致病菌耐药性是防止感染加重,保证合理用药的有力措施.现将40例呼衰插管病人下呼吸道分泌物细菌培养结果报告如下.1 对象与方法 (1)对象:40例呼衰插管病人,男性25例,女性15例,年龄4～72岁.其中包括肺癌11例、心脏手术6例、脑外伤 Endotracheal intubation is an effective means to rescue patients with respiratory failure, but often merger opportunistic bacterial infections.To study the distribution of respiratory tract flora and pathogenic bacteria resistance during intubation in patients with respiratory failure is to prevent infection, to ensure the rational use of drugs 40 cases of respiratory failure patients with respiratory secretions bacterial culture results are reported as follows.1 Objects and Methods (1) Subjects: 40 cases of respiratory failure intubation patients, 25 males and 15 females, aged 4 to 72 Years old, including 11 cases of lung cancer, heart surgery in 6 cases, traumatic brain injury
