APD prescription: Achieving the adequacy goals

In the last few years, automated peritoneal dialysis (APD) has undergone considerable improvements due to technological developments. The definition of a minimal dose of peritoneal dialysis (PD) has not yet been completely assessed. Appropriate use of APD requires an evaluation of dialytic efficiency in terms of dialytic indexes and their targets. Many dialytic treatment modalities have been performed in order to achieve adequacy targets. Some aspects have to be taken into consideration to reach the optimal dialytic dose: optimizing mass transfer in correlation with intraperitoneal volumes, prescribing tailored treatment modalities according to different characteristics of peritoneal membranes and individual patient needs, and performing more biocompatible treatments using different glucose pro ling and alternative physiologic PD fluids. New high-flow techniques such as continuous flow PD can ensure better urea and creatinine clearances and ultrafiltration rates, leading to a higher utilization of the APD modality.
