超声引导下持续股神经阻滞在全膝关节置换术后的应用效果OA

Objective:To investigate the application effect of ultrasound-guided continuous femoral nerve block after total knee arthroplasty.Methods:78 patients who received total knee arthroplasty in our hospital from June 2019 to April 2021 were selected as the study objects,they were divided into a conventional group and an experimental group according to the odd-even sequence visit number,with 39 cases in each group.The conventional group was treated with intravenous controlled analgesia,the experimental group was treated with ultrasound-guided continuous femoral nerve block.Results:At 6,12,24 and 48 h after surgery,the scores of Pain Visual Analogue Scales in the experimental group were lower than those of the conventional group,the differences were statistically significant between the two groups(P＜0.05).At 48 h after surgery,C-reactive protein and interleukin-6 in the experimental groups were lower than those in the conventional group,the differences between groups were statistically significant(P＜0.05).The total incidence of adverse reactions in experimental group was 7.69%,which was lower than 12.82%in conventional group,and the difference was statistically significant(P＜0.05).After treatment,the percutaneous arterial oxygen saturation of experimental group was higher than that of conventional group,and the difference was statistically significant(P＜0.05).Conclusion:Ultrasound-guided continuous femoral nerve block can effectively relieve pain after total knee arthroplasty,and can reduce the inflammatory response of patients with high safety.
