Official title

Comparison of Analgesic Efficacy of Pericapsular Nerve Group (PENG) Block With Lateral Femoral Cutaneous Nerve Block (LFCB) Versus Lumbar and Sacral Erector Spinae Plane Blocks (L-ESPB and S-ESPB) in Pediatric Hip Surgery: A Randomized Controlled Trial

Overview

This randomized controlled trial (RCT) compares the analgesic effectiveness of two regional anesthesia techniques-Pericapsular Nerve Group (PENG) block combined with Lateral Femoral Cutaneous Nerve Block (LFCB) versus Lumbar and Sacral Erector Spinae Plane Blocks (L-ESPB and S-ESPB)-in pediatric patients undergoing hip surgery.

Detailed description

Orthopedic hip procedures in pediatric patients, including osteotomies, arthroscopic interventions, and reconstructive surgeries, often result in significant postoperative pain. Effective analgesia is critical for reducing surgical stress, accelerating rehabilitation, and minimizing opioid use and associated side effects. Regional anesthesia techniques have gained attention for their opioid-sparing effects and enhanced recovery profiles.

This randomized controlled trial aims to compare the analgesic effectiveness of two regional anesthetic approaches:

\- The pericapsular nerve group (PENG) block is combined with the lateral fetal cutaneous nerve block (LFCB), targeting hip joint innervation directly and providing comprehensive sensory coverage.

Lumbar and sacral erector spinae plane blocks (L-ESPB and S-ESPB) employ fascial plane techniques to deliver analgesia by diffusing local anesthetic around nerves innervating the hip region.

This trial aims to establish the optimal regional anesthesia technique and determine the clinical benefits of using dexamethasone and dexmedetomidine as adjuvants. The results will guide clinicians toward evidence-based analgesic protocols in pediatric orthopedic hip surgery, potentially reducing opioid-related complications and improving patient recovery outcomes.
