本例为多重耐药鲍曼不动杆菌引起肺部感染的患者，当地医院予比阿培南联合莫西沙星抗感染，病情未见明显好转，持续出现发热症状。转入我科后予头孢哌酮舒巴坦联合替加环素治疗，患者体温恢复正常，但出现了替加环素相关的严重不良反应，包括血小板（Plt）减少、凝血功能异常和出血症状。停用替加环素后改用依拉环素抗感染，Plt逐渐恢复，凝血功能也逐渐改善，最终患者好转出院。

This case report describes a patient with pulmonary infection caused by multidrug-resistant Acinetobacter baumannii. The patient was initially treated with a combination of Biapenem and Moxifloxacin at a local hospital, but there was no significant improvement in their condition, and they continued to experience fever symptoms. After transfer to our department, the patient was treated with Cefoperazone-Sulbactam in combination with Tigecycline. The patient's body temperature returned to normal, but they developed severe adverse reactions attributed to Tigecycline, including thrombocytopenia, coagulation abnormalities, and bleeding symptoms. Tigecycline was discontinued, and the patient was switched to treatment with Eravacycline, which resulted in a gradual recovery of platelet count and improvement in coagulation function. Eventually, the patient recovered and was discharged.
