A noninvasive technique called near-infrared spectroscopy (NIRS) which gauges how well tissues, including the brain, are oxygenated can help detect problems associated with vital signs in premature babies finds a new study. The findings of this study are published in the Frontiers in Pediatrics journal.
Low-risk noninvasive monitoring, such as continuous cardiorespiratory monitors, can measure heart rate, respiratory rate, and blood oxygenation. A noninvasive technique called near-infrared spectroscopy (NIRS) can gauge how well tissues, including the brain, are oxygenated. While NIRS long has been used to monitor oxygenation in conditions in which blood flow is altered, such as bleeding in the brain, how NIRS values relate to other vital sign measures in NICU babies was unknown.
A research team led by Khodayar Rais-Bahrami, M.D., a neonatologist at Children's National Health System, investigated this question in 27 babies admitted to Children's NICU.
They found that StO2 increased with blood pressure for LBW babies but decreased with blood pressure for MBW babies. Brain and body FTOE in LBW babies decreased with blood pressure. In babies with abnormal brain scans, brain StO2 increased with blood pressure and brain FTOE decreased with blood pressure. Together, the researchers suggest, these measures could give a complete picture of critically ill babies' health.
