急性高容量血液稀释对全髋关节置换术患者血清干扰素诱导蛋白10表达的影响

目的 探讨羟乙基淀粉急性高容量血液稀释对全髋关节置换术患者血清干扰素诱导蛋白10(IP-10)表达的影响.方法 选择ASA Ⅰ、Ⅱ级择期全髋关节置换术患者20例,随机分为羟乙基淀粉组(HES组)和乳酸钠林格液组(LR组),每组各10例.2组患者均采用腰麻-硬膜外联合麻醉,于麻醉后以20 ml/kg的剂量和30 ml/(ks·h)的速率分别输入6%羟乙基淀粉和乳酸钠林格液.分别记录手术时间、术中出血量和输血量.分别在麻醉前(TO)、手术开始前(T1)、手术开始后30 min(T2)、手术结束(T3)采外周静脉血测定IP-10含量.结果 HES组术中出血量、输血量显著少于LR组[(560±90)ml与(810±110)ml、(200±100)ml与(600±200)ml,P均＜0.05].与TO时比较,HES组与LR组T2、T3时IP-10浓度明显升高(P均＜0.05);HES组T2、T3时IP-10浓度明显低于LR组[(62.8±13.6)ng/L与(77.3±13.8)ng/L、(65.4±10.2)ng/L与(89.9±15.1)ng/L,P均＜0.05].结论 全髋关节置换术患者用羟乙基淀粉200/0.5进行急性高容量血液稀释,不仅可以减少术中输血,而且可以有效抑制IP-10浓度的升高,有利于机体免疫功能的稳定.

Effect of acute hypervolemic hemodilution on expression of serum chemokine interferon-inducible protein 10 in patients undergoing total hip replacement

Objective To study the effect of acute hypervolemic hemodilution on expression of serum chemokine interferon-inducible protein 10 in patients undergoing total hip replacement.Methods Twenty ASA Ⅰ or Ⅱ patients undergoing elective total hip replacement were randomly divided into 2 groups (n=10 each):HES group and LR group.The patients in HES group received 6% HES 20 ml/kg in rate of 30 ml/(kg·h) after anesthesia.The patients in LR group received Ringer's solution 20 ml/kg in rate of 30 ml(kg·h) after anesthesia.The blood loss,blood transfusion and the time of operation were recorded.Venous blood samples were taken before anesthesia (T0),at the begining of operation (T1),30 min after operation (T2),and at the end of operation (T3),in determination of serum chemokine interferon-inducible protein 10.Results The blood loss and the blood transfusion in HES group were (560±90)ml and (200±100) ml,those were significantly lower than that in LR group[(810±110)ml and (600±200)ml].The IP-10 concentrations were significantly increased at T2～T3 as compared to baseline value at T0 in both groups,but were higher in LP group[(77.3±13.8) ng/L and (89.9±15.1) ng/L]than those in HES group [(62.8±13.6) ng/L and (65.4±10.2) ng/L,P＜0.05].Conclusions Acute hypervolemic hemodilution can abate blood loss and blood transfusion during total hip replacement operation.Preoprative infusion with hydroxyethyl starch can attenuate the immunological depression during operation and anesthesia.
