简介：【 摘要 】 目的 ：分析医院集中招标采购医用耗材的实践状况及优化对策。 方法 ：归纳、整理相关文献，探讨医用耗材集中招标采购的实践情况，基于此提出相应的优化对策并于我院进行试验，对比试验前后 1 年内 4 个季度招标采购中医用耗材费用占比。 结果 ：我院于 2019 年 1 月开始试用医用耗材集中招标采购优化对策，试验后，招标采购中医用耗材费用占比逐渐降低，而第 3 季度、第 4 季度招标采购中医用耗材费用均低于试验前，数据差异有统计学意义 （ P ＜ 0.05 ） 。 结论 ： 招标评审问题、采购问题是阻碍医用耗材集中招标采购效率的关键因素，为此，就需要建立供应商评价体系，构建信息化审查系统，才能 推动医用耗材集中招标采购制度的健康发展，提高医院的服务质量。

简介：【摘要】爆发性心肌炎起病急骤、病程凶险,患者可于数日内出现急性心力衰竭、心源性休克、严重心律失常甚至猝死,预后极差。当药物治疗无效时,通常需给予积极的机械循环辅助,体外膜肺氧和(ECMO)、主动脉内球襄反搏(IABP)为主要的辅助方法。横纹肌溶解综合征是指由于横纹肌损伤引起细胞的溶解,释放大量肌红蛋白、肌酸磷酸肌酶、乳酸脱氢酶进入外周血液造成的临床综合征,爆发性心肌炎合并恶性心率失常时,患者病情已处于严重阶段,如再合并横纹肌溶解,则病情更为复杂,临床护理难度大。
