Experts at Washington State University have developed a smart pacifier that may ultimately eliminate the need for invasive blood draws among babies in Newborn Intensive Care Units (NICUs). The new pacifier can continuously monitor sodium and potassium ion levels. These electrolytes are an indicator of dehydration, which is especially dangerous for infants born with health issues.  When the researchers tested the smart pacifier on a select group of newborns, they found the monitoring results were comparable to data gained from the normal blood draws.  “We know that...
