Methods of Monitoring Intracranial Pressure: A Review.

Monitoring intracranial pressure (ICP) is important in a variety of neurologic conditions, including aneurysmal subarachnoid hemorrhage and traumatic brain injury. Monitoring and controlling ICP can mitigate secondary injury of the brain. Of the invasive methods of monitoring ICP, the external ventricular drain is still considered the gold standard. However, microtransducers have been shown to be a reliable option with significantly lower risks of complications. Due to their reproducibility, and their limitations, they are not ready to replace invasive ICP monitoring techniques. This article reviews the commonly used invasive and non-invasive methods of monitoring ICP.
