[Continuous ambulatory peritoneal dialysis and respiratory pulmonary functions].

Acidobasic balance and respiratory pulmonary functions were examined in 15 patients with chronic renal insufficiency during continuous ambulatory peritoneal dialysis (CAPD) using a dialysis solution containing 1.5% or 2.5% of glucose. Patients did not suffer from any pulmonary disease nor ischemic heart disease. Biochemical indicators of acidobasic balance were in reference range or on its lower margin. Respiratory pulmonary functions were in tolerance except maximum expiratory flow volume at 50% and 25% of vital capacity (MEF50 and MEF25) and except diffusion lung capacity (DLCO) which were decreased. Decrease of maximum expiratory flow could be caused by a loss of elasticity of pulmonary parenchyma and by a beginning increased resistance in peripheral pulmonary ways. Decreased DLCO was identified in majority of patients and was caused by anaemia and a minimal interstitial pulmonary edema. Use of a single peritoneal dialysis with dialysis solutions of various glucose concentrations did not have any significant effect on acidobasic balance markers nor pulmonary respiratory functions.
