Comparison of Analgesic Efficacy of ESP Block and Caudal Block in Patients Undergoing Hypospadias Surgery

The goal of clinical trial is to compare in of analgesic efficacy of sacrale erector spinae plane (ESP) block and caudal block in participants undergoing hypospadias surgery. Investigators will include children between the ages of 6 months and 7 years in the 1st and 2nd categories in the ASA. In this study, investigators seek answers to the following questions: Which of the sacral (ESP) block and caudal block applied to participants undergoing hypospadias surgery has higher postoperative analgesic efficiency than the other? Which of the sacral ESP block and caudal block applied to participants undergoing hypospadias surgery is superior in duration of analgesia? After general anesthesia is administered to the participants, one of the 2 blocks will be administered in a randomized manner and the relevant data will be recorded. This research will be conducted in a single center as a prospective randomized controlled study. It was planned to include 60 participnts from the ASA I-II pediatric participants aged between 6 months and 7 years, who will undergo hypospadias surgery between December 2022-December 2023, and randomization will be done by closed envelope method. Two groups with sacral ESP and caudal block will be formed, each with 30 participants.
