What this Trial Is About

Circumcision is a common surgical procedure performed worldwide, with about 30% of men over fifteen having undergone it. Effective pain management during and after circumcision is crucial, especially in children, where the use of opioids raises concerns due to potential side effects and addiction risks. This study aims to compare two types of dorsal penile nerve block anesthesia techniques to see which provides better pain relief and reduces opioid use in pediatric patients undergoing circumcision. The study involves two groups of male participants under 18 undergoing circumcision. One group will receive the dorsal penile nerve block using ultrasound guidance (RUS-DPNB), while the control group will receive the block based on anatomical landmarks (DPNB). Both methods are performed before surgery in the operating room. Participants are randomized into these groups to ensure reliable comparison. The study is single-blind, meaning only the medical team knows the group assignments. Participants will be monitored from enrollment until discharge, which is typically within one day. Researchers will record opioid consumption converted to morphine equivalents, durations before, during, and after surgery, any complications, and pain levels using validated pain scales such as FLACC, FACES, or Visual Analog Scale. The study aims to gather data on safety and effectiveness of these anesthesia techniques to help improve pain management in circumcisions.
