Hi my father is 78 years old and having ckd and bp from 6+ years and on medication .his creat stays in between 4 to 5 and electrolytes and urine output is fine. 2 +  year ago he had sizzure like instance but after stopping sizure medicine due to side effects no issue till now. But last night suddenly he again started same sizzure like issue and vomiting.he is stable now but creat is raised i.e 9 and urine output is fine. So what is reason for the same and what will be next course of action? Please guide if urgent dialysis needed or vomiting and sizzure can be treated first and then creat raised.
