摘要 目的探讨右美托咪定对体外循环下心肌缺血再灌注损伤的影响。方法选取2013年5月至2016年5月该院收治的体外循环下心肌缺血再灌注损伤患者120例,根据患者入院就诊编号实施平均分组,单号为参照组,双号为研究组,每组60例。参照组给予0.9%氯化钠溶液恒速输注(0.5μg·kg-1·h-1),研究组则给予等量右美托咪定恒速输注。对比两组患者麻醉诱导前(T0)、主动脉开放后10min(T1)、停机时刻(T2)、停机后4h(T3)、术后1d(T4)各时间点的麻醉效果。结果与T0时比较,两组患者T1-4时超氧化物歧化酶(SOD)、一氧化氮(NO)活性均下降,丙二醛(MDA)、心肌肌钙蛋白T(cTn-T)、肌酸激酶同工酶(CK-MB)均升高,差异均有统计学意义(P〈0.05)。研究组患者T2~4时CK-MB、cTn-T、MDA明显低于参照组,NO、SOD明显高于参照组,差异均有统计学意义(P〈0.05)。结论右美托味定用于体外循环下心肌缺血再灌注损伤患者具有积极的意义,可减轻其损伤情况。
