Q: What can we do once a patient has been diagnosed as being in a persistent vegetative state?
A: Three choices are possible: Provide aggressive medical treatment to keep the patient alive. Doctors will work to remove the mechanical ventilator, surgically implant a aracheostomy tube in the patient’s throat to protect him/her against choking and start medical nutrition (through a tube). If the patient survives, he or she will be transferred, when stable, to a long-term nursing care facility.
Try the above treatment plan for a specific time with the understanding that if no signs of recovery occurs, either some or all treatment will be stopped. Patients without any artificial treatment, including tubal feeding and fluids, usually die within 1-2 weeks.
Withdrawing artificial life-support immediately, including the breathing machine and medical nutrition (food) and fluids will allow the patient to die without discomfort. Since that part of the brain that no longer sends messages telling the brain to be aware of and experience pain, the patient will die without discomfort, usually within 2 weeks.
