This study is a prospective, randomized, double-blind clinical trial. Its aim is to evaluate whether adding a pericapsular nerve group (PENG) block to spinal anesthesia can reduce the inflammatory response after hip surgery in children.
Hip surgery in children can cause a strong stress and inflammatory reaction, which may affect pain after surgery, the need for opioid medications, and recovery.
Children aged 3 to 8 years will be randomly assigned to one of two groups: spinal anesthesia alone or spinal anesthesia combined with a PENG block. The main goal is to compare changes in the Systemic Immune-Inflammation Index (SII), a blood-based marker of inflammation, measured before surgery and 24 hours after surgery.
Additional outcomes include other inflammatory markers, postoperative pain, opioid use, time to first rescue pain medication, and side effects.
