Hospital-based use of therapeutic hypothermia after cardiac arrest in adults.

Improving survival and brain function after initial resuscitation from cardiac arrest remains a critical challenge with few therapeutic options. The publication of several randomized controlled trials supporting the use of therapeutic hypothermia in cardiac arrest survivors has provided a remarkable opportunity to reduce mortality and neurologic disability from this leading cause of death. On the strength of these trials, therapeutic hypothermia has now been incorporated in the American Heart Association guidelines for post-resuscitation care. This review will focus on the hospital-based application of therapeutic hypothermia in adult cardiac arrest survivors, with special attention to practical aspects of cooling, protocol development, and evaluation of recent data from "real world" experiences using hypothermia as a treatment option. Finally, remaining research questions and directions for future improvements in therapy will be discussed.
