Comparison of Erector Spinae Plane Block and Caudal Block for Postoperative Analgesia in Pediatric Patients Undergoing Orchiopexy: A Prospective Observational Study

This study aims to compare the analgesic efficacy of ultrasound-guided erector spinae plane block and caudal block for postoperative pain management in pediatric patients undergoing orchiopexy. Postoperative pain scores, time to first rescue analgesic requirement, total analgesic consumption, and block-related adverse effects will be evaluated during the first 24 hours after surgery. The study will assess whether erector spinae plane block provides effective postoperative analgesia comparable to or superior to caudal block in pediatric orchiopexy.

Inclusion criteria

Children aged 1 to 7 years with ASA physical status I-II undergoing unilateral orchiopexy surgery.

Exclusion criteria

ASA physical status ≥ III
History of prematurity (gestational age < 37 weeks) Known coagulation disorders or bleeding tendency
Infection, inflammation, or skin lesion at the injection site
Known neurological or neuromuscular diseases
Presence of significant cardiac or pulmonary disease (e.g., congenital heart disease, active asthma)

Treatment and study plan

Primary outcomes

Time To First Analgesic Requirement After Surgery

Time frame: First 24 hours postoperatively

The time elapsed from the end of surgery to the administration of the first rescue analgesic

Secondary outcomes

FLACC Pain Scores at Specified Time Intervals

Time frame: first 24 hours postoperatively

Pain assessment using the Face, Legs, Activity, Cry, Consolability (FLACC) scale (score range: 0-10; higher scores indicate worse pain) at 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours and 24 hours postoperatively
