Implementation of Therapeutic Hypothermia After Cardiac Arrest in the Intensive Care Unit

Sudden cardiac death is the most common cause of death in the United States. Despite aggressive resuscitation, only one tenth to one third of successfully resuscitated patients survive to lead an independent life. Although evidence clearly supports the use of induced therapeutic hypothermia post–cardiac arrest, the precise data on how to best implement this process is still forthcoming. Protocol-based treatment regimens have been shown to improve morbidity and mortality of patients with common ICU illnesses. This article discusses the multiple elements compromising therapeutic hypothermia and presents recommendations for a protocol-driven regimen that can be implemented across varied critical care settings.
