The aim of the study was to determine whether the Full Outline of UnResponsiveness (FOUR) score, which includes eyes opening (E), motor function (M), brainstem reflex (B), and respiratory pattern (R), can be used as an alternate method to the Glasgow Coma Scale (GCS) in predicting intensive care unit (ICU) mortality in traumatic brain injury (TBI) patients. ⋯ Having similar predictive power of mortality compared to the GCS and APACHE II, the FOUR score can be used as an alternative in the prediction of early mortality in TBI patients in the ICU.

Status epilepticus (SE) often does not respond to initial treatment. A second-line agent with a less established safety and efficacy profile is then required. This study examined the safety of intravenous (IV) lacosamide (LCM) in a critically ill population and obtained an estimate of effectiveness in patients with refractory SE on continuous video EEG monitoring (cEEG). ⋯ IV LCM appears safe short term in critically ill patients with SE. The retrospective estimate of effectiveness for LCM appears promising for management in SE. Prospective, randomized controlled studies are needed to better determine the role of LCM in treating SE.

Cerebral edema (CE) in traumatic brain injury (TBI) is the consequence of multiple underlying mechanisms and is associated with unfavorable outcomes. Genetic variability in these pathways likely explains some of the clinical heterogeneity observed in edema development. A role for sulfonylurea receptor-1 (Sur1) in CE is supported. However, there are no prior studies examining the effect of genetic variability in the Sur1 gene (ABCC8) on the development of CE. We hypothesize that ABCC8 single nucleotide polymorphisms (SNPs) are predictive of CE. ⋯ This is the first report assessing the impact of ABCC8 genetic variability on CE development in TBI. Minor allele ABCC8 SNP genotypes had increased risk of CE, while major SNP alleles were protective-potentially suggesting an evolutionary advantage. These findings could guide risk stratification, treatment responders, and the development of novel targeted or gene-based therapies against CE in TBI and other neurological disorders.

Current guidelines recommend routine clamping of external ventricular drains (EVD) for intrahospital transport (IHT). The aim of this project was to describe intracranial hemodynamic complications associated with routine EVD clamping for IHT in neurocritically ill cerebrovascular patients. ⋯ Routine clamping of EVD for IHT in cerebrovascular patients is associated with post-IHT ICP complications. Pre-IHT ICP ≥ 15 mmHg, increasing hourly CSF output, and IHT for therapeutic procedures are risk factors.

Comparative Study
Clevidipine Versus Nicardipine for Acute Blood Pressure Reduction in a Neuroscience Intensive Care Population.
Currently, a lack of published literature exists regarding the use of clevidipine in the neuroscience population. This agent may be preferred in some patients because of its short half-life, potentially leading to more narrow blood pressure (BP) control in comparison with other agents. The purpose of this study was to compare the difference in time to achieve target systolic blood pressure (SBP) goals with clevidipine versus nicardipine infusions in patients admitted to the neuroscience intensive care unit (NSICU) at our institution. ⋯ There were no statistically significant differences in acute BP management between the two agents; however, there was a trend toward shorter time to target and significantly less volume administered in the clevidipine group. Either agent should be considered a viable option in a NSICU population.
