Seizures are commonly encountered in the setting of brain injury in neurologic critical care. Though seizure prophylaxis with the use of antiepileptic drugs is frequently utilized in variety of brain injury paradigms, it is often not based on evidence and is controversial. Significant difficulties arise from interpretation of supporting literature due to lack of definitions for early-vs.-late-seizures, variable end points with seizure prophylaxis, as well as methodologic inconsistencies for seizure detection. This descriptive review summarizes the existing literature on the use of prophylactic anticonvulsants in clinical paradigms commonly encountered in neurologic critical care and highlights the important controversies concerning their use.

S100B is a protein biomarker that reflects CNS injury. It can be measured in the CSF or serum with readily available immunoassay kits. The excellent sensitivity of S100B has enabled it to confirm the existence of subtle brain injury in patients with mild head trauma, strokes, and after successful resuscitation from cardiopulmonary arrest. ⋯ In the future, S100B measurements might reliably predict secondary brain injury and enable physicians to initiate therapeutic interventions in a timelier manner. S100B levels have been shown to rise hours to days before changes in ICP, neurological examinations, and neuroimaging tests. S100B levels may also be used to monitor the efficacy of treatments.

To describe features in patients admitted to the intensive care unit (ICU) for poor-grade aneurysmal subarachnoid hemorrhage (SAH) and to identify predictors of 12-month outcome. ⋯ Patients in poor clinical condition after SAH have more than a 50:50 chance of a favorable outcome after 1 year. High mean 8-day S100B value and persistent intracranial hypertension predict a poor outcome (GOS 1-3) after 1 year.

Randomized Controlled Trial
Continuous low dose diclofenac sodium infusion to control fever in neurosurgical critical care.
Aim of this randomized prospective clinical trial is to compare two methods of antipyretics and evaluate their efficacy in controlling fever during the acute phase of brain damage. ⋯ Low dose DCF infusion is a potential useful strategy for a successful control temperature better than intermittent NSAIDs dosing, minimizing potentially brain-damaging effects of fever.
