While attending the class, a 7-year-old Vietnamese boy accidentally swallowed the pen cap of a ballpoint pen into his airway, causing brain damage.

After accidentally swallowing the pen cap into his airway, the child showed symptoms of coughing, difficulty breathing and chest pain. The teacher immediately took the child to the school’s medical room for first aid, then transferred him to the local medical center. On the way, the child stopped breathing and had to undergo cardiopulmonary resuscitation while on the way to the provincial hospital. Here, the child continued to receive cardiopulmonary resuscitation. However, due to brain damage due to lack of oxygen, the child had many continuous seizures, so the doctors quickly transferred the child to the National Children’s Hospital.
