These reports are fascinating and bizarre in equal measure, not least when you try and imagine what was happening in the room at the time.
Uncommon reflex automatisms after brain death
Rev Neurol (Paris). 1995 Oct;151(10):586-8.
Two cases of unusual complex movements observed in brain dead patients are described. Rapid and sustained flexion of the neck induced slow abduction of the arms with flexion of the elbows, wrists and fingers over 5 to 10 seconds. These movements have been rarely described and although they have similar clinical patterns, they are pathophysiologically different from the Lazarus sign which is observed few minutes after respiratory support cessation. While Lazarus sign is supposed to be due to an agonal discharge of anoxic spinal neurons, the movements described in this article result probably from complex reflexes generated in a disinhibited spinal cord. It is however surprising that they have never been described in patients with high cervical spinal injuries.
For those of you not familiar with the medical terms for movement, I shall briefly translate. When the doctors rocked the dead person’s head
side to side forward in a ‘rapid and sustained’ fashion, the body extended its arms to the side and waved them about.
I have two thoughts.
Firstly, isn’t it fascinating that such complex movements can be triggered solely by the spinal cord?
Secondly, what the bloody hell were they doing with that dead body?
Normally, these reports are of spontaneous movements in isolated brain dead patients, but on this occasion the medical team seem to have been rather more involved.
Unfortunately, the full text of the article is in French, so the exact turn of events (e.g. “hey looks what happens when I do this!”) shall have to remain a mystery.
UPDATE: Neuroshrink has added a fantastic correction and comment to this post that suggests what might have been happening and recounts his own experience of observing the Lazurus sign.
