Clinical relevance of marginal factors on ultrafiltration in peritoneal dialysis.

Background: Ultrafiltration (UF) in peritoneal dialysis (PD) is mainly driven by the osmotic gradient and peritoneal permeability, but other factors-such as intraperitoneal pressure (IPP)-also have an influence.

Methods: To assess the clinical relevance of these marginal factors, we studied 41 unselected PD patients undergoing two consecutive 2 h, 2.27% glucose exchanges, first with 2.

Long-term pneumoperitoneum in continuous ambulatory peritoneal dialysis (CAPD) caused by handling fault of Stay.Safe® system associated to bicaVera solution.

We found chronic pneumoperitoneum in two continuous ambulatory peritoneal dialysis patients from two different hospitals. Both patients used the Stay.Safe® system and bicaVera solution, whose extension tubing is not primed with fluid but air-filled, unlike that of the conventional solution bags.
