NeurO2 study receives CIHR Project Grant funding

Congratulations to Alexis F Turgeon, Michael Chasse and Shane W English, principal investigators, and the co-investigators, who have received a Project Grant funding from Canadian Institutes of Health Research (CIHR) for the NeurO2 study.

The NeurO2 study, « optimal brain oxygenation in neurocritically ill patients », is a nested study within two large trials in traumatic brain injury and aneurysmal subarachnoid hemorrhage, HEMOTION and SAHaRA Trials, respectively. These trials are designed to guide clinicians to better understand if maintaining a higher blood level (via transfusion) improves outcomes of the patients. The NeurO2 study uses near-infrared spectroscopy (NIRS) to monitor the effects of the intervention on the measure of brain oxygen delivery. It is hypothesized that, in adult patients suffering from low blood levels (anemia), a low blood oxygen delivery (as measured by NIRS) is associated with poor outcomes, but could be affected by blood transfusion and may serve as a trigger for when to give blood.

The CTRC is proud for having supported the project and providing a forum at its meetings to develop some of the ideas that were included in the proposal.
