Key result
The pericapsular nerve group (PENG) block provided adequate postoperative analgesia without significant adverse effects in a review of 16 pediatric patients undergoing hip and pelvic surgeries.
Why the study?
Postoperative pain management for pediatric hip pathologies is challenging due to complex hip innervation, prompting interest in motor-sparing regional techniques like the pericapsular nerve group block to reduce systemic opioid adverse effects.
Does the pericapsular nerve group (PENG) block improve postoperative analgesia in pediatric patients undergoing hip and pelvic surgical procedures?
Does the pericapsular nerve group (PENG) block improve postoperative analgesia in pediatric patients undergoing hip and pelvic surgical procedures?
PENG block appears to be a promising, motor-sparing regional anesthetic technique for postoperative pain management in pediatric hip surgeries, though current evidence is limited to case reports and small series.
May support PENG block for pediatric hip analgesia; leaves open confirmation in randomized trials.
Hip disorders in infants and children may result from congenital, infectious, developmental, inflammatory, neoplastic, and traumatic etiologies. Postoperative pain management associated with hip pathologies can be challenging especially due to complex innervation of the hip and surrounding structures. Given the adverse effect profile of systemic opioids, regional anesthesia offers an excellent alternative with more beneficial adverse effect profile. Various peripheral regional anesthetic techniques have been reported with variable results regarding analgesia and differing adverse effect profiles. The pericapsular nerve group (PENG) block is a novel motor-sparing regional anesthetic technique where the local anesthetic agent is deposited in the musculofascial plane between the psoas tendon and the pubic ramus. The main target is the genicular branches of the femoral, obturator, and accessory obturator nerve, which innervate the hip capsule. The anatomy involved with PENG block is reviewed and previous reports of PENG block in pediatric-aged patients, including single shot or continuous catheter techniques, are reviewed.

Elhamrawy et al. (2024) conducted a review in Hip and pelvic surgical procedures (n=16). Pericapsular Nerve Group (PENG) block was evaluated on Postoperative analgesia (pain scores). The pericapsular nerve group (PENG) block provided adequate postoperative analgesia without significant adverse effects in a review of 16 pediatric patients undergoing hip and pelvic surgeries.
