| Abstract: | Cerebral autoregulation and the blood-brain barrier are two important mechanisms that attempt to preserve brain homeostasis. The function of either may be disrupted by injury. When autoregulation is impaired, blood pressure and hematocrit determine cerebral oxygen delivery. Injury to the blood-brain barrier impairs brain volume regulation and may contribute to cerebral edema. The choice of intravenous fluid influences cerebral blood flow, cerebral oxygen delivery, brain metabolism, and brain volume. |
