连续腰丛神经阻滞在全膝关节置换术中的应用简

目的：探讨连续腰丛神经阻滞在全膝关节置换术中的应用效果。方法将60例行全膝关节置换术患者随机分为两组，各30例。术后观察组采用连续腰丛神经阻滞镇痛，对照组采用股神经阻滞镇痛，比较两组患者术后疼痛水平、副作用发生率、膝关节功能评分及生活质量的差异。结果观察组患者术后6 h、12 h和24 h疼痛水平和副作用发生率均低于对照组（ P ＜0．05或P ＜0．01），膝关节功能评分和生活质量评分均高于对照组（ P ＜0．01）。结论连续腰丛神经阻滞可在全膝关节置换术中发挥积极作用，其可降低患者疼痛水平及并发症发生率，提高患者膝关节功能恢复程度和生活质量。

Efficacy analysis of continuous lumbar p elxus blocks on postoperative analgesia in total knee arthroplasty

Objective To investigate the efficacy of continuous lumbar plexus blocks on postoperative analgesia in total knee arthroplasty .Methods Sixty patients after total knee arthroplasty were divided into two groups .The continuous femoral nerve blocks were used in the control group and the continuous lumbar plexus blocks were used in the observation group .The pain level,complica-tion rates,knee joint function and the life quality were compared between the two groups .Results 6 h,12 h,and 24 h after the opera-tion, the pain level and complication rates of the observation group were lower than that of the control group （ P 〈0.05 or P 〈0.01）, and knee joint function and the life quality of the observation group were better than that of the control group （ P 〈0.01）.Conclusion The method of continuous lumbar plexus blocks has valuable significance in total knee arthroplasty with less pain and lower complica -tion rate,and with improved knee joint function and quality of life .
