摘要
目的:探讨急性高容量血液稀释(AHH)联合控制性降压(CH)对全髋关节置换(THA)患者C反应蛋白(CRP)、白细胞介素-6(IL-6)水平的影响。方法:选取2015-03—2018-03行全髋关节置换术患者90例,随机分为A组、B组和C组,每组30例。麻醉平稳后,A组以30 ml/min的速率静脉输入6%羟乙基淀粉,实施AHH;B组在AHH基础上给予硝酸甘油0.5~5.0μg(/kg·min)行CH;C组不实施AHH和CH。记录3组手术时间、术中失血量、尿量和输血量。记录羟乙基淀粉输注前(C组为手术前30 min,T_0)、羟乙基淀粉输注后(C组为手术开始时,T_1)、手术开始后2 h(T_2)、手术结束时(T_3)、术后24 h(T_4)血浆CRP、IL-6水平。结果:①B组术中失血量明显少于A组、C组(P<0.05),A组、B组尿量明显多于C组(P<0.05),A组、B组输血量明显少于C组(P<0.05),B组输血量明显少于A组(P<0.05)。②与T_0比较,T_2~T_4时3组CRP、IL-6水平显著升高(P<0.05),A组和B组T_1~T_4时CRP、IL-6水平均显著低于C组(P<0.05),A组和B组T_1~T_4时CRP、IL-6水平比较差异无统计学意义(P>0.05)。结论:AHH联合CH不仅可显著减少全髋关节置换术患者术中失血及异体输血,而且可有效抑制围术期CRP、IL-6的表达水平。
Objective:To explore the influence of acute hypervolemic hemodilution(AHH)combined with controlled hypotension(CH)on CRP and IL-6 levels in patients with total hip arthroplasty(THA). Method:90 cases of patients with THA were enrolled in this study.All patients were divided randomly into group A(n=30),group B(n=30)and group C(n=30).The patients in group A were infused 6% hydroxyethyl starch 130/0.4(6% HES 130/0.4)at a rate of 30 ml/min after anesthesia,the patients in group B were received CH with nitroglycerin at a rate of 0.5-5.0 μg/(kg·min) on the basis of AHH,and AHH and CH did not implemented in group C.Operation time,intraoperative blood loss,amount of urine and blood transfusion were recorded in three groups.The plasma CRP and IL-6 levels before hydroxyethyl starch infused(30 min before surgery in group C,T_0),after hydroxyethyl starch infused(at the beginning of surgery in group C,T_1),2 h after the start of surgery(T_2),at the end of surgery(T_3)and 24 h after surgery(T_4)were recorded in three groups. Result:① Intraoperative blood loss in group B was less significantly than that in group A and group C(P<0.05),urine volume in group A and group B were more significantly than that in group C(P<0.05),blood transfusion amount in group A and B group were less obviously than that in group C(P<0.05),and blood transfusion amount in group B was less significantly than that in group A(P<0.05).② Compared with T_0,CRP and IL-6 levels at T_2-T_4 increased significantly in three groups(P<0.05),CRP and IL-6 levels at T_1-T_4 in group A and group B were lower significantly than those in group C(P<0.05),and CRP and IL-6 levels at T_1-T_4 between group A and group B had no statistical significance(P>0.05).Conclusion:AHH combined with CH can reduce significantly intraoperative blood loss and allogeneic blood transfusion in patients with THA,and restrain effectively perioperative expression levels of CRP and IL-6.
