My Mother Is In The Hospital For Liver Failure. She

My mother is in the hospital for liver failure. She has 90% damage to her liver. They are giving her Iv's to keep her potassium stabilized & she's on oxygen. Her levels for ALT were at 153 but dropped to 128. AST is at 144. Bilirubin is 24. Can there be a turnaround for her to get better & how long does it take to get the enzymes normal again? I don't think the doctors are doing anything to lower the enzymes
