As our portable electronic devices get smaller, so do the batteries that power them. Hearing aids, watches, calculators, and toys all run on small “button batteries” about the same size as a coin.
Unfortunately, we have seen an increase in button battery ingestion by children that can result in serious injuries, health complications, and even death.
According to the National Capital Poison Center, nearly 3,500 people accidentally swallow a button battery each year. Furthermore, the American Academy of Pediatrics reported that the increase in severe cases of battery ingestion by children is directly related to the increase in the use of 20 mm lithium batteries.
These 20 mm lithium batteries cause the most severe injuries after ingested. The AAP further reports that nearly 40 percent of the lithium batteries in these cases were from television remote controls.
Parents will be glad to know that in most cases, after a child ingests a battery, the battery heads to the stomach and is later passed out through the intestines. However, if these tiny batteries don’t pass all the way through, they can cause severe injuries and sometimes death.
The esophagus is the most common place for the ingested battery to become stuck. NCPC explains that an electrical charge forms around the lodged battery, generating the caustic chemical, hydroxide.
The result is tissue damage to the windpipe, vocal cords, or heart. A child who has swallowed a battery that lodged in the esophagus may have to endure months or years of surgical repairs. However, if the ingested battery is removed within two hours, he or she can avoid serious injury.
If parents fear that a child has ingested a battery, they can dial the National Battery Ingestion Hotline or a poison control center. (See phone numbers, below.) If possible, have the battery information number available when you call.
The National Battery Ingestion Hotline will use the age of the child and the ingested battery size to determine if an immediate X-ray is required. The National Button Battery Ingestion Hotline is also available for consultation with family doctors and emergency room personnel.
