摘要 目的研究参麦注射液对老年患者腹部手术中氧化应激的治疗作用。方法择期首次行腹部手术老年患者32例,随机分成对照组和实验组,各16例。全部病例在气管内全麻下行腹部手术,开放静脉后(T1,基础值)、切皮后10min(T2)、切皮后30min(T3)、关腹时(T4)及拔管后10min(T5)5个时间点取中心静脉血。实验组在开放静脉后用注射泵注射参麦注射液20mL/h。采用比色法分别测定患者的血清活性氧(O2.OH.)、谷胱甘肽过氧化物酶(GSH-PX)、丙二醛(MDA)、总抗氧化能力(T-AOC)及抗超氧阴离子指标。结果活性氧:两组间对比活性氧值无统计学差异,实验组T4和T5时活性氧值明显低于T1(P<0.05)。谷胱甘肽过氧化物酶:两组间对比无统计学差异,对照组T3,T4和T5,实验组T3和T4明显低于T1对照值(P<0.05)。丙二醛和总抗氧化能力:两组间组内MDA值和T-AOC值无统计学差异。抗超氧阴离子:两组间T4和T5时抗超氧阴离子差异有显著性(P<0.05),与T1对比,对照组在T4和T5时显著降低(P<0.01),而实验组差异无显著性。结论参麦注射液对腹部手术老年患者的氧化应激有一定的抑制作用。
