Recently, 2-year-old Lele (pseudonym) mistakenly ingested powdered pipeline unclogger, and his family "rinsed" him with water, causing severe chemical and high-temperature burns to his mouth, face, and arms. Currently, the child is still receiving targeted treatment in the hospital, and the tongue damage may affect his pronunciation. Liu Li, Deputy Chief Physician of the Digestive and Nutritional Department at Hunan Children's Hospital, reminds that solid powdered corrosive agents should not be directly rinsed with water after ingestion or contact with the skin, but should be immediately "dried"; If it comes into contact with the skin or lips, gently wipe the remaining powder with a clean cotton cloth or tissue, thoroughly remove it, and then rinse the skin with running water for at least 15 minutes. It is reported that on the day of the incident, Lele accidentally opened the powdered pipeline dredging agent placed in the corner while playing with her sister. Children may find it novel and immediately collapse onto their faces and mouths when they pick it up. At that time, the family didn't see what the object was, and their first reaction was to rinse it with water. And it is this' common sense operation 'that instantly escalates the danger. The strong alkaline component in the pipeline dredging agent releases heat violently when it comes into contact with water, and the splashing high-temperature corrosive liquid not only burns Lele's mouth, but also causes extensive peeling and damage to his facial and arm skin. Liu Li introduced that products such as pipeline uncloggers and strong cleaning agents often contain strong alkaline components such as sodium hydroxide and potassium hydroxide. These substances will undergo a violent exothermic reaction when they come into contact with water, and the temperature will instantly rise. The corrosive substances that were originally only in surface contact will become a double injury of "chemical corrosion+high temperature burns". Even more dangerous is that if the mouth is rinsed with water, corrosive substances may spread to the throat, esophagus, and even be inhaled into the trachea, causing respiratory burns; Splashing liquid can also cause the burn area to expand. Besides not being able to rinse with water, using neutralizing agents, inducing vomiting, and inducing diarrhea on one's own are all incorrect treatment methods that can repeatedly irritate the digestive mucosa with corrosive substances, causing mechanical damage and increasing the risk of perforation and bleeding. ”Liu Li reminds that the correct emergency measure is to first "dry wipe" before seeking medical attention. During this period, it is prohibited to eat or drink anything to avoid exacerbating corrosion or causing coughing. When parents take the child to the hospital, remember to bring the outer packaging of the mistakenly ingested product to facilitate doctors in quickly determining the ingredients and developing precise treatment plans. Data shows that digestive tract corrosion injuries are more common in children under 5 years old, often caused by ingestion of strong acid and alkali cleaning products. This type of injury may lead to postoperative sequelae such as oral mucosal adhesion, difficulty opening the mouth, language pronunciation disorders, and esophageal stenosis. Some injured individuals may need surgery to release the adhesions, which can have a lifelong impact on their families and children. Doctors call on manufacturers of household cleaning agents to standardize product packaging, add prominent toxic and harmful labels, and design child safety locks to reduce risks from the source.
