Abstract
During a 12-year period 419 patients were admitted because of acute renal failure requiring dialysis. Fifty (12%) had septicemia verified by blood culture. In a retrospective study age, sex, focus of infection, blood culture results, kidney function, mode of dialysis treatment, numbers and durations of complicating organ failures, presence of gastrointestinal bleeding, and secondary complicating events of septicemia were recorded for the purpose of establishing a prognostic index based on clinical criteria. Respiratory failure was present in 34 patients, circulatory failure in 31 patients, failure of coagulation system in 25 patients, and hepatic failure in 10 patients. Overall mortality was 46%. Highest death-rates were found during the first days of dialysis. In patients with multiple organ failures, in elderly and in patients suffering from staphylococcus aureus septicemia, a nonsignificant trend towards higher mortality was found. The mode of dialysis treatment did not influence patient survival. Our intention of establishing a prognostic index based on bedside clinical criteria has not been fulfilled. Even though mortality-rate increases in patients with acute renal failure complicated by failure of one or more vital organs, survival-rate in patients with four or more organ failures was 30%.
