Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Pediatric case study where the child’s tongue was stuck in the opening of a hard plastic drink lid Entrapment restricts circulation which causes fluid to build and the tongue becomes more edematous with time There is a risk of ischemia with prolonged entrapment Initially tried 2% viscous lidocaine for analgesia and lubricant The ER recognized that this mucosal, edematous tongue could benefit from the trick for ostomies and rectal prolapses → table sugar! Sugar granules absorb water which decreases tissue edema This option...
