Technical Considerations of Transcranial Doppler for the Assessment of Cerebral Circulatory Arrest: A US based National Survey

Without formal technical standards for transcranial doppler as an ancillary test for brain death, its generalizability and reproducibility as a diagnostic measure are limited. By understanding the current institutional standards for this test we may better understand where there is heterogeneity, why this is the case and how to guide future standards for its use. The objective is to survey neurosonology labs in the United States who perform transcranial doppler (TCD) for the evaluation of cerebral circulatory arrest (CCA) to better understand what standards are currently in place. Knowing this information could then ultimately create a basis for standardization and reproducibility.

Diagnostic, Therapeutic, and Prognostic Practices for Post-Anoxic Status Epilepticus: A Survey

Approximately 80% of cardiac arrest survivors fail to regain consciousness following return of spontaneous circulation (ROSC). (1) The hypoxic-ischemic brain damage that occurs due to decreased blood supply to the brain places these patients at an increased risk of seizures and status epilepticus (SE). (2) Post-anoxic status epilepticus (PASE) occurs in about one-third of comatose cardiac arrest survivors following ROSC. (3) Historically, PASE has been considered a marker of poor neurologic outcomes and high mortality. Recently, data has suggested that early aggressive treatment of PASE could improve chances of survival and neurologic recovery. (4,5) However, widespread therapeutic nihilism still exists regarding its treatment. In the majority of these patients, death occurs due to withdrawal of life sustaining therapies following pessimistic neurological prognostication. (5)

There are currently no standardized guidelines for the monitoring, diagnosis, prognostication or treatment of PASE. This leads to practice variability and limits our understanding of factors associated with favorable prognosis and outcomes of these patients. Our survey aims to characterize the heterogeneity in monitoring and diagnostic practices for patients with PASE. We also aim to capture the current beliefs regarding factors associated with good or poor prognosis, and the variability in treatment approaches.
