Abstract
In neuro-intensive care, the estimation of cerebral pressure autoregulation predicts the outcome of brain-injured patients and gives us more information to manage cerebral blood flow and metabolism of the patients. Although various methods using transcranial Doppler ultrasonography were developed, almost all methods were impractical in severe brain-injured patients. In this review, I evaluated several methods to estimate the cerebral pressure autoregulation used in a neuro-intensive care unit.
