目的 :探讨胸外科术后并发肺炎的病原菌及其对抗生素的耐药性 ,指导临床合理使用抗生素。方法 :分析胸外科术后出现肺炎的 92例病人致病菌分类及抗生素治疗效果和耐药性。结果 :92例病人标本分离出 10 6株菌 ,菌株数居前 5位的依次排列为大肠杆菌、金葡菌、绿脓杆菌、克雷白肺炎杆菌、脆弱类杆菌。药敏试验 :目前临床上常用的抗生素对以上肺炎常见菌的耐药率达 35 %～ 95 %。结论 :抗生素的选择应以细菌培养结果为基础 ,未有细菌培养结果前应注意目前细菌耐药情况 ,同时避免滥用抗生素。
Objective: To investigate the pathogens of pneumonia after thoracic surgery and their antibiotic resistance, and to guide the rational use of antibiotics in clinic. Methods: The pathogenic bacteria of 92 patients with pneumonia after thoracic surgery were analyzed. The antibiotic treatment effect and drug resistance were also analyzed. Results: A total of 10 6 strains of bacteria were isolated from 92 patients. The top 5 strains of bacteria were sequenced as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae and Bacteroides fragilis. Drug susceptibility test: At present, commonly used antibiotics in clinical resistance to pneumonia more than 35% to 95% of the common bacteria. CONCLUSIONS: The selection of antibiotics should be based on the results of bacterial culture. Before the results of bacterial culture, bacterial resistance should be paid attention to, and antibiotics should not be abused.
