[Effect of peritoneal dialysis on respiratory function in patients with chronic renal failure].

In 17 patients with end stage renal failure the effect was studied of a single peritoneal dialysis on the respiratory function, in the sitting and the recumbent position of the body. After the infusion of 2 liters of the dialysis fluid into the peritoneal cavity arterial PaO2 fell as well as the functional residual capacity, but the alveolar/arterial oxygenation difference (A-alpha)O2 rose. The most marked changes accompanied by dyspnea occurred in most patients in the sitting position. The inspiratory residual volume (IRV) increase reflects a better diaphragmatic function. The usefulness of aminophylline is discussed which not only dilates the bronchi but also improves the contractibility of the diaphragmatic muscle.
