Abstract :

Background: There is limited data on comparison of ropivacaine and lignocaine in femoral nerve block in preoperative and postoperative period in terms of analgesia. 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 and postoperative period. Methods: Prospective, randomized study was conducted on 60 patients (18–60 years) of ASA I&II scheduled for femur surgery under combined spinal epidural. In group I (n=30), femoral nerve block(FNB) was performed using nerve stimulator with 0.2% ropivacaine (15ml) and in group II(n=30), 2% lignocaine (15 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, postoperative 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 2% lidocaine at 5 minutes. Time to perform spinal block was significantly shorter in FNB group using 2% lignocaine (8.30 min) versus ropivacaine group (17.30 min). But postoperative analgesic requirements were more in lignocaine group and duration of analgesia was prolonged in ropivacaine group. Conclusion: With lignocaine time to perform spinal anesthesia was reduced but postoperative analgesia was better with ropivacaine group
