- Brief Summary
Spinal anesthesia (SA) is a widely accepted anesthetic technique for hip fracture repair among elderly. Positioning for SA can be extremely painful. Effective management of pain is important for these patients comfort.
Fascia Iliaca block (FIB) and Femoral nerve blocks are commonly used for analgesia in hip fracture patients. However, they often provide a modest reduction in pain.
The Percapsular Nerve Group block (PENG Block) has the advantage that it covers the accessory obturator nerve.
Aim of the study: compare FIB with PENG prior to positioning hip fracture patients for standardized SA.
In a prospective randomized double blind we included 80 patients aged more than 65 years old, for whom pain was felt when raising the affected limb to 15 degrees. Patients were assigned to receive either ultrasound guided Fascia Iliaca block or Percapsular Nerve Group block using 20 mL Lidocaine 1.5% in both groups. We compared pain on positioning for spinal anesthesia using Verbal Rating Scale (VRS 0 = no pain , VRS 1 = mild pain, t 2= severe pain) for both groups. We also recorded different times to perfom block.
- Detailed Description
The purpose of the study was to compare analgesis effect of Percapsula nerve group block to fascia iliaca block prior to positioning hip fracture patients for standardized SA. We included 80 patients reporting pain with Verbal Rating Scale at 2 when raising the affected limb to 15 degrees. All patients admitted to induction room, were given standard monitoring and we randomized to receive either: ultrasound fascia iliaca block using linear high frequency ultrasound probe (10-15MHz) placed in a transverse direction over the anterior thigh below the inguinal ligament. A 50 mm needle was advanced until the tips placed underneath the fascia iliaca and 20 mL 1.5% Lidocaine was injected or ultrasound Percapsula nerve group block A curvilinear using low-frequency ultrasound probe (2-5MHz) that was initially placed in a transverse plane over the anterior inferior iliac spine and then aligned with the pubic ramus by rotating the probe counter clockwise approximately 45 degrees. In this view, the iliopubic eminence , the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle were observed and than a 100 mm needle was advanced to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly and 20 mL 1.5% Lidocaine.We compared pain on positioning for spinal anesthesia and also different time to realise both blocks.

Group Intervention Description Percapsular nerve group block percapsular nerve group block A curvilinear low-frequency ultrasound probe (2-5MHz) was initially placed in a transverse plane over the anterior inferior iliac spine (AIIS) and then aligned with the pubic ramus by rotating the probe counterclockwise approximately 45 degrees. In this view, the iliopubic eminence (IPE), the iliopsoas muscle and tendon, the femoral artery, and pectineus muscle were observed. A 22-gauge, 100-mm needle was inserted from lateral to medial in an in-plane approach to place the tip in the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. Following negative aspiration, the local anesthetic solution was injected in 5 mL increments while observing for adequate fluid spread in this plane for a total volume of 20 mL of 1.5% Lidocaine. fascial iliaca fascia iliaca block : A linear high frequency ultrasound probe (10-15MHz) was placed in a transverse direction over the anterior thigh below the inguinal ligament. We identified the femoral artery and the iliacus muscle lateral to it, covered by the fascia iliaca. The needle was inserted in plane and a 22 gauge, 50 mm needle was advanced until the tips placed underneath the fascia iliaca. Following negative aspiration, the local anesthetic solution was injected in 5mL increments while observing for adequate fluid spread in this plane for a total volume of 20 mL of 1.5% Lidocaine
