My husband is a liver patient. He is on the list and has been called four times. Unfortunately, he has been unable to get a good one. From April 7 to October 7 he was in the hospital. He had to have surgery due to a small bowel obstruction which was most likely brought on by his double hernia operation. He is home now, but all day has been throwing up. He is confused a little and I am concerned because he does get encephaloptic. I am worried he has another sbo. Is this possible and how will I know when I should call the ambulance? I am afraid to go to sleep this evening as he might not be responsive in the am. He has been in the hospital 3 times this month already for high ammonia levels.
