Comments:
A pinpoint pupil suggests : opiates (Heroin – Morphine – codeine). The hyper salivation, tachypnoea and sweating suggest :Organophosphate poisoning. This drug inhibits ant-cholinesterase activity promoting Ach effects. Treatment consists of anticholinergics < (Atropine dose i.v 0.05 mg/kg repeated every 5-10 min as needed adverse effect tachycardia, dry mouth, blurred vision, and urinary retention). Finally, the use of salicylates in children is well-recognized cause of Reyes syndrome, a condition associated with fulminant hepatic failure. Suspected poisoning in children result in thousands of attendances at A&E department each year. Various drugs cause specific signs when taken in overdose. Careful examination of the child should follow A, B, C protocol.
