超声引导下股神经-腘窝坐骨神经阻滞麻醉应用于膝关节镜手术的临床效果

Clinical effect of ultrasound-guided femoral-popliteal fossa sciatic nerve block anesthesia in knee arthroscopic surgery

目的探讨超声引导股神经联合腘窝坐骨神经阻滞麻醉应用于膝关节镜手术的临床应用价值。方法选取本院收治的接受膝关节镜手术的50例老年患者为研究对象,按照麻醉方法不同将其分为观察组(n=25)和对照组(n=25)。观察组给予股神经联合腘窝坐骨神经麻醉,对照组给予腰麻。比较2组患者行膝关节镜手术的时间,麻醉前和麻醉药物注射后5、10、15 min心率和平均动脉压的变化。比较2组患者运动、感觉阻滞起效时间与持续时间。结果2组麻醉前、麻醉药物注射后5、10、15 min心率和平均动脉压比较,差异无统计学意义(P>0.05)。观察组实施联合麻醉后感觉阻滞起效时间和持续时间及运动阻滞起效时间和持续时间显著长于对照组(P<0.05)。结论超声引导股神经联合腘窝坐骨神经阻滞麻醉应用于膝关节镜手术的临床效果显著,术后镇痛效果良好,可有效稳定患者血流动力学。

Objective To study the clinical value of ultrasound-guided femoral nerve-popliteal fossa sciatic nerve block in knee arthroscopic surgery.Methods A total of 50 patients underwent knee arthroscopic surgery were selected as research objects,and were divided into observation group(n=25)and control group(n=25)according to different anesthetic methods.The observation group was given femoral nerve combined with popliteal sciatic nerve anesthesia,and the control group was given lumbar anesthesia alone.The operation time of knee arthroscopic surgeries,changes of heart rate and mean arterial pressure were compared between the two groups before anesthesia and 5,10,and 15 minutes after injection of anesthetic drugs.The sensory and motor block onset time and duration between the two groups were compared.Results There were no significant differences in heart rate and mean arterial pressure between the two groups before anesthesia and 5,10 and 15 minutes after injection(P>0.05).The onset time and duration of sensory block and motor block after anesthesia in the observation group were longer than those in the control group(P<0.05).Conclusion Ultrasound-guided femoral nerve-popliteal fossa sciatic nerve block anesthesia is effective in knee arthroscopic surgery,has better postoperative analgesia effect,and can effectively stabilize the hemodynamics of patients.
