摘要 目的探讨不同浓度硫酸镁在自体血液回收过程中对红细胞的保护作用。方法 60例全髋关节置换术患者依据血液回收过程中贮血器内硫酸镁浓度的不同随机分为对照组(C组)、5 mmol/L组(M1组)和10 mmol/L组(M2组)3组,每组20例。观察自切皮开始2 h内硫酸镁对各组红细胞回收率(ERR)、红细胞平均体积(MCV)及刚性指数(SI)的影响。结果与术前血相比,C组洗涤血MCV、SI明显升高(均P<0.05)。与C组相比,M1组、M2组ERR明显升高,而洗涤血MCV、SI明显降低(均P<0.05);与C组、M1组相比,M2组ERR升高,而洗涤血MCV、SI明显降低(均P<0.05)。结论全髋关节置换术和自体血液回收过程可影响红细胞体积和变形能力,血液回收过程中维持贮血器内滤过血中硫酸镁浓度为5和10 mmol/L可减轻这种损伤,提高红细胞回收率,且后者效果优于前者。
