Near-Infrared Spectroscopy (NIRS) in Traumatic Brain Injury (TBI)

Traumatic brain injury (TBI) occurs when a sudden trauma causes damage to the brain. TBI can result head suddenly and violently impacts an object or pierces skull enters tissue. Secondary injuries after traumatic lead impairments on cerebral oxygenation autoregulation. Considering that secondary often take place within first hours trauma, noninvasive monitoring might be helpful in providing early information brain’s condition. Near-infrared spectroscopy (NIRS) is emerging modality based chromophore absorption of infrared light with capability perfusion This review investigates main applications NIRS presents thorough revision those autoregulation monitoring. Databases such as PubMed, EMBASE, Web Science, Scopus, Cochrane library were utilized identifying 72 publications spanning between 1977 2020 which directly relevant this review. The majority evidence found used for diagnosis applications, especially (59%). It was not surprising nearly all patients male adults severe who monitored mostly continue wave spatially resolved invasive device. In general, high proportion assessed papers have concluded could potential technique assessing TBI, despite various methodological technological limitations NIRS.
