Cerebral near-infrared spectroscopy oximeters can alert physicians to premature infants’ exposure to hypoxia. As European researchers push to make this technology a standard clinical tool in neonatal intensive care units, an optoacoustic alternative is emerging.JAMES SCHLETT, EDITOR, [email protected]In 1985, a team of researchers at Duke University Medical Center in Durham, N.C., pointed out the incongruity that, while the goal of intensive care for preterm newborns is to ensure their brains were receiving sufficient oxygen, neonatal intensive care units (NICUs) lacked a direct, noninvasive way to measure cerebral oxygenation. Instead, NICU staff had to rely on indirect methods, such as monitoring blood-oxygen content and transcutaneous oxygen at sites far from the brain, usually the chest or foot. That compelled the researchers to combine near-infrared (NIR) light and spectroscopy as a...Read full articleRelated content from Photonics MediaARTICLESNIR Spectroscopy Enables Accurate Evaluation of OsteoarthritisAn arthroscopic probe, developed at the University of Eastern Finland, could be used to quantitatively assess the health of joint tissues, improving physicians’ ability to detect initial signs...BioPhotonics January 2019 IssueNIRS Surpasses Conventional Diagnostics for OrthopedicsAs the aging population continues to grow, the number of people suffering from musculoskeletal diseases, such as osteoarthritis (OA), is expected to drastically increase.
