Caustic ingestion

[Ernesto]

Caustics (strong acids and alkalis), when ingested, burn upper gastrointestinal tract tissues, sometimes resulting in esophageal or gastric perforation. Symptoms may include drooling, dysphagia, and pain in the mouth, chest, or stomach; strictures may develop later. Diagnostic endoscopy may be required. Treatment is supportive. Gastric emptying and activated charcoal are contraindicated. Perforation is treated surgically.

Worldwide, 80% of caustic ingestions occur in young children; these are usually accidental ingestions of small amounts and are often benign. In adults, caustic ingestions are frequently intentional ingestions of large amounts by suicidal people and are life-threatening. Common sources of caustics include solid and liquid drain and toilet bowl cleaners. Industrial products are usually more concentrated than household products and thus tend to be more damaging.
