摘要 目的:探讨尼可地尔对联合瓣膜置换术中缺血再灌注损伤心肌的保护作用。方法:选取我院行心脏瓣膜置换手术患者60例随机分为两组,各30例。观察组术前予以尼可地尔10mg干预。对照组未干预。检测两组患者术后6、12h乳酸脱氢酶(LDH)、肌酸磷酸激酶同工酶(CK-MB)和丙二醛(MDA),评估药物作用。结果:术后6h观察组LDH为(378.65±41.56)U/L、CK-MB为(61.78±6.87)U/L、MDA为(6.56±1.52)mmol/mL。对组组分别为(533.96±37.71)U/L、(66.27±8.44)U/L、(7.97±1.76)mmol/mL,各指标差异显著(P<0.05)。术后12h观察组LDH为(318.33±42.28)U/L、CK-MB为(51.54±6.29)U/L、MDA为(5.28±1.02)mmol/mL;对组组为(513.35±35.31)U/L、(64.21±8.03)U/L、(7.67±1.39)mmol/mL,各指标差异显著(P<0.05)。结论:术前应用尼可地尔可明显减少心肌酶、心肌标志物的释放,减轻心脏瓣膜置换术患者心肌缺血再灌注损伤,对体联合瓣膜置换术患者具有良好的心肌保护作用。
