Mnemonic for Caustic Esophageal injury

Hi everyone! 

Here is a short mnemonic! 

ACidic Substance = Coagulation Necrosis ( Protein denaturation) - 

results in Eschar - prevents further acid penetration & thereby severe injury.

ALakaline Substance = Liquefactive Necrosis (Cell membrane dissolution) - deeper penetration results in more severe injuries. 

1st step = Serial CXR & abdominal x-ray to identify perforation

If no perforation or respiratory distress then Upper GI endoscopy within 24 hours to assess severity for esophageal damage. 

Thank you!
