Abstract

Background: Fracture femur is common in elderly. Spinal anesthesia (SA) in elderly patients can be associated with major hemodynamic changes whereas lumbar plexus block (LPB) can provide ideal perioperative analgesia as there is no hemodynamic instability or depression of pulmonary functions. The purpose of this study is to compare the efficacy of SA versus LPB for intraoperative anesthesia and postoperative analgesia in fracture femur surgery.

Materials and Methods: This prospective randomized controlled study was carried out 70 patients of either sex with age >20 years, ASA physical status I - III scheduled for fracture femur surgery. Patients were randomly classified into two equal groups (n = 35); group I (SA) received SA by heavy bupivacaine HCL 0.5% 2.5-3.5 ml and group II (LBP) received posterior LPB by 30-35 ml bupivacaine 0.5%.

Results: The time for performing the block was significantly longer in group LPB than group SA. The onset of sensory and motor block was significantly increased in group LPB than group SA. The intraoperative HR was significantly increased, and intraoperative MAP was significantly decreased in group SA compared to group LPB at 5, 10, 15, 20, 25 and 30 minutes. Postoperative HR and MAP was significantly increased in group SA compared to group LPB at 1 and 6 h. Postoperative VAS was significantly increased in group SA than group LPB at 1 and 6 h. The duration of sensory and motor block was significantly increased in group LPB than group SA. The time of postoperative first analgesic requirement was significantly longer and the total pethidine consumption in the 1st 24 h was significantly lower in group LPB than group SA. SA was associated with significant increase in hypotension, nausea, vomiting and headache.

Conclusion: LPB is an effective alternative to SA as an anesthetic technique for femur fracture surgeries. LBP offers a more stable intraoperative hemodynamics and provides longer duration of analgesia postoperatively with less side effects. However, SA has shorter time for performing the block with earlier onset of sensory and motor block.
