@christine777, I am very sorry to hear about your son's complications. This is surely difficult for you to witness. I received dialysis treatment for around 9 weeks due to acute renal failure related to my liver disease. So I cannot really comment on the dialysis thing because I was dealing with too many liver issues at the time. But I will say that his labs might show elevated and non elevated liver function numbers, and that might account for the varying liver functioning information.
It sounds like your son was in critical need of care due to the internal bleeding. I am familiar with being in similar situation, where the immediate concern is treating most critical medical issue to keep one alive.the keeping patient alive. Then the other issues can be addressed. I encourage you to be in his room when his doctor makes his rounds; speaking to the attending nurse is good, but cannot answer your questions.
Has his nephrologist been consulted? This is where I would start because he/she will know your son's medical history. He/she should also be able to
answer your concerns about the fluid build up and the liver questions. The kidney and liver are both filtering systems for our bodies, and they work closely together.
I hope he is doing better today. Rosemary
