I don't think you read my reply. Okay, let me add to it for more clarification. No one's feeding tube should be removed, nor any other source of hydration and nourishment, until the person dies. No one should be allowed to remove a patient's feeding tube, period. Like I said, I am not referring to heart/lung machines, ventilators, or anything else that does the work that an organ should be doing.
Oh, and Robert? I would make sure that not only did your feeding tube stay in place, you would receive all the therapy possible to improve your condition. Your friends, family, and clergy would be welcome to visit you any time they wanted to. You'd enjoy fresh air, tv, music, and pictures on the walls. Robert, you may be a pain in the ass, but you're a living human being who deserves to be treated with respect :)
Even if it's in writing?
Well, I disagree.
I wouldn't go that far. If someone's feeding tube becomes clogged or infected, it would be entirely proper to remove it (and replace it). And if someone starts eating well enough without a tube as to render it unnecessary, I'd see nothing wrong with removing it so as to avoid any possibility of future infection.
