Presentation

  • Brown to black streak from angle of mouth
  • Brown to black vomitus
  • Brown to black stomach wall
  • Black swollen tongue
  • White (chalky white) teeth
  • Blotting paper appearance of stomach mucosa
  • Ulceration of esophagus (fibrosis and stricture)
  • Perforation of stomach.
  • The stomach resembles a black spongy mass on post mortem
  • Treatment

    For superficial injuries, washing (therapeutic irrigation) is important. Emergency treatments include protecting the airway, which might involve a tracheostomy. Further treatment will vary depending on the severity, but might include investigations to determine the extent of damage (bronchoscopy for the airways and endoscopy for the gastointestinal tract), followed by treatments including surgery (to debride and repair) and intravenous fluids.

    Gastric lavage is contraindicated in corrosive acid poisoning like sulfuric acid poisoning. Bicarbonate is also contraindicated as it liberates carbon dioxide which can cause gastric dilatation leading to rupture of stomach.

    Vitriolage

    Vitriolage is the act of throwing sulfuric acid or other corrosive acids on somebody's face.
