血浆置换在儿童危重症中的应用

目的 探讨血浆置换在儿童危重症中应用的疗效及安全性.方法 经股静脉或颈内静脉建立血管通路,应用Prisma血液净化机,对10例PICU危重患儿进行28次血浆置换治疗.患者病种分别为脓毒症合并多脏器功能不全、急性肝功能衰竭、肾移植后急性排斥反应,溶血尿毒综合征、格林-巴利综合征、狼疮性肾炎,所有病例均存在2～5个脏器功能衰竭.结果 每次血浆置换量为(63.5±19.5)ml/kg,血流速度为5～10 ml/(kg·min),置换速度为血流速度的20%～25%.经过血浆置换及综合治疗,10例患儿临床症状及生化指标均有好转,2例分别进行4次血浆置换治疗病情才得到缓解.结果8例存活,2例死亡(急性肝功能衰竭及狼疮性肾炎各1例).28例次均顺利完成血浆置换治疗.治疗中有3例次发生一过性荨麻疹,未见休克、严重出血倾向、感染等严重并发症.结论 血浆置换是治疗儿童严重脓毒症及免疫性疾病的一种有效措施.
