Dynamic and Static Autoregulation After Brain Injury

Serial Measurement of Static and Dynamic Cerebrovascular Autoregulation After Brain Injury

The aim of the study assesses static and dynamic cerebrovascular autoregulation daily over one week in patients with traumatic brain injury or intracranial hemorrhage to quantify the temporal profile of the autoregulatory status.

Inclusion Criteria:

• Traumatic brain injury
• Intracranial hemorrhage

Exclusion Criteria:

• Measurement of TCD were impossible
• Injury of the legs (if the both tigh cuffs for dynamic autoregulation could not be fixed)
