The goal of this quasi-experimental study is to compare the effectiveness of topical adrenaline and 3% hydrogen peroxide for controlling bleeding (hemostasis) during tonsil removal surgery in patients aged 5 to 18 years. The main questions it aims to answer are: 1. Which substance leads to faster bleeding control during surgery? 2. Which substance results in less total blood loss during surgery? Researchers compared the adrenaline group to the hydrogen peroxide group to see if one agent was more effective at managing bleeding than the other. Participants underwent a tonsillectomy where surgeons applied either gauze soaked in adrenaline (1:100,000 solution) or gauze soaked in 3% hydrogen peroxide to the tonsil area to stop bleeding.
