Rainbow, I don't know. A MELD of 30 is very high--would qualify him for a transplant, but don't know if he would be an acceptable candidate. If he's being transferred to home hospice, it means no treatment. A better diet and less stress may help him feel better.
Yes, and if he becomes uncomfortable with ascites, he can also be drained.
Rainbow, yes, having him drained (paracentesis) would help him breathe better. The fluid is probably pushing up against his lungs. Prayers that he will make it home where he can receive better care.
Once they go into a coma, the end is usually near. If he is in pain, perhaps it is best to let him go. I'm so sorry he was too ill to make the trip home.
