New Delhi, May 13 || US researchers have developed a wearable and "smart" lactation sensor to prevent babies from overexposure to the common painkiller acetaminophen.
Acetaminophen, commonly used for postpartum pain management, is also frequently given to babies to treat fever, leading to potential double-dosing through both direct administration and indirectly through breastfeeding.
The drug is the leading cause of acute liver failure in children and the most frequent reason for liver transplants in the US.
The acetaminophen sensor, developed by researchers at the University of Southern California in the US gets incorporated into an ordinary nursing pad and detects acetaminophen in breast milk.
For nursing babies with immature liver metabolism, the presence of acetaminophen in breast milk poses additional risks, said the team in the paper described in the scientific journal Device.
“Lactating mothers face unique health challenges, including nutritional deficiencies, the risk of developing mastitis -- a breast-tissue infection -- and the potential transfer of medications and other substances through their milk,” said Maral Mousavi, Assistant Professor of Biomedical Engineering, at the varsity.
While the currently available methods for measuring levels of acetaminophen or other ingredients in milk are costly, complex, and unavailable for routine use in the home, the team zeroed in on lactation pads -- worn inside a bra to absorb leaking milk.
