title: [New diagnostic and therapeutic aspects of acute kidney failure].
abstract: In a 20 months' period 20 patients were dialyzed at the Cantonal Hospital, Lucerne, because of acute renal failure (ARF). Contrary to expectation, the main cause was not circulatory failure but traumatic and nontraumatic rhabdomyolysis (5 patients), septicemia (9 patients) and endogenous and exogenous intoxications. In only 2 patients did shock seem an important factor in the pathogenesis of ARF. In view of the many causes of rhabdomyolysis, the frequency of patients with myoglobinuric ARF is hardly surprising. Case history, brown-colored urine with a positive reaction for hemoglobin in the absence of significant hematuria and without significant hemolysis (as judged by the color of the plasma or serum) and, most important, high creatine kinase (10(4) to 10(6) U/l) point to the correct diagnosis. In patients who had undergone trauma or surgery the main cause of ARF was uncontrollable infection. A long interval between the accident or operation and the onset of ARF was typical in these cases. Both hemodialysis and peritoneal dialysis are adequate methods of treatment for ARF. For technical reasons, however, in more than 50% of patients with ARF due to trauma or surgery, peritoneal dialysis is not feasible. On the other hand, in patients with cardiovascular instability continuous arterio-venous hemofiltration serves as an alternative to hemodialysis. With the introduction of Y-shaped dialysis catheters and the single needle system with double pump and controlled ultrafiltration, hemodialysis has become an easier and safer procedure. For patients with prolonged-course ARF the authors prefer a combination of initial hemodialysis, followed by peritoneal dialysis.(ABSTRACT TRUNCATED AT 250 WORDS)
