摘要 目的:探讨血液透析患者使用头孢类抗生素过程中发生抗生素脑病的原因。方法:对维持性血液透析中应用头孢类抗生素后出现抗生素脑病3例的临床资料进行回顾性分析。结果:本组均为尿毒症患者,均因感染在维持性血液透析过程中使用头孢类抗生素,使用剂量符合药典规定,均于用药3~4天即出现脑病的症状,表现为意识模糊、躁动不安、幻视等,停用该药或改用其他类抗生素,临床症状消失。结论:慢性肾功能衰竭患者药物排泄速率减慢、血浆半衰期延长,加上头孢类抗生素与血浆蛋白结合、分布及代谢转化过程的改变对其代谢产生的影响,是造成药物在中枢神经系统内累积,发生脑病的主要原因;减少剂量与加大每次用药的间隔时间是防范发生脑病的关键。
