Overview

To evaluate and compare the effectiveness of the Pericapsular Nerve Group (PENG) block alone versus the PENG block combined with the Lateral Femoral Cutaneous Nerve (LFCN) block in providing adequate analgesia for patient positioning during spinal anesthesia in individuals undergoing surgery for hip fracture.

Detailed description

Hip fractures are common among adult patients and often necessitate urgent surgical intervention. Positioning these patients for spinal anesthesia in sitting position is often difficult due to intense pain from the fracture. PENG block is a novel regional technique that targets the articular branches of the femoral nerve, obturator nerve, and accessory obturator nerve, providing excellent anterior hip analgesia sparing the motor function. It is performed under ultrasound guidance and has shown promising results in perioperative pain management. By combining LFCN block with the PENG block, more complete sensory blockade may be achieved. The effectiveness of this combination has not yet been adequately studied, particularly regarding positioning for spinal anesthesia. Therefore, this trial aims to compare the analgesic efficacy of PENG block alone versus PENG +LFCN block in this specific context.

Interventions

  • Procedure PENG Block
    Pericapsular Nerve Group Block
  • Procedure LCFN block
    Lateral Femoral Cutaneous Nerve block
  • Drug bupivacaine 0.25%.
    0.25% of Bupivacaine (Bupivacaine 0.5% is added to Lidocaine 2% in the same volume)
  • Drug Xylocaine 2 %
    local infilteration at the insertion site

Primary outcome measures

  • To compare the time taken to achieve optimal positioning for spinal anesthesia in both groups [Time frame: from initiation of patient positioning until optimal positioning is achieved during the spinal anesthesia procedure]
Secondary outcome measures (4)
  • To assess Numerical Rating Pain Score in both groups at 0,5,10 and 15 minutes post block [Time frame: at baseline (0 minutes) and at 5,10 and 15 minutes after completion of the block]
  • To assess patient satisfaction and comfort during positioning using Likert scale [Time frame: during patient positioning 15 minutes after completion of the block]
  • To monitor mean arterial blood pressure [Time frame: at baseline (0 minutes) and at 5,10 and 15 minutes after completion of the block]
  • To monitor heart rate [Time frame: At baseline (0 minutes) and at 5,10 and 15 minutes after completion of the block]

Eligibility criteria

Inclusion criteria
