Local injuries by accidental ingestion of corrosive substances by children.

Abstract

Own data and analysis of previous publications show that situations where accidental ingestion of corrosive substances by children may have happened are frequent, but severe corrosive esophagitis leading to perforation or stricture formation is very rare. In case of suspected esophageal injury, esophagoscopy and glucocorticoid treatment become necessary. The evaluation of the initial symptoms in patients from our own material and from the literature indicates that all children with serious esophageal burns had one or more of the following symptoms: visible burns in the oral cavity, hypersalivation, retching, vomiting, retrosternal or epigastric pain, cardiovascular collaps, airway stenosis. Hence, children with an uncertain history of ingestion and without any of these symptoms need not be treated. After ingestion of liquid substances, but never of dry or granular products, lesions in the esophagus without accompanying burns in the oral cavity were observed. The evaluation of 1158 cases of accidental ingestions of several types of household products and a collection of data from the literature on the causticity of these substances shows that cleaners containing mainly detergents and phosphates (with pH values generally between 9 and 11), and household bleaches on sodium hypochlorite basis, are relatively harmless. Drain cleaners (NaOH), decalcifiers (formic acid) and detergents for automatic dish washing machines (metasilicates) are very caustic and are responsible for the majority of serious accidents in children.
