摘要: 目的:探讨急性高容量血液稀释(AHH)联合控制性降压(CH)对脊柱手术患者失血量、内稳态及β2-微球蛋白(β2-MG)、胱抑素-C(Cys-C)水平的影响。方法:选取脊柱手术患者72例,随机分为观察组(36例)与对照组(36例)。观察组麻醉后输注6％羟乙基淀粉(130/0.4)20 ml/kg,手术开始后输注硝酸甘油0.2~1.0 μg/(kg·min)行CH,使MAP下降并维持在55~65 mmHg(1 mmHg=0.133 kPa)。对照组仅采用CH。于AHH前(T0)、AHH后CH前(T1,对照组为置管后CH前)、CH后30 min(T2)和停止CH后30 min(T3)测定2组动脉血pH值、剩余碱、K+、Na+、Ca2+、Cl-浓度及β2-MG、Cys-C水平,比较2组术中出血量和输血量。结果:观察组T1、T2、T3时的pH值较T0时及对照组降低(P＜0.05),剩余碱、K+、Na+、Ca2+、Cl-无明显变化;观察组T1时β2-MG、Cys-C水平较T0时下降(P＜0.05),T1、T2、T3时低于对照组(P＜0.05)。对照组T2、T3时β2-MG、Cys-C水平较Tl时升高(P＜0.05)。观察组术中失血量、输血量明显少于对照组(P＜0.05),尿量多于对照组(P＜0.05)。结论:与单纯CH比较,AHH联合CH可明显减少术中出血,对患者的内环境和肾功能的影响较小。Abstract: Objective:To observe the influences of acute hypervolemic hemodilution(AHH)by hydroxyethyl starch solution combined with controlled hypotension(CH)by nitroglycerin on blood loss,homeostasis and β2-MG,Cys-C in spinal surgery patients.Method:Cases of 72 spinal surgery patients were divided randomly into observation group(n=36)and control group(n=36).The patients in observation group were infused 6% hydroxyethyl starch solution(130/0.4)20 ml/kg after anesthesia,at the same time nitroglycerin was infused at a rate of 0.2 to 1.0 μg/(kg·min)and MAP was maintained at 55 to 65 mmHg.CH was implemented in control group according to observation group.Arterial blood pH,residual base and K +,Na +,Ca2 +,Cl,β2-MG,Cys-C at T0(prior to AHH),T1(after AHH for observation group,after cathetering for control group),T2(30 min after CH)and T3(30min after stopping CH)were determinated in two groups.Intraoperative blood loss and blood transfusion were compared between two groups.Result:Compared with T0and control group,pH value decreased significantly(P＜0.05)and residual base,K+,Na+,Ca2+ and Clhad no obvious changes at T1,T2and T3in observation group.Compared with that at T0,the levels of β2-MG and Cys-C at T1decreased significantly(P＜0.05)in observation group,and the levels of β2-MG and Cys-C at T1,T2 and T3 were lower significantly than those in control group(P＜0.05).Compared with that at T1,the levels of β2-MG and Cys-C at T2 and T3 increased significantly in control group(P＜0.05).Intraoperative blood loss and blood transfusion in observation group were less significantly than those in control group(P＜0.05),and the urine volume was more significantly than that in control group(P＜0.05).Conclusion:Compared with CH,AHH combined with CH can reduce significantly intraoperative blood loss,and have less influence on the patient's internal environment and renal function.
