超声引导下CFNB与CACB应用于全膝关节置换术后的效果比较

Comparison of the effects of ultrasound-guided CFNB and CACB in total knee arthroplasty

目的:探讨全膝关节置换术后患者分别运用连续股神经阻滞(CFNB)和连续收肌管阻滞(CACB)的临床效果。方法:选取行全膝关节置换术的患者100例,将其随机分为对照组和观察组,每组各50例。对照组行超声下CFNB,观察组行超声下CACB,分析比较两组患者术后膝关节活动度及术后股四头肌肌力评分情况。结果:随着术后时间的推移,两组患者的膝关节活动度及术后股四头肌肌力均呈上升趋势,但观察组活动度及股四头肌肌力均高于对照组(P<0.05),两组患者术后静息、运动下的疼痛视觉模拟评分(VAS)比较差异无统计学意义(P>0.05)。结论:对全膝关节置换术后患者分别运用超声引导下CFNB和CACB后临床镇痛效果相当,但CACB能提高患者的膝关节活动度和股四头肌肌力,更有利于患者的康复。

Objective:To investigate the clinical effects of continuous femoral nerve block(CFNB)and continuous adductor tube block(CACB)on patients after total knee arthroplasty.Methods:A total of 100 patients who underwent total knee arthroplasty in orthopedics were randomly divided into the control group and the observation group,with 50 cases in each group.The control group underwent CFNB under ultrasound,the observation group underwent CACB under ultrasound,and the postoperative knee joint mobility and postoperative quadriceps muscle strength scores were analyzed and compared between the two groups.Results:With the passage of postoperative time,the knee joint mobility and quadriceps muscle strength of the two groups showed an upward trend,but the mobility and quadriceps muscle strength of the observation group were higher than those of the control group(P<0.05).There was no significant difference in visual analogue scores(VAS)of pain and rest during exercise between the two groups of patients after operation(P>0.05).Conclusion:For patients undergoing total knee arthroplasty,the clinical analgesic effects of CFNB and CACB under ultrasound guidance are equivalent,but CACB can significantly improve the knee joint mobility and quadriceps muscle strength,which is more conducive to the rehabilitation of patients.
