  • Summary

    This chapter uses a case-based approach to describe electrographic patterns associated with coma. These are rare and, though non-specific, may suggest particular underlying etiologies. The electrographic pattern of extreme delta brush (EDB) may be seen with anti-NMDA receptor encephalitis. Alpha-coma is a pattern of continuous unreactive alpha or alpha-theta range activity that may be seen in coma after cardiac arrest or in those with pontine injury. It may resemble normal wakefulness. Spindle-coma and beta-coma are also described. Electrocerebral inactivity (ECI) is the absence of all non-artifactual electrical activity on an EEG, when recording using minimal specified technical standards in patients with cerebral death (brain death).

  • Anoxic brain injury is a common outcome after cardiac arrest. Despite substantial research into the pathophysiology and management of this injury, a beneficial treatment modality has not been previously identified. Recent studies show that induced hypothermia reduces mortality and improves neurological outcomes in patients resuscitated from ventricular fibrillation. This article reviews the literature on induced hypothermia for anoxic brain injury and summarizes a treatment algorithm proposed by the Canadian Association of Emergency Physicians Critical Care Committee for hypothermia induction in cardiac arrest survivors.
