Children are always curious and explore their world with all their senses, including taste. As a result, the home and its surroundings can be a dangerous place for children to inadvertently ingest toxins. Every year, thousands of children are hospitalized because of poisoning. The forms of poisoning vary by age group, type of material exposed, and the nature and dose of the poison. Acute poisoning (NDC) is when poison enters the body in a short time causing damage to organs and causing danger to the body. If not treated in time, it can cause death. Every year, about 6 million children around the world suffer from food poisoning. In which, children under 5 years old account for 60-80%. Poisoning tends to increase due to the arbitrary use of chemicals and drugs, the causative agents of NCDs are many, so it is difficult to identify. Children under 5 years old have a limited ability to fight and eliminate toxins, so when they are poisoned, they often need emergency care. When the disease is severe, it can easily cause death. However, today, with advances in diagnosis and resuscitation techniques, the mortality rate due to IBD is decreasing. The diagnosis can easily be based on testimonies or items brought. However, there are many cases where it is very difficult, even with toxicology test results. Because the clinical manifestations of acute poisoning in children have many symptoms similar to other causes. Definitive diagnosis is based on: medical inquiry, clinical examination and toxicology test. 2.1. Asking about the disease Asking the patient is a very important job because 90% of the cases can be based on testimonies and family items to determine the cause. Some questions can be asked such as: What do children eat and drink? How much is the food intake? How long does it take to eat? What is the first symptom? Do other people eating and drinking with the same symptoms as children?
