Injuries and complications from medical devices send more than 70,000 children and teens to the emergency room every year, and about one-fourth of the problems are linked to contact lenses, according to a study by researchers at the Food and Drug Administration.
Eye infections and abrasions were widespread, apparently related in many cases to children wearing contacts too long or not taking proper care of them. Other widespread problems cited in the report include infections in children with ear tubes, skin tears from pelvic devices used during gynecological exams with teenage girls and wounds caused by hypodermic needles breaking off in the skin.
The most severe injuries, however, were linked to implanted devices such as brain shunts, chest catheters for cancer patients and insulin pumps for diabetics.
Researchers continue to look into why the incidents occur, but device malfunctions and misuse are likely causes. The incidents often underscore the tradeoff between medical advances that have enabled chronically ill children to be treated at home and the difficulties families have in providing home care.
Study co-author Dr. Brock Hefflin said the findings could result in new FDA warnings for medical devices, The Associated Press reports.
The study, published in Pediatrics, was released online Monday.
