Electrographic seizures are frequent and associated with worse outcomes following traumatic brain injury (TBI). Despite this, the use of continuous electroencephalogram (cEEG) remains low. Our study describes cEEG usage and treatment dosing antiseizure medications (ASMs) in an international pediatric TBI population, hypothesizing that children monitored with cEEG have an increased rate of treatment ASMs because of electrographic seizure detection, compared with children who are not monitored with cEEG. ⋯ Children monitored with cEEG after TBI have an increased prescription of treatment ASMs and clinical and electrographic seizures. The increased rate of treatment ASMs in the cEEG group may indicate increased recognition of electrographic seizures.

Severe intracranial hypertension is strongly associated with mortality. Guidelines recommend medical management involving sedation, hyperosmotic agents, barbiturates, hypothermia, and surgical intervention. When these interventions are maximized or are contraindicated, refractory intracranial hypertension poses risk for herniation and death. We describe a novel intervention of verticalization for treating intracranial hypertension refractory to aggressive medical treatment. ⋯ Verticalization is an effective noninvasive intervention for lowering ICP in intracranial hypertension that is refractory to aggressive standard management and warrants further study.

Science continues to search for a neuroprotective drug therapy to improve outcomes after cardiac arrest (CA). The use of glibenclamide (GBC) has shown promise in preclinical studies, but its effects on neuroprognostication tools are not well understood. We aimed to investigate the effect of GBC on somatosensory evoked potential (SSEP) waveform recovery post CA and how this relates to the early prediction of functional outcome, with close attention to arousal and somatosensory recovery, in a rodent model of CA. ⋯ Glibenclamide improves coma recovery, arousal, and brainstem function after CA with decreased number of ischemic neurons in a rat model. GBC improves SSEP recovery post CA, with N10 amplitude reaching the baseline value by 120 min, suggesting early electrophysiologic recovery with this treatment. This medication warrants further exploration as a potential drug therapy to improve functional outcomes in patients after CA.
