简介:心肌缺血再灌注损伤(myocardialischemiareperfusioninjury,MIRI)是指心肌组织缺血后再恢复灌注,缺血心肌的损害不仅没有好转反而出现反常增加的现象[1].MIRI是临床医生面临的一大难题[2-4].由于心外科手术需要无血、相对静止的环境,在体外循环、心脏停跳下进行,而体外循环心脏停跳下手术则需要阻断心脏供血,注入停跳液促使心脏停跳,心脏上操作完成后再恢复心脏血供,促使心脏复跳,因此体外循环下心脏停跳过程就是一个缺血再灌注损伤的过程.在经历体外循环后的心脏病患者术后恢复过程及远期疗效很大程度与缺血再灌注损伤相关,所以MIRI的研究具有重要的意义.但MIRI损伤的病理生理机制是复杂的,到目前为止都还不完全清楚,亦缺乏有效的治疗策略[5].

简介:目的探讨主动脉内球囊反搏(intra—aorticballoonpump,IABP)治疗急性心肌梗死(acutemyocardialinfarction,AMI)合并心功能衰竭患者的监测与护理。方法回顾性分析9例AMI合并心功能衰竭,并接受IABP治疗患者的临床资料,着重分析监测与综合护理措施。结果术前做好患者心理支持、常规检查、患者备皮及器械准备,术中做好护理配合工作,术后监测病情变化、做好抗凝治疗护理、给予体位指导、观察并发症情况、做好拔管护理。无1例患者拔管后发生出血和血肿,1例患者出现右下肢足背动脉搏动减弱,拔管后症状好转。经治疗,8例患者痊愈出院,1例因多脏器衰竭抢救无效死亡。结论对接受IABP治疗的患者给予科学、规范的护理,保证IABP的正常运作,预防各种并发症是一项重要的护理工作,可有效提高IABP救治AMI并心功能衰竭的成功率,预防并发症的发生。
