Abstract

Introduction: Femur fractures are very painful. The peripheral nerve block provides good analgesia in these patients before performing regional anesthesia. This study aims to compare 2 local anesthestics in femoral nerve block for analgesia in preoperative positioning and postoperative analgesia of patientsMethods: Prospective, randomized study was conducted on 60 patients (18-60 years) of ASA I&II scheduled for femur surgery under combined spinal epidural. anaesthesia In group B (n=30), femoral nerve block(FNB) was performed with 0.2% bupivacaine (30ml) and in group R(n=30), 0.2% ropivacaine (30 ml) was used. Various parameters like numeric rating pain scale, time to spinal anaesthesia, sensory and motor block onset times and durations, time to first analgesic use, intraoperative & postoperative visual analog scale (VAS) data, post- operative epidural top ups, vitals and side effects were recorded for each patient.Results: Pain assessed on visual analogue scale (VAS) during positioning was significantly less in FNB group using 0.2%bupivacaine at 5 minutes. Time to perform spinal block was significantly shorter in FNB group using 0.2% bupivacaine (8.30 min) versus ropivacaine group (17.30 min). But postoperative analgesic requirements were more in ropivacaine group and duration of analgesia was prolonged in bupivacaine group.Conclusion: With bupivacaine time to perform spinal anesthesia was reduced and postoperative analgesia was better with bupivacaine group.
0.2%布比卡因与0.2%罗哌卡因股神经阻滞用于股骨骨折术前定位及术后镇痛的比较
股骨骨折是非常痛苦的。周围神经阻滞为这些患者在进行区域麻醉前提供了良好的镇痛效果。本研究旨在比较两种局麻在股神经阻滞中对患者术前定位和术后镇痛效果的影响。方法:前瞻性、随机研究60例(18-60岁)在联合脊髓硬膜外下行ASA i和ii级股骨手术的患者。麻醉B组(n=30)采用0.2%布比卡因(30ml)行股神经阻滞(FNB), R组(n=30)采用0.2%罗哌卡因(30ml)。记录每位患者的各种参数,如数值评定疼痛量表、脊髓麻醉时间、感觉和运动阻滞发作时间和持续时间、首次使用镇痛药时间、术中和术后视觉模拟评分(VAS)数据、术后硬膜外充值、生命体征和副作用。结果:使用0.2%布比卡因的FNB组体位5分钟时视觉模拟评分(VAS)疼痛明显减轻。0.2%布比卡因FNB组脊髓阻滞时间(8.30 min)明显短于罗哌卡因组(17.30 min)。但罗哌卡因组术后镇痛需求较多,布比卡因组术后镇痛时间延长。结论:布比卡因组腰麻时间缩短,术后镇痛效果较好。
