ReviewStrategies for the use of mechanical ventilation in the neurologic intensive care unit.
Mechanical ventilation in neurologically injured patients presents unique challenges. Patients with acute neurologic injuries may require mechanical ventilation for reasons beyond respiratory failure. ⋯ Weaning and liberation from mechanical ventilation also require special considerations. These issues are examined in the ventilator management of the neurologically injured patient.

ReviewParenchymal brain oxygen monitoring in the neurocritical care unit.
Patients admitted to the neurocritical care unit (NCCU) often have serious conditions that can be associated with high morbidity and mortality. Pharmacologic agents or neuroprotectants have disappointed in the clinical environment. ⋯ This strategy is based on a variety of monitoring techniques including use of intraparenchymal monitors. This article reviews parenchymal brain oxygen monitors, including the available technologies, practical aspects of use, the physiologic rationale behind their use, and patient management based on brain oxygen.

ReviewManagement of acute spinal cord injury in the neurocritical care unit.
Acute spinal cord injury (SCI) is associated with widespread disturbances not only affecting neurologic function but also leading to hemodynamic instability and respiratory failure. Traumatic SCI rarely occurs in isolation, and frequently is accompanied by trauma to other organ systems. ⋯ Typically this level of care is provided in the neurocritical care unit. This article reviews the pathophysiology of the neurologic, cardiovascular, and pulmonary derangements following traumatic SCI and their management in the critical care setting.

Effective monitoring is critical for neurologically compromised patients, and several techniques are available. One of these tools, cerebral microdialysis (MD), was designed to detect derangements in cerebral metabolism. ⋯ Combined with other brain monitoring techniques, MD can be used to estimate cerebral vulnerability, to assess tissue outcome, and possibly to prevent secondary ischemic injury by guiding therapy. This article reviews the literature regarding the past, present, and future uses of MD along with its advantages and disadvantages in the intensive care unit setting.

ReviewSurgical treatment of elevated intracranial pressure: decompressive craniectomy and intracranial pressure monitoring.
Surgical techniques that address elevated intracranial pressure include (1) intraventricular catheter insertion and cerebrospinal fluid drainage, (2) removal of an intracranial space-occupying lesion, and (3) decompressive craniectomy. This review discusses the role of surgery in the management of elevated intracranial pressure, with special focus on intraventricular catheter placement and decompressive craniectomy. The techniques and potential complications of each procedure are described, and the existing evidence regarding the impact of these procedures on patient outcome is reviewed. Surgical management of mass lesions and ischemic or hemorrhagic stroke occurring in the posterior fossa is not discussed herein.
