They cannot measure the intracranial pressure and drain fluid at the same time: Most EVDs have a relatively simple design.(More on different types of devices for ICP monitoring here: □).Communication with the ventricular system leads to a substantial risk of nosocomial ventriculitis.This may carry a higher risk of infection compared to less invasive monitors. An EVD is the most invasive strategy for measurement of ICP.(4) Intrathecal administration of medications is possible (e.g., chemotherapeutics or antibiotics).(3) Diagnostic sampling of CSF may be performed.(2) Therapeutic drainage of cerebrospinal fluid may be performed (especially in hydrocephalus).(1) Accurate measurement of the intracranial pressure (ICP).(Some other devices don't allow rezeroing, which may cause the pressure to “drift” out of calibration over time.) An EVD is the gold standard approach to measurement of intracranial pressure, because it allows for rezeroing of the pressure transducer as needed.Among critically ill patients, the procedure is usually performed at the bedside. A burr hole is used to penetrate the skull, after which a catheter is blindly advanced into the lateral ventricle using anatomic landmarks.Basics of what an external ventricular drain (EVD) is
