Value of toxicological investigation in the diagnosis of acute drug poisoning in children.
In the 2 years 1978 and 1979 specimens from 287 children aged between 10 days and 14 years were received for general toxicological investigations. Of the 95 (33%) cases of confirmed poisoning, the diagnosis was established as a direct result of the analyses in 48 patients. No diagnosis was made in at least 85 (30%) of the remaining cases. Benzodiazepines were the drugs most commonly encountered (33%), followed by barbiturates, glutethimide, and meprobamate (15%), salicylate and paracetamol (15%), tricyclic antidepressants (12%), and ethanol (11%). 36 patients were severely poisoned (grade 3 or 4 coma, or convulsions), although only 1 patent died. There was evidence that drug(s) had been administered without authorisation in at least 7 instances, and in 51 (54%) of the poisoned patients there was sufficient concern about the safety of the child or the mode of administration of the drug(s) to institute legal proceedings (8 cases), involve the social services (25 cases), or arrange further medical appointments (18 cases). Drugs are readily available in most households and offer a means of inflicting injury that is less easily detectable than physical assault. For this reason, comprehensive toxicological investigations should be considered in children not only when they may assist in management but also in the presence of unusual or unexplained symptoms which could be drug-induced.
