Insertion of Intracranial Monitoring Devices
The main objective of neurointensive monitoring is to maintain adequate cerebral perfusion and oxygenation, and to avoid secondary injury to the penumbra zone while the brain recovers. Cerebral perfusion is reduced, and poorer outcomes are associated with systemic hypotension and intracranial hypertension. Cerebral perfusion pressure (CPP), an indirect measure of cerebral perfusion, incorporates mean arterial blood pressure (MAP) and intracranial pressure (ICP): CPP = MAP − ICP The only way to reliably determine cerebral hypoperfusion is to continuously monitor ICP and blood pressure (Brain Trauma Foundation 2007).
