[Comparison of various pharmacologic and conventional methods of increasing the effectiveness of peritoneal dialysis. V. Usefulness of selected parameters of peritoneal transfer for evaluating the effectiveness of intermittent peritoneal dialysis].

On the basis of analysis of peritoneal transfer parameters in intermittent++ peritoneal dialysis it was shown that 1) dialysate/plasma ratio is a good parameter for comparison of efficiency of peritoneal dialyses performed using different schedule only when dialysis fluid flow rate is unchanged; 2) dialysis-induced ultrafiltration markedly influences peritoneal transfer parameters of sodium; 3) when the influence of residual dialysis fluid on peritoneal transfer parameters is excluded, peritoneal clearance is very useful in comparison of efficiency of peritoneal dialyses performed using different dialysis schedule, but if dialysis schedule is changed during the course of dialysis, the determination of clearance value in each exchange is advisable because dialysis schedule used in one dialysis period can influence clearance value in following exchanges performed in different manner; 4) concentration of low-molecular-weight substances in dialysate after intraperitoneal administration of pharmacological agent if does not decrease in the course of dialysis may indicate on enhancing effect of this agent on peritoneal transfer.
