Measurement of Optic Nerve Sheath in Traumatic Raised Intracranial Pressure
Traumatic Brain InjuryTrauma patients are at risk for serious head trauma. The consequences of serious head trauma are often life altering. Currently, the only method available to rapidly assess the severity of head injury and need for neurosurgical intervention is the CT scan. This time consuming test requires transportation of a potentially unstable patient to the CT scanner. The investigators goal in traumatic brain injury is to identify early those patients who may require neurosurgical intervention. Brain swelling (elevated intracranial pressure) is transmitted to the eye and this can be measured with ultrasound. The investigators hypothesis is that this test will rule out significant elevations in intracranial pressure and perform as well as CT scan in doing this. The investigators study aims to demonstrate that ultrasound of the optic nerve is as good as CT scan in ruling out clinically significant elevations in pressure within the brain. After consent has been obtained, any trauma patient who has an indication to undergo CT scan of the brain will also undergo ultrasound of the eye. A radiologist will then review the CT scans to determine if signs of elevated intracranial pressure are present. The investigators hope to demonstrate that a bedside ultrasound performed in the trauma suite is reliable for ruling out the possibility of elevated intracranial pressure. **Update August 2009** Currently, deferred consent has been obtained from our REB allowing us to defer consent for this intervention of minimal risk. As well, REB has also approved phone consent in the interim.
Cerebral Oxymetry in Traumatic Brain Injury
Traumatic Brain InjuryVasopressor for current treatment protocols for acute traumatic brain injury can lead to vasoconstriction and thus cerebral hypoperfusion that can be detected with cerebral oxymetry as a drop in SCO2.

Loss of Consciousness of Unspecified DurationCerebral Laceration and Contusion1 moreMicrobiome studies may be highlighted as crucial in the development of sleep disorder for TBI patients. The microbiota-gut-brain connection may further provide an opportunity for microbiota manipulation to treat the TBI patients with sleep disorders.This study is to investigate whether exist the relationship between sleep disorder and circadian rhythm of patients with TBI or not and focus the study on the potential of the host-microbiota interaction in regulating sleep disorder.
