Intracranial Traumatic Hematoma Detection in Children Using a Portable Near-infrared Spectroscopy Device
Introduction: We sought to validate a handheld, near-infrared spectroscopy (NIRS) device for detecting intracranial hematomas in children with head injury.Methods: Eligible patients were those<18 years old who were admitted to the emergency department at three academic children ’s hospitals with head trauma and who received a clinically indicated head computed tomography (HCT). Measurements were obtained by a blinded operator in bilateral frontal, temporal, parietal, and occipital regions. Qualifying hematomas were a priori determined to be within the brain scanner’s d etection limits of>3.5 milliliters in volume and<2.5 centimeters from the surface of the brain. The device ’s measurements were positive if the difference in optical density between hemispheres was>0.2 on three successive scans. We calculated diagnostic performance measures with corresponding exact two-sided 95% Clopper-Pearson confidence intervals (CI). Hypothesis...
