Standards for accurate in vitro characterization of dialyzers: test case the Vivacell.

A standard format is proposed for cataloging dialyzer transport data in order to improve communication and understanding of published results. The need for such a format is obvious from the ambiguity and lack of uniformity in published data. This report for in vitro characterization also describes an adequate experimental set-up for proper dialyzer characterization and an improved means for reporting uncertainty where curve fitting techniques are employed. The Vivacell dialyzer has been evaluated by these means as the first test case.

Hyper/hypo-osmotic peritoneal dialysis.

This report concerns the augmentation of peritoneal dialysis using alternating hyper/hypoosmotic peritoneal dialysates, and covers a detailed examination of the longest lived, anephric goat to be maintained using this delivery system. Experimental results show that with this technique: 1) urea clearance can be increased some 200% over control values, 2) the convective transport of urea is unimportant and the increased urea clearance is due primarily to increased peritoneal permeability, 3) net ultrafiltration and electrolyte balance can be easily controlled by variation of total electrolyte and glucose about an appropriate mean. A detailed autopsy failed to demonstrate any gross or microscopic pathology.
