Peritoneal dialysis in chronic renal failure.

The long-term results of intermittent peritoneal dialysis in long-term treatment of renal disease have yet to equal those of intermittent hemodialysis. However, further exploration and refinement of this technique is justified. Performed in acute stages of disease, both peritoneal dialysis and hemodialysis relieve the symptoms of uremia and specifically "buy time" for the patient so that proper medical or surgical therapy may be instituted. In acute situations, peritoneal dialysis is the procedure of choice, and is an important adjunct to more conventional treatment for chronic renal disease. It may be useful sometimes even in chronically hemodialyzed patients-for example, when the hemodialysis cannula for one reason or another is inaccessible because of clots, replacement, or infection. It is especially valuable when the hemorrhagic complications of uremia contraindicate hemodialysis treatment. Its use in chronic uremia remains sharply limited in time, but for brief periods chronic peritoneal dialysis appears to be a reasonably satisfactory means of prolonging life while awaiting homotransplant or decision for maintenance hemodialysis therapy.
