Abstract

Background: Lumber plexus block is technically difficult but with availability of nerve locator, it is relatively easy and reliable technique of anaesthesia. This study was planned to compare lumber plexus block with spinal anaesthesia for postoperative analgesia.
Methods: After obtaining permission from institutional ethical committee total 50 patients of either sex with fracture neck femur belonging to physical status ASA group I to III; posted for routine orthopaedic surgery were selected randomly. Group I (SA) received spinal anaesthesia and Group II (LPB) received posterior lumbar plexus block. Time of onset and level of sensory and motor block were noted. Intraoperative vitals were noted at every 15 minute intervals. Patients were observed for 2 hrs at interval of 30 minutes for postoperative pain using visual analogue scale (VAS), vitals and for complications.
Results: Time required for sensory blockade was more 17.32±2.61 in Group II as compared to 3.76±0.91 in Group I (p<0.05) and time required for motor blockade was higher in Group II (22.76±2.67) as compared to Group I (8.64±0.91) (p<0.05). Hypotension was observed in 15 patients in Group I as compared to 2 patients in Group II. VAS score at interval of 30 min was statistically significant in Group I (3.16±1.11) compared to Group II (1.5±0.51).
Conclusion: LPB provides good sensory and motor block with feasibility to extend block, better haemodynamic stability with less side effects so it is a valuable option as compared to SA with supplementation of sedation in case of insufficient analgesia.
