Episode 925: Table Sugar for Tongue Entrapment
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...

Educational Pearls:
- Insulin pumps provide a continuous infusion of fast-acting insulin using a basal rate and bolus prior to meals
- Some connect to a continuous glucometer but often blood glucose needs to be checked manually
- Hypoglycemia is rarely due to a malfunctioning pump - there is usually an another external factor
- Hyperglycemia can be caused by underdosing, illness, pump malfunction or expired insulin
- The pump can be used to give a bolus of insulin in the emergency department if necessary
- Stopping the device can be done manually on the device or disconnecting it from the tubing attachment - do not remove the tubing from the skin site if possible
