Summary

This study tested whether a nerve block (suprazygomatic maxillary nerve block) can reduce pain and the need for strong painkillers in children after tonsil and adenoid removal. 114 children aged 6 months to 18 years took part. The block was given during surgery, and some children also received a medication called dexmedetomidine to see if it could make pain relief last longer.
