AbstractThe subspecialty of neurocritical care has grown significantly over the past 40 years along with advancements in the medical and surgical management of neurological emergencies. The modern neuroscience intensive care unit (neuro-ICU) is grounded in close collaboration between neurointensivists and neurosurgeons in the management of patients with such conditions as ischemic stroke, aneurysmal subarachnoid hemorrhage, intracerebral hemorrhage, subdural hematomas, and traumatic brain injury. Neuro-ICUs are also capable of specialized monitoring such as serial neurological examinations by trained neuro-ICU nurses; invasive monitoring of intracranial pressure, cerebral oxygenation, and cerebral hemodynamics; cerebral microdialysis; and noninvasive monitoring, including the use of pupillometry, ultrasound monitoring of optic nerve sheath diameters, transcranial Doppler ultrasonography, near-infrared spectroscopy, and continuous electroencephalography. Neuro-ICUs are also capable of specialized neuroprotective management of medical complications, including sodium disorders, renal failure, respiratory failure, and hypertension. These units depend on an interdisciplinary team including speech and language pathologists, occupational and physical therapists, and social workers and case managers, who work to implement early mobilization and successful transition to rehabilitation centers. There are numerous models of neuro-ICUs ranging from "open" units in which patients are cared for in an ICU by an admitting attending, generally without involvement of an intensivist, to "semi-open" units in which intensivists act as consultants, to "closed" units in which the neurointensivist is the admitting attending. The utilization of neuro-ICUs is associated with improved outcomes including lower mortality rates, decreased ICU and hospital length of stay, and improved functional outcomes.Copyright © 2024 The Authors.
