So, to me, it looks like the family is going to have to file an appeal to a higher court, before Dec 30. Sad that the family is going thru so much struggle for such a hopeless case. From what i understand, being brain dead, with no blood flow to the brain, her brain will begin to deteriorate (the sources I read said "decompse").
Another source also said that since her brain is dead, that there is no way that she could process anything her family says because you need brain function to turn sounds into meaningful words.
If any of our medically knowledgeable people here know, can you answer any of the following questions? I have tried to find answers but there is so much to read and most of it does not focus on these questions.
Jahi's family reported that her shoulder moved. Is this even possible? I don't think her body is capable of any voluntary movement but are there any involuntary body process that could account for this?
Also, in addition to the above question.. Could this reported shoulder movement simply be the body beginning to contract, as we often see brain damaged, persistent vegetative patients do? Will this happen to her?
What is the longest that anyone has lived on life support while brain dead and do you know the circumstances why they were kept that way for so long. I understand the cases where pregnant women were kept alive, but they were allowed to be removed from life support after the birth. Are there any other stories of long term life support after brain death?
Being brain dead, are her eyes fixed and dilated, not responding to light or movement at all?
Jahi's mother reported that her blood pressure went up when she listened to music (or when her mom talked, i forget which). I was under the impression that the ability to regulate blood pressure was in the brain (the lower part, I think) so is it even possible that her blood pressure or heartbeat could respond to voices or music. Would they respond to painful stimuli or does she not even have the ability to process pain?
To continue her life support long term, what interventions will be needed. Ventilation and nutrition, of course but what else? Drugs to regulate blood pressure? What other meds or assistance.
If on long term support with nutrition, obviously her body would create waste products from that nutrition (urine, feces). It seems obvious she will be on a catheter but what will occur with her bowel process? Can her body/muscles even produce a bowel movement or would they have to intervene to remove such products from her body?
Sorry to ask so many questions. I just really want a clear understanding of all of this because i do intend on having conversations with family and friends about it. Thanks to our medical experts, you info has been very educational and helpful in understanding all of this.
Just want to address one more thing as I head for bed. Lower spinal cord reflexes can remain intact in brain dead people.
For example, a brain dead person can still manifest a serious BP syndrome like autonomic dysreflexia during the procurement procedure for organs, just as spinal cord injured patients do when exposed to certain bodily stimuli. There is an unregulated flood of endogenous catecholamines (epinephrine, etc) in response to certain stimuli (full bladder or bowel stimuli are examples in spinal cord injured patients). For this reason, paralytic drugs and inhalational anesthetic agents, and sometimes narcotics, are administered to brain dead donors during the procurement surgery, to attenuate these responses. Endogenous catecholamines and lower spinal cord reflexes are independent of brain stem and cerebral function.

There are no clear recommendations regarding perioperative
management of the brain-dead organ donor
outside of administering neuromuscular blocking agents
to prevent spinal reflexes or movements in response to
surgical stimulation, fluid resuscitation, and maintenance
of certain hemodynamic values.16-18 The same intact
spinal cord that exhibits spinal reflexes to noxious
stimuli is also capable of inducing the release of catecholamines
through the adrenergic loop.2,8,19-22 Many researchers
compare this sympathetic catecholamine surge
in organ donors to that which occurs in autonomic hyperreflexia
in the living patient with a previous spinal cord injury. This is a well-documented phenomenon that can occur with noxious stimuli of any type. The uncontrolled sympathetic outflow can cause deleterious effects
to body systems if it is not treated.23
