Traumatic brain injuries can present a lifetime of consequences. Previous studies indicate that hypothermia may be a viable treatment option, but little data has demonstrated efficacy for our youngest patients. Is hypothermia effective in treating pediatric brain trauma patients in a more rigorous research setting? What are the key mechanisms behind this query? Dr. Jamie Hutchison, associate professor of critical care medicine and pediatrics at the University of Toronto, and research director of critical care medicine at the Hospital for Sick Children in Toronto, evaluates the utility of hypothermia treatment for pediatric traumatic brain injuries with host Dr. Mark Nolan Hill.
