血流感染者鲍曼不动杆菌耐药性分析(1)
【摘要】 目的 对本院的鲍曼不动杆菌血流感染者进行临床特征及耐药性分析, 为临床有效治疗提供有利证据。方法 23例血流感染者共检测出74株鲍曼不动杆菌,通过纸片扩散法检测鲍曼不动杆菌耐药性。结果 23例鲍曼不动杆菌血流感染者中, 心脑血管疾病11例, 糖尿病12例。头孢曲松钠、头孢唑啉钠、头孢他啶耐药率最高, 分别为39.19%、21.62%、21.62%, 其次为阿奇霉素、克林霉素、氧氟沙星, 耐药率分别为17.57%、13.51%、13.51%, 耐药率分析最低的青霉素液为0。结论 鲍曼不动杆菌的血流感染者中的耐药性分析已明确, 对于药物的有效选择起到了重要的作用。

【Abstract】 Objective To analyze the clinical characteristics and drug resistance of acinetobacter baumannii bloodstream infection patients, to provide favorable evidence for the effective treatment. Methods Clinical data of 23 cases of bloodstream infection by screening of 74 strains of acinetobacter baumannii was retrospectively analyzed, and paper diffusion method was used for drug susceptibility test. Results Among 23 acinetobacter baumannii bloodstream infection patients, there were 11 cases of cardio-cerebrovascular disease and 12 cases of diabetic mellitus. Ceftriaxone sodium, cefazolin sodium, ceftazidime had the highest resistance rate respectively as 39.19%, 21.62% and 21.62%, followed by azithromycin, clindamycin, ofloxacin, with resistance rates respectively as 17.57%, 13.51%, 13.51%, and The lowest resistance rates of penicillin solution was 0. Conclusion The drug resistance analysis in patients with acinetobacter baumannii bloodstream infection has been clear and it has played an important role in the effective selection of drugs.

鮑曼不动杆菌(acinetobacter baumanii)是革兰菌群, 它属于非发酵类、氧化酶阴性、硝酸盐还原试验阴性、没有动力需氧的一种阴性菌[1]。生存力很强的一种细菌。容易存在病房内, 对患者自身的康复带来威胁。对于病原菌的侵袭, 大多临床会选择抗生素来防御, 由于我国抗生素使用不规范, 存在滥用的现象, 导致细菌的耐药越来越严重[2, 3]。因此, 对于如何抵抗鲍曼不动杆菌的侵袭, 选择有效的治疗药物就显得的尤为重要。
1 资料与方法
1. 1一般资料 选取2013年1月~2016年1月内蒙古赤峰市医院病房23例血流感染者作为研究对象, 在其送检标本中共分离出74株鲍曼不动杆菌。
1. 2 方法 通过药敏试验测定鲍曼不动杆菌耐药性。药敏试验采用K-B纸片(英国OXOID公司)扩散法, 取待试细菌于少量灭菌生理盐水中制成细菌混悬液, 用灭菌的棉拭子沾取菌液涂布到培养基表面, 致密而均匀;将含抗生素药物的滤纸片用烧灼灭菌的镊子分别贴于平板表面, 保持一定距离(为了抗菌纸药片与培养基表面密贴, 可用镊子轻按下纸片)纸片紧贴在培养基上, 做好标记。
2 结果
23例鲍曼不动杆菌血流感染者中, 男11例, 占47.83%;女12例, 占52.17%。年龄56~82岁, 平均年龄(61.32±6.17)岁。
其中, 心脑血管疾病11例(47.83%), 糖尿病12例(52.17%)。头孢曲松钠、头孢唑啉钠、头孢他啶耐药率最高, 分别为39.19%、21.62%、21.62%, 其次为阿奇霉素、克林霉素、氧氟沙星, 耐药率分别为17.57%、13.51%、13.51%, 耐药率分析最低的青霉素液为0。其余抗生素耐药性均在10%以下。见表1。, 百拇医药(于浩)
