We reviewed all patients treated for intoxication in the pediatric ICU (PICU) of the Sainte-Justine Hospital over a 3-yr period. Poisoning (105 patients) constituted 3.1% of PICU admissions. Most involved children less than 3 (42%) yr or greater than 12 (33%) yr. Products most commonly ingested included tricyclic antidepressants (22%), benzodiazepines (15%), theophylline (10%), ethanol (10%), hallucinogens (8%), salicylates (8%), narcotics (8%), antihistamines (7%), and carbamazepine (5%). Three children became comatose after ingesting about 1 g of hashish. Multiple drug ingestions were frequent (22%), particularly in suicide attempts (11/23). Treatment was, in general, interventionist and nonspecific; aggressive measures for poisoning were required in only two patients who were hemodialyzed. Two patients stayed in the PICU greater than 2 days. All patients survived with no sequelae, except for one patient who required an intestinal resection. Poisoning in children is a common occurrence leading to PICU admission; however, the medical prognosis is usually excellent.
