Overview of Iron Poisoning

Iron poisoning is a serious condition that can occur due to the ingestion of excessive amounts of iron, often from supplements. It is particularly dangerous in children, who may accidentally ingest iron tablets. Symptoms can range from gastrointestinal distress to severe systemic effects, including metabolic acidosis and multi-organ failure.

Symptoms of Iron Poisoning

• Gastrointestinal Symptoms: Nausea, vomiting, diarrhea, and abdominal pain.
• Metabolic Effects: Lactic acidosis and hypoglycemia.
• Cardiovascular Symptoms: Shock, arrhythmias, and hypotension.
• Neurological Symptoms: Lethargy, seizures, and coma in severe cases.

Standard Treatment Approaches

1. Initial Assessment and Stabilization

Upon presentation, the first step is to assess the patient's condition. This includes:

• Vital Signs Monitoring: Check for signs of shock or respiratory distress.
• History Taking: Determine the amount and type of iron ingested, time of ingestion, and any co-ingestants.

2. Decontamination

If the ingestion is recent (typically within 1-2 hours), decontamination may be necessary:
