摘　　要：本文报道了昆明医科大学第二附属医院4例血液系统疾病合并嗜水气单胞菌血流感染患者的诊疗及转归,进一步明确血培养重要性以及加深临床对此病的认识。选择2017—2021年昆明医科大学第二附属医院收治的血液系统疾病合并嗜水气单胞菌血流感染的4例患者,对患者临床表现、血培养采集及嗜水气单胞菌检出时间、实验室检查、治疗及预后等临床资料进行回顾性分析。本研究中4例病例均为男性血液系统疾病患者,处于化疗后骨髓抑制期粒细胞缺乏,出现发热后采集血培养并检出嗜水气单胞菌,4例患者血培养报阳时间4~11 h。药敏检测结果显示对二代、三代、四代头孢类抗生素、喹诺酮类抗生素、碳青霉烯类抗生素敏感性较高。4例患者早期均使用亚胺培南-西司他丁钠进行经验性抗感染治疗,1例患者经积极抗感染及升白细胞等治疗后痊愈。1例患者未完成化疗,患者要求出院,后续不详。2例患者迅速发展为坏死性筋膜炎,后患者死亡。研究表明,血液系统疾病合并嗜水气单胞菌血流感染罕见但死亡率高,对于反复发热考虑感染致病的患者需尽早进行血培养确认病原体并进行药敏试验,临床治疗时应结合患者情况及时调整治疗,除抗感染治疗外同时要提升患者免疫力,警惕发展为坏死性筋膜炎。To report the diagnosis, treatment and outcome of 4 patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection in the Second Affiliated Hospital of Kunming Medical University, further clarify the importance of blood culture and deepen the clinical understanding of the disease. Four patients with hematological diseases complicated with Aeromonas hydrophila bloodstream infection treated in the Second Affiliated Hospital of Kunming Medical University from 2017 to 2021 were recruited as the study objects. The clinical manifestations, blood culture collection, detection time of Aeromonas hydrophila, laboratory examination, treatment and prognosis of the patients were retrospectively analyzed. In this study, 4 cases were male patients with hematological diseases, who were in myelosuppression after chemotherapy. After fever,blood culture was collected and Aeromonas hydrophila was detected. The positive time of blood culture in 4 cases ranged from 4 to11 hours. The results of antibiotic sensitivity showed that it was highly sensitive to the second, third and fourth generation cephalosporins, quinolones and carbapenems. Four patients were treated with imipenem cilastatin sodium in the early stage, and one patient recovered after active anti infection and leukocyte raising treatment. One patient did not complete chemotherapy due to a request for discharged, and the follow-up was unknown. Two patients developed rapidly into necrotizing fasciitis and died later. Hematological diseases complicated with Aeromonas hydrophila bloodstream infection are rare, but the mortality rate is high. For patients with repeated fever and considering infection, blood culture should be carried out as soon as possible to confirm the pathogen and drug sensitivity test. During clinical treatment, the treatment should be adjusted in time in combination with the patient’s situation. In addition to anti-infection treatment, the patient’s immunity should be improved and the development of necrotizing fasciiti
