摘　　要：目的探讨右美托咪定(DEX)复合小剂量瑞芬太尼对腰丛-坐骨神经阻滞下老年髋关节置换术患者术中的静脉优化效应。方法选取2018年7月—2020年7月在文昌市人民医院行髋关节置换术的老年患者90例,采用随机对照表法分为A组、B组和C组,每组30例。A组给予DEX泵注,B组给予小剂量瑞芬太尼泵注,C组给予小剂量瑞芬太尼持续泵注的同时联合DEX泵注,泵注剂量与A、B组相同。各组均在用药10 min后在超声联合神经刺激引导下行腰丛-坐骨神经阻滞。观察并比较各组血流动力学、镇痛和镇静效果,比较患者对麻醉效果的满意度。结果在神经阻滞后(T1),B、C组MAP明显低于A组(均P<0.05);在手术开始后15 min(T2)、手术开始后30 min(T3)及手术完成时(T4),C组MAP明显低于A组和B组(均P<0.05),B组MAP明显低于A组(均P<0.05);在T2~T4时,C组HR明显低于A组和B组(均P<0.05)。在T1~T4时,B、C组RR明显低于A组(均P<0.05)。在T1~T4时,C组VAS评分明显低于A组和B组(均P<0.05);T1~T2时,C组BIS明显低于A、B组(均P<0.01),A组BIS明显低于B组(均P<0.05);T3~T4时,B组BIS明显高于A组和C组(均P<0.05)。C组患者对麻醉满意度(96.67%)明显高于A组(66.67%)和B组(66.67%,χ^(2)=9.017,P=0.003)。结论对腰丛-坐骨神经阻滞麻醉下的老年髋关节置换术患者,在术中给予DEX联合小剂量瑞芬太尼持续泵注,能有效维持血流动力学稳定,并能提供更佳的镇痛和镇静效果,且不良反应小,值得在临床推广使用。Objective To investigate the anesthetic effect of dexmedetomidine(DEX)combined with low dose remifentanil on elderly patients undergoing hip arthroplasty with lumbar plexus-sciatic nerve block.Methods A total of 90 elderly patients undergoing hip arthroplasty in our hospital from July 2018 to July 2020 were randomly divided into group A,B and C,with 30 patients in each group.Group A was given DEX pump injection,group B was given small dose remifentanil pump injection,group C was given small dose remifentanil continuous pump injection combined with DEX pump injection,the injection dose was the same as that of group A and B.All groups were treated with lumbar plexus-sciatic nerve block guided by ultrasound combined with nerve stimulation 10 minutes after administration.Hemodynamics,analgesia and sedation effects were observed and compared in each group,and patients’satisfaction with anesthesia effect was compared.Results After nerve block(T1),MAP of group B and C was significantly lower than that of group A(all P<0.05).At 15 min(T2),30 min(T3)after operation and operation completion(T4),the MAP of group C was significantly lower than that of groups A and B(all P<0.05),and that of group B was significantly lower than that of group A(all P<0.05).At T2-T4,HR in group C was significantly lower than that in groups A and B(all P<0.05).At T1-T4,RR in groups B and C was significantly lower than that in group A(all P<0.05).At T1-T4,VAS score in group C was significantly lower than that in groups A and B(all P<0.01).At T1-T2,BIS in group C was significantly lower than that in groups A and B(all P<0.01),and BIS in group A was significantly lower than that in group B(all P<0.05).At T3-T4,BIS in group B was significantly higher than that in group A and C(all P<0.01).The anesthesia satisfaction of group C(96.67%)was significantly higher than that of group A(66.67%)and B(66.67%,χ^(2)=9.017,P=0.003).Conclusion In elderly patients undergoing hip replacement under lumbar plexus-sciatic nerve block anesthesia,intraoperative admini
