Ingestion of a caustic substance in a child
Caustic substances include acids (60–80% vinegar, acid detergents, battery acid, fiberglass hardener) and alkali with a pH = 12 (lye, dishwasher detergent, ammonia, sodium hydroxide). Alkali with a pH > 12.5 and acids with a pH < 2 are especially caustic. Washing the mouth and drinking fluid is an adequate first aid. In general children without symptoms can be followed up at home, but those with symptoms should be referred to a hospital .
