Caustic ingestions in children are more likely to be accidental while in adults they are more likely to be intentional.
Alkali ingestions are more concerning than acid ingestions
o Acid ingestions:
§ Coagulation necrosis
§ More severe stomach injury
§ Typically eschar forms over the injured area and these patients are at high risk for bleeding and/or perforation when this eschar falls off around 2-3 days.
o Alakali ingestions:
§ Liquefaction necrosis
§ More severe esophageal injury, as well as the pharyngeal tissues, as these are the earliest structures encountered.
§ Most frequent serious early complication is esophageal perforation
§ Most frequent serious late complication is esophageal stricture
· The airway due to intrinsic injury or compression related to edema of surrounding structures.
· Hemodynamic status related to perforation, bleeding, shock.
· Identifying agent if possible.
