- Brief Summary
Hip surgeries in pediatrics consider as one of the common nowadays surgeries with sever postoperative pain so pain management is essential to decrease postoperative complications, early mobilization and hospital discharge. Traditional use of opioids is associated with many adverse effects such as sedation, dizziness, nausea, vomiting, constipation and respiratory depression.
Previous studies reported that Quadratus Lumborum (QL) Block and Pericapsular Nerve Group (PENG) Block are effective postoperative analgesia in hip surgeries.
In this study we will compare between QL block and PENG Block for effective postoperative analgesia to reduce opioids consumption and subsequently avoid opioid-related adverse effects, early mobilization and early hospital discharge.
- Detailed Description
Developmental dysplasia of the hip (DDH) is a common disease of the pediatrics patients with a rate of incidence 3 to 5 per 1000 children and open surgical reduction of congenital hip dislocation (CHD) is commonly done in paediatrics.
One of the most important challenges in pediatric hip surgeries is postoperative pain management which may result in impaired patient rehabilitation and prolonged hospitalizations.
Opioids are commonly used for postoperative analgesia in various surgeries but their use is associated with many complications such as sedation, dizziness, nausea, vomiting, constipation and respiratory depression. Many types of peripheral nerve blocks, such as the femoral nerve block (FNB) and the lumbar plexus block (LPB), are used for lower limb surgeries as well as anterior quadratus lumborum block (QLB) and Pericapsular nerve group (PENG) block that provide effective postoperative analgesia in lower limb surgeries.
Quadratus Lumborum (QL) block was first described by Rafael Blanco at the 2007 annual meeting of the European Society of Regional Anesthesia (ESRA). The basic concept of the QL block is the deposition of a local anesthetic solution adjacent to the anterolateral aspect of the QL muscle. The spread pattern obtained is similar to that of the landmark-based TAP block, in that there is subsequent extension into the thoracic paravertebral space. Borglum et al. originally described placing the needle tip anterior to the QL muscle using their transmuscular approach.
This technique was later refined by applying a posterior approach, named the "Shamrock method" (with the erector spinae, QL, and psoas muscles as the leaves and the L4 transverse process as the stem). Administering local anesthesia between the QL and psoas muscles ensures a reliable spread into the thoracic paravertebral space.
There are different quadratus lumborum blocks (anterior, posterior and lateral blocks) with different mechanisms of action according to injectate spread. However, there is insufficient evidence to recommend one approach and transducer positioning over another for individual patient populations and specific surgical types.
Pericapsular nerve group (PENG) block is relatively a recent regional technique based on blocking the articular branches to the hip joint with a single injection and is used for perioperative analgesia in hip surgery.
The pericapsular nerve group block (PENG) is a regional anesthetic technique described in 2018, developed primarily in total hip arthroplasties (THA) for postoperative analgesia with motor sparing benefits. The block is thought to provide more complete analgesia to the hip by depositing local anesthetic within the myofascial plane of the psoas muscle and superior pubic ramus.

Group Intervention Description Pericapsular Nerve Group (PENG) block group Pericapsular Nerve Group (PENG) block group PENG block will be done while the child in supine position. Then, a high-frequency (8-15 MHz) ultrasound linear probe of Sonosite M Turbo ultrasonography (FUJIFILM Sonosite, Inc., Bothell, WA, USA) will be placed over the anterosuperior iliac spine and then rotating it 45 degrees to acquire images from lateral to medial of the anterior inferior iliac spine, iliopubic eminence, psoas tendon, and the femoral artery. Then, a 22G, 80 mm spinal needle will be 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. After negative aspiration and a test does (0.5 mL of normal saline), an injection of 0.5 mg/kg of 0.25% bupivacaine into the space between the psoas tendon and the iliopubic eminence. Quadratus lumborum block group Quadratus lumborum (QL) block group The child will be positioned in the lateral position, with the operative side non-dependent. Under complete aseptic precautions, QL block will be given by anterior approach at the level of L4. A linear high-frequency probe of Sonosite M Turbo ultrasonography will be applied vertically above the iliac crest, and a 22G, 80 mm spinal needle will be inserted in the plane from the posterior edge of the probe through the QL muscle in an anteromedial direction. The needle tip will be placed between the Psoas major (PM) muscle and the QL muscle. After negative aspiration, injection of 0.5 mL of normal saline to the space between PM and QL muscles . An injection of 0.5 mg/kg of 0.25% bupivacaine into the fascial plane and the local anesthetic appears to press down the PM muscle in the ultrasound image, the patients will be repositioned to a supine position immediately after the block.
