What this trial studies

This study aims to compare the effectiveness of peribulbar block and sub-tenon block as adjuncts to general anesthesia in children undergoing strabismus surgery. It will assess their impact on the oculocardiac reflex, postoperative pain management, and incidence of postoperative vomiting. A total of 120 children aged 6 to 13 years, classified as ASA I or II, will be included, while those with specific exclusions such as orbital tumors or allergies to anesthetics will be omitted. The study will involve a thorough pre-anesthetic evaluation and standardized anesthesia induction protocols.

Who should consider this trial

Good fit: Ideal candidates are children aged 6 to 13 years scheduled for elective strabismus surgery with ASA I or II classification.

Not a fit: Patients with orbital tumors, significant comorbidities, or allergies to local anesthetics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve postoperative outcomes and pain management in pediatric strabismus surgery.

How similar studies have performed: Previous studies have shown varying success with similar anesthesia techniques, but this specific comparison is novel.
