Sixty-five patients who remained in coma for more than 24 hours after resuscitation from cardiac arrest were divided into two groups according to their EEGs. Thirteen patients were found to have rhythm of alpha frequency while 52 had the usual EEG findings after cerebral anoxia. Three patients from the group with alpha frequency EEG rhythms regained full consciousness but showed severe sequelae. Our results suggest that the prognosis of comatose patients with EEG rhythm of alpha frequency is no poorer than that of other individuals who are comatose after cardiac arrest.
65名心脏骤停复苏后昏迷超过24小时的患者根据脑电图被分为两组。13名患者被发现有α频率节律,而52名患者在脑缺氧后有常见的脑电图表现。α频率脑电图节律组中的3名患者恢复了完全意识,但有严重后遗症。我们的结果表明,脑电图有α频率节律的昏迷患者的预后并不比心脏骤停后昏迷的其他患者差。
