The application of peritoneal dialysis for the therapy of electrolyte and acid base disorders

Abstract

Peritoneal dialysis (PD) is also found to be effective for the therapy of electrolyte and acid base disorders besides renal failure. Physiological saline solution was used as a main composition of a PD fluid in nine patients with metabolic alkalosis. PH and base excess of these patients were improved to the normal level. The fluid of lower Na concentration (Na=70mEq/L) was used for one patient with hypernatremia and the one of higher Na concentration (Na=190mEq/L) for two patients with hyponatremia. Serum Na in these three patients were corrected to the normal range. The fluid mixed with distilled water, 10%NaCl and 7%NaHCO₃ (HCO₃^-=34-68mEq/L) was effective for the treatment of lactic acidosis caused by shock in two patients.
