超声引导下股神经阻滞在全膝置换术后患者镇痛中的应用

Application of Femoral Nerve Block Guided by Ultrasound in Postoperative Analgesia after Total Knee Arthroplasty

目的评价超声引导下股神经阻滞麻醉在全膝关节置换术后患者镇痛中的应用效果。方法选择进行全膝关节置换术的患者50例作为研究对象,平均分为试验组和对照组。对照组使用静脉泵镇痛,试验组使用超声引导下股神经阻滞镇痛。比较两组术后镇痛效果、麻醉药物使用情况、患膝关节主动屈曲度数、并发症发生情况。结果试验组术后视觉模拟评分法、术后48 h镇痛泵内的麻醉药物芬太尼使用剂量、术后48 h患膝关节主动屈曲度数明显优于对照组,差异均有统计学意义(P<0.05)。结论超声引导股神经阻滞麻醉应用于膝关节手术患者术后镇痛,可有效减轻患者疼痛,改善膝关节功能情况,减少药物剂量,临床效果显著。

Objective To investigate the effect of ultrasound-guided femoral nerve block anesthesia in patients after total knee arthroplasty. Methods 50 cases for total knee replacement surgery in the Department of Orthopedics of our hospital were selected as the research objects, and were divided into experimental group and control group. The control group used intravenous analgesia pump, and the experimental group used ultrasound-guided femoral nerve block. The analgesic effect, the dosage of narcotic drugs, knee joint active flexion and the occurrence of complications between the two groups were compared. Results The postoperative visual analogue score, dosage of fentanyl in postoperative 48 h, knee joint active flexion of the experimental group were significantly better than those of the control group, the differences were statistically significant（P〈0.05）. Conclusion The application of ultrasound-guided femoral nerve block anesthesia in patients with knee joint surgery can effectively relieve the pain, improve the function of the knee joint, reduce the dose of the drug, and the clinical effect is significant.
