“Time Lost is Brain Lost” In patients with head trauma the early screening for intracranial bleeding is critical. The timing of any required neurosurgical intervention is a major factor affecting patient outcomes. The Infrascanner is a portable screening device that uses Near-Infrared (NIR) technology to screen patients for intracranial bleeding, identifying those who would most benet from immediate referral to a CT scan and neurosurgical intervention.In the triage of head trauma patients, the Infrascanner can identify patients most likely to have intracranial bleeding. A 431 patient, multi-center clinical trial, demonstrated that the Infrascanner was better than a physical examination alone in identifying patients at high risk of intracranial bleeding. The Infrascanner is light-weight and handheld, and provides a simple, positive or negative graphic report and can be used as a simple extension of the routine neurological examination. The Infrascanner is not a replacement for a CT scan. It is a simple, easy-to-use screening tool which can be used to identify high-risk patients, who can then be prioritized for transportation to a trauma center where a CT scan and neurosurgical treatment is available. Infrascanner Detection Abilities: Patient measurement is completed within 2-3 minutes. Can detect hematomas greater than 3.5 cc in volume. Detects hematomas up to 2.5 cm deep from the surface of the brain (or 3.5 cm from the skin surface). Accuracy: In patients with Epidural, Subdural and Intracerebral hematomas: Sensitivity = 88% / Specicity = 90.7%* * C. Robertson, E. Zager, R. Narayan, N. Handly, A. Sharma, D. Hanley, H. Garza, E.

Infrascanner Technology – How it works Extra-vascular blood absorbs NIR light more than intra-vascular blood since there is a greater concentration of hemoglobin (usually 10 fold) in an acute hematoma than in the brain tissue where blood is contained within vessels. The Infrascanner measures the difference in NIR light absorption at corresponding locations on the left and right sides of the head. The detection depth is supercial (within 3.5 cm of the skin surface), where blood migrates in most cases of bleeding. Infrascanner Clinical Applications Hospital Emergency Room (ER) Screening...
