So dad's gallbladder surgery went well; however, today (a day later) he's dehydrated and has low blood volume. His CBC prior had been high, though they're giving him transfusions, so I'm guessing it's not just water. They thought he had some sort of hemolytic infection, and I guess that's what it is. He's kinda disheartened, because he keeps getting blood infections, and this crap keeps happening to him. His immune system seems so weak the last year or two, though I know he has trouble sleeping.
