Primary, spontaneous intracerebral hemorrhage (ICH) confers significant early mortality and long-term morbidity worldwide. Advances in acute care including investigative, diagnostic, and management strategies are important to improving outcomes for patients with ICH. Physicians caring for patients with ICH should anticipate the need for emergent blood pressure reduction, coagulopathy reversal, cerebral edema management, and surgical interventions including ventriculostomy and hematoma evacuation. This article reviews the pathogenesis and diagnosis of ICH, and details the acute management of spontaneous ICH in the critical care setting according to existing evidence and published guidelines.

Acute ischemic stroke is the fourth leading cause of death and the leading cause of disability in the United States. Stroke is a medical emergency. ⋯ Ample evidence has shown that patients presenting early and receiving intravenous thrombolytic therapy have the best chance for significant improvement in functional outcome, particularly if they are transported to specialized stroke centers. Early detection and management of medical and neurologic complications is key at preventing further brain damage in patients with acute ischemic stroke.

ReviewAdverse Neurologic Effects of Medications Commonly Used in the Intensive Care Unit.
Adverse drug effects often complicate the care of critically ill patients. Therefore, each patient's medical history, maintenance medication, and new therapies administered in the intensive care unit must be evaluated to prevent unwanted neurologic adverse effects. Optimization of pharmacotherapy in critically ill patients can be achieved by considering the need to reinitiate home medications, and avoiding drugs that can decrease the seizure threshold, increase sedation and cognitive deficits, induce delirium, increase intracranial pressure, or induce fever. Avoiding medication-induced neurologic adverse effects is essential in critically ill patients, especially those with neurologic injury.

Neuromuscular sequelae are common in the critically ill. Critical illness polyneuropathy and critical illness myopathy are neuromuscular complications of sepsis or iatrogenic complications of treatments required in intensive care. This article discusses the diagnosis, treatment, and prognosis of these disorders based on a literature review. This review found that glycemic control, early mobilization, and judicious use of steroids and neuromuscular blocking agents are the primary approaches to reduce the incidence and severity of neuromuscular complications in affected patients.

ReviewIntracranial Pressure Monitoring and Management of Intracranial Hypertension.
Intracranial pressure (ICP) monitoring is considered the standard of care in the majority of neurosurgical centers in North America and Europe. ICP is a reflection of the relationship between alterations in craniospinal volume and the ability of the craniospinal axis to accommodate added volume. ICP cannot be reliably estimated from any specific clinical feature or CT finding and must be directly measured. This review describes methods of monitoring ICP and how monitoring technique can provide additional information and provides key points regarding the treatment of intracranial hypertension in the neuro-ICU.
