Lazarus Reflex on Physical Exam The Lazarus sign is a reflex movement observed in brain-dead or brainstem failure patients. It involves briefly raising the arms and dropping them on the chest, resembling the position of Egyptian mummies. The reflex is mediated by a spinal reflex arc and can occur after ventilator removal or during apnea testing. It is a rare occurrence and has been mistaken for resuscitation. Long-term survival after brain death diagnosis has been reported in some cases associated with the Lazarus sign. Recovery is not possible after brain death. #Lazarus #Reflex #PhysicalExam #clinical #video #neurology #criticalcare #braindeath #braindead
