【摘要】 目的　观察高位硬膜外阻滞对围术期患者心肌缺血的疗效。方法　术前确诊心肌缺血且经一般治疗无效或不能耐受硝酸甘油治疗的择期手术患者 6例 ,于T4- 5 间隙行高位硬膜外穿刺 ,头向置管 ,保留 ,以 1 %利多卡因 3mL + 5mL为负荷量 ,使阻滞平面达T1- 5 ,继以 1 %利多卡因 4mL/h持续泵入 ,维持 5～ 7d ,观察治疗前后临床表现、心电图、超声心动或活动平板心电图的变化。结果　全组 6例心肌缺血状况均获得明显改善。结论　高位膜外阻滞用于心肌缺血患者术前准备疗效显著。更多还原

【Abstract】 Objective To observe the effects of high epidural anesthesia(HEA) on peroperative myocardial ischemia.Method Six patients who had been diagnosed myocardial ischemia preoperatively were received HEA with 1% lidocaine(loading dose 3mL+5mL,maintaining dose 4mL/h) for 5 to 7 successive days.Before and after the treatment,the changes of clinical symptom,ECG,UCG and treadmill test were observed.Resu lt After the treatment,myocardial ischemia of all the six patients were improved obviously.Conclusion As a method of preoperative preparation in myocardial ischemia patients,high epidural anesthesia is obviously effective.更多还原
