This the case of a 63 year-old man with end-stage renal disease (on chronic hemodialysis), unstable angina and significantly impaired myocardial contractility with low left ventricular ejection fraction, who underwent off-pump one vessel coronary bypass surgery. Combined continuous levosimendan and norepinephrine infusion (at 0.07 microg/kg/min and 0.05 microg/kg/min respectively) started immediately after anesthesia induction and continued for 24 hours. The levosimendan/norepinephrine combination helped maintain an appropriate hemodynamic profile, thereby contributing to uneventful completion of surgery and postoperative hemodynamic stability. Although levosimendan is considered contraindicated in ESRD patients, this case report suggests that combined perioperative levosimendan/norepinephrine administration can be useful in carefully selected hemodialysis patients with impaired myocardial contractility and ongoing myocardial ischemia, who undergo off-pump myocardial revascularization surgery.
这是一名63岁患有终末期肾病(接受慢性血液透析)、不稳定型心绞痛且心肌收缩力显著受损、左心室射血分数较低的男性患者,他接受了非体外循环单支血管冠状动脉搭桥手术。麻醉诱导后立即开始联合持续输注左西孟旦和去甲肾上腺素(分别为0.07微克/千克/分钟和0.05微克/千克/分钟),并持续24小时。左西孟旦/去甲肾上腺素联合用药有助于维持适当的血流动力学状态,从而促进手术顺利完成和术后血流动力学稳定。尽管左西孟旦被认为在终末期肾病患者中禁用,但本病例报告表明,围手术期联合使用左西孟旦/去甲肾上腺素对精心挑选的、心肌收缩力受损且存在持续性心肌缺血的血液透析患者进行非体外循环心肌血运重建手术可能是有用的。
