[The Lazarus phenomenon]

The pathophysiological mechanisms of auto resuscitation - also called the Lazarus phenomenon - are unknown, but they are thought to be related to matters such as hyperkalaemia, hyperventilation and alkalosis or increased end-expiratory pressure during assisted ventilation. The phenomenon is probably underreported and this case report of the Lazarus phenomenon in a patient with severe hyperkalaemia demonstrates the necessity of following recommendations regarding resuscitation such as allowing pauses in assisted ventilation as well as ten minutes post resuscitation monitoring before declaring the patient dead.
