Neurocritical care
-
The primary objectives of this study were to identify patient and community benefits of mandatory intensivist management in a neurocritical care (NCC) unit. Our hospital recently mandated intensivist management for patients admitted to the NCC unit. As one of the only comprehensive stroke centers in Orlando, an unacceptably high number of patients were being denied admission because of overcapacity. We compared length of stay (LOS), complications, outcomes, total admissions, and emergency transfer center closure rates before and after implementation of mandatory intensivist management. ⋯ Implementation of mandatory intensivist management in the NCC unit decreased LOS, increased admissions, and decreased service line closure rates, while maintaining patient care.

Randomized Controlled Trial
Pharmacokinetics and Pharmacodynamics of Tissue Plasminogen Activator Administered Through an External Ventricular Drain.
Intraventricular hemorrhage (IVH) frequently complicates spontaneous intracerebral or subarachnoid hemorrhage (SAH). Administration of intraventricular tissue plasminogen activator (TPA) accelerates blood clearance, but optimal dosing has not been clarified. Using a standardized TPA dose, we assessed peak cerebrospinal fluid (CSF) TPA concentrations, the rate at which TPA clears, and the relationship between TPA concentration and biological activity. ⋯ The pharmacokinetics of intraventricular TPA administration varies between individual patients. TPA dose does not need to exceed 2 mg. The optimal administration interval is every 8-12 h.

Traumatic Brain Injury (TBI) was chosen as an Emergency Neurological Life Support topic due to its frequency, the impact of early intervention on outcomes for patients with TBI, and the need for an organized approach to the care of such patients within the emergency setting. This protocol was designed to enumerate the practice steps that should be considered within the first critical hour of neurological injury.

There are many causes of acute myelopathy including multiple sclerosis, systemic disease (SD), and acute spinal cord compression (SCC). SCC should be among the first potential causes considered given the significant permanent loss of neurologic function commonly associated with SCC. ⋯ Bowel and bladder dysfunction and neck or back pain may also be part of the clinical presentation, but are not uniformly present. Because interventions are critically time-sensitive, the recognition and treatment of SCC was chosen as an ENLS protocol.

We previously reported the presence of a cranial "bruit" in patients with cerebral vasospasm by signal processing cranial accelerometry signals time locked to the cardiac cycle. This shift to higher frequencies is likely related to the turbulence of blood flow produced by vascular narrowing. We sought to build a more quantitative model to predict cerebral vasospasm then test the accuracy of this technique to detect cerebral vasospasm in a prospective blinded study. ⋯ Highly sensitive skull accelerometry can detect cerebral vasospasm with clinically meaningful accuracy. This tool holds promise in the ICU environment to detect as well as reject cerebral vasospasm as the cause of neurological deficits in subarachnoid hemorrhage.
