探讨依拉环素治疗多重耐药鲍曼不动杆菌引起肺部感染合并血流感染的疗效和安全性。
回顾性分析2024年2月至8月武汉亚心总医院重症医学科收治的3例因多重耐药鲍曼不动杆菌引起肺部感染合并血流感染患者的临床资料,包括生化指标、细菌培养及药敏试验结果、抗菌药物种类、治疗前后影像学资料,评估患者临床疗效、用药不良反应等。
3例患者均为男性,年龄38~58岁,分别在肺泡灌洗液、血液中检出鲍曼不动杆菌,药敏试验结果均提示对碳青霉烯类抗生素耐药。依拉环素治疗后患者临床表现、炎症指标及影像学检查均明显好转,且未发现依拉环素治疗相关不良反应。
依拉环素对多重耐药鲍曼不动杆菌引起肺部感染合并血流感染具有良好的疗效及安全性。

To investigate the efficacy and safety of Eravacycline in the treatment of pulmonary infection combined with bloodstream infection caused by multidrug-resistant Acinetobacter baumannii.
A retrospective analysis was conducted on the clinical data of three patients admitted to the ICU of Wuhan Asia Heart General Hospital from February to August 2024. These patients had pulmonary infection and bloodstream infection caused by multidrug-resistant Acinetobacter baumannii. Biochemical indexes, bacterial culture and antimicrobial susceptibility test results, antimicrobial regimens, imaging data before and after treatment were collected to evaluate clinical efficacy and adverse drug reactions of patients.
All three patients were male, aged 38-58 years. Acinetobacter baumannii was detected in bronchoalveolar lavage fluid and blood cultures, with susceptibility testing indicating resistance to carbapenem antibiotics. After treatment of Eravacycline, significant improvements were observed in clinical manifestations, inflammatory indicators, and imaging examinations. No Eravacycline-related adverse reactions were identified.
Eravacycline demonstrates favorable efficacy and safety in treating pulmonary infection combined with bloodstream infection caused by multidrug-resistant Acinetobacter baumannii.
