This study aims to evaluate the efficacy of bilateral erector spinae plane block as an opioid-sparing technique for selective dorsal rhizotomy in pediatric patients with spastic cerebral palsy.

Cerebral palsy (CP) is the most common physical disability affecting children. Selective dorsal rhizotomy (SDR) is a neurosurgical procedure that permanently reduces lower limb spasticity in children with CP by selectively targeting and removing sensory rootlets with aberrant activity.

Postoperative pain is often distressing for patients and their families and can result in complications, delayed participation in therapy, and poor functional recovery. Erector spinae plane block (ESPB) is a newly described interfascial plane block. ESPB is effective on both visceral and somatic pain.

Inclusion Criteria:

• Age from 6 to 18 years.
• Both sexes.
• American Society of Anesthesiology (ASA) physical status II, III.
• Patients with spastic cerebral palsy undergoing selective dorsal rhizotomy.

Exclusion Criteria:

• Allergy to local anesthetics.
• Severe fixed joint deformity.
• Previous orthopedic surgery.
• Patient with abnormal liver/kidney function.
• Patient with skin damage or infection at the proposed puncture site.

The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
