    On military facilities, triage of traumatic brain injuries (TBI) during the influx of casualties from high-intensity conflicts remains crucial. However, the absence of immediately available CT scan imaging has prevented medical teams from effectively screening casualties for immediate surgery or evacuation.1 Thus, based on our experiences in the field, military neurosurgeon and intensivist provided a training course dedicated to health servicemen in using a near-infrared spectroscopy device to perform triage of TBI.

    When screening acute intracranial hematomas, near-infrared spectroscopy measures the differences in the haemoglobin levels between extravascular blood and normal brain tissue, previously described and validated by Robertson et al.2 In this regard, we employed the Infrascanner 2000 (InfraScan, USA), which was designed to detect intracranial hematomas with a volume of >3.5 cc and a depth of <2.5 cm from the surface. This non-invasive optical density (OD) measurement is …
