Hello, Pickels, and welcome to the forum. I'm so sorry that your husband didn't stop drinking sooner. At this point, it may be too late. I do agree with Dany that he needs to be seen by a hepatologist. However, if Hospice is now involved, he will not receive any treatment and the NH may not even want to have a hepatologist see him. It does sound like he has bleeding varices. Banding is the usual treatment for that. Again, the "comfort measures only" decision may very well preclude doing that. I'm guessing you said one of his legs is amputated. What was the reason for that? There is much that could have been done if he had sought help sooner. Now it sounds like he is in really bad shape. He could well "bleed out" from the bleeding varices. So request a hepatology consult (one to come to him) and see what his recommendation is.
The purpose of the Lactulose is to rid his body (especially his brain) of ammonia. High ammonia levels will cause him to become agitated, confused, "totally out of it," may not recognize you or others, and even hostile. Nobody likes taking it, but the alternative is worse.
We have more caregivers, spouses, and family members here than we do patients, so you will receive a lot of support from them.
Hugs,
Connie
