Status epilepticus (SE) is a life-threatening medical and neurologic emergency requiring prompt recognition and treatment. SE may be classified into convulsive and nonconvulsive, based on the presence of rhythmic jerking of the extremities. ⋯ Benzodiazepines are first-line therapy, usually followed by phenytoin/fosphenytoin. A low threshold should exist for obtaining an urgent electroencephalogram.

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.
