Tiny Batteries a Rising Risk for Children
Children and batteries are a dangerous and increasingly
common combination, according to a new CDC report. In 1998, while battery-related
injuries sent 1,900 children to the emergency room, 4,800 cases were reported
in 2010.
Overall, more than 40,000 children were admitted to ERs
nationwide between 1997 and 2010. Almost three quarters of them were 4 years
old or younger. One in 10 children required hospitalization; 14 of them died.
The CDC singled out button batteries as the most
potentially harmful type of battery for young children. These are the round,
button-sized batteries often used to power watches, hearing aids, and other
small devices. They are easy to swallow and can get stuck in the esophagus,
leading to serious injury or death.
Twelve of the 14 deaths were attributed to button
batteries; the remaining two deaths also likely involved them.
“This information is consistent with recent reports
showing an increase in severe or fatal outcomes with button battery ingestions
from 1985 to 2009,” write the authors of the report.
The data, primarily from the National Electronic Injury
Surveillance System, were collected and analyzed by the federal Consumer
Product Safety Commission (CPSC). That agency, the report states, “is urging
the electronics industry and battery manufacturers to develop warnings and
industry standards to prevent serious injuries and deaths from button
batteries.”
Potentially Fatal Complications
Swallowed batteries may pass through the intestines and safely
out of the body. However, they often get lodged in the esophagus. When that
happens, a buildup of the chemical hydroxide may occur, causing dangerous burns
within a couple of hours. Batteries stuck in the throat may also leak alkaline
electrolyte, a corrosive chemical.
Even if the battery does not leak, it can cause harm.
Direct pressure can cut off blood flow to the area where the battery is stuck,
leading to tissue death.
The symptoms of battery ingestion include vomiting,
abdominal pain, fever, and diarrhea, as well as difficulty breathing and
swallowing. Such symptoms, which can be attributed to numerous causes, make it
difficult to diagnose battery ingestion quickly. This is especially true, the
report’s authors point out, when a child swallows a battery when no one is
around to see them do it.
“Another complicating factor arises when incidents are
not witnessed or the diagnosis or treatment of battery ingestion is delayed, as
it was in at least nine of the 14 fatal cases,” the report states. “It is also
important to recognize that children might be reluctant or unable to say that
they ingested a battery or gave one to a sibling.”
Safety Measures
Battery safety standards for children’s toys are dictated
by law. All batteries must be inaccessible in toys designed for children under
age 3, while toys for kids under 12 must make inaccessible batteries under a
certain size.
At least three of the deaths noted in the report were
caused by batteries from devices not meant for children, including a remote car
alarm, a garage door opener, and a radio remote control. A new law being
considered by Congress may require child-proofing for button battery enclosures
on all consumer products.
“Parents and caregivers should be aware of the potential
hazards associated with battery exposure (particularly ingestion of button
batteries) and ensure that products containing them are either kept away from
children or that the batteries are secured safely in the product,” the report’s
authors conclude.
If a child swallows a battery, the CPSC advises that you
immediately contact your local poison control center, your family doctor, or
the 24-hour National Battery Ingestion Hotline at 202-625-3333.
