First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two different anesthesia drugs (remimazolam and ciprofol) used during tonsil and adenoid removal in children. The goal is to see which one causes fewer breathing problems like coughing, airway blockages, or low oxygen levels. About 114 children aged 2-12 will take part to help doctors choose the safer option.
