Background: In both developed and developing nations, childhood poisoning is a significant source of morbidity. The majority of poisoning incidents involving teenagers happen accidentally and are brought on by liquid intake. Case Presentation: A 6-year-old school-aged child with possible organophosphate pesticide poisoning was sent to the emergency department. At the time of his arrival at the emergency department, the patient's mental condition had already been injured. He had a moderate traumatic brain injury when he entered the emergency room and scored an 9/15 on the Glasgow Coma Scale. His medical examination upon arrival revealed lacrimation, hypersalivation, a dry mouth, and pinpoint pupils. Atropine (0.05 mg/kg) was administered intravenously to him once in the emergency room. In pediatric critical care unit, he received continuous infusions of pralidoxime at a rate of 10 mg/kg/hour for 16 hours after receiving an intravenous infusion of atropine at a rate of 1 mg/kg/hour for the first 4 hours, followed by 2 further atropine infusions at a rate of 1 mg/kg/hour for the next 4 hours. Conclusion: Globally, childhood poisoning is a major cause of hospitalization, disability, and death. Ingesting organophosphates can lead to poisoning in children.
