From your description, your mother is indeed very unwell and she will need to be treated in hospital until she is stable. Low albumin
could be the result of the liver cirrhosis
or of the sepsis
(generalized infection). The oozing blood may also indicate that the blood is not clotting well, another sign of severe liver disease. Often patients who have an operation can have an exacerbation of their liver failure
because of the additional stress the body is under. The doctors can help her with antibiotics, blood products, tight control of her diabetes
and vigilant fluid balance monitoring. I sincerely hope that your mother has a complete and speedy recovery although this can take some time, even with the best modern treatment.
