Caval Aorta Index for Fluid Optimization in Traumatic Brain Injury

Traumatic brain injury is a leading cause of death and disability in trauma patients. As the primary injury cannot be reversed; management strategies must focus on preventing secondary injury by avoiding hypotension and hypoxia besides, maintaining appropriate cerebral perfusion pressure, which is a surrogate for cerebral blood flow.
