Nutritional management of the adult patient undergoing peritoneal dialysis.

Until the last few years, maintenance peritoneal dialysis (PD) often was associated with progressive wasting due to frequent episodes of peritonitis, loss of considerable amounts of protein into the dialysate, and poor nutritional intake. Recently, available techniques have made PD a feasible alternative for the long-term care of the patient with end-stage renal failure. The incidence of peritonitis has been markedly reduced, and protein loss is only 4 to 20 gm. per dialysis treatment. Preliminary studies have shown no differences in the nutritional status of patients undergoing PD or hemodialysis, although both groups have evidenced malnutrition. In the patient undergoing PD, daily intakes of 1.2 to 1.5 gm. protein and 35 kcal per kilogram body weight are recommended. During times of stress, parenteral administration of nutrients may be necessary. Dietary supplements may often be required chronically. Careful studies are needed to difine the nutritional needs of the patient undergoing PD.
