Although this classification is useful to categorize causes of membrane failure, several transport defects often coexist. The main causes of membrane failure include: Prolonged exposure to dialysis solutions, especially when hypertonic glucose is used; Acute peritonitis, as well as repeat or severe episodes of peritonitis

1. The two main properties of the peritoneal membrane are: a. Semi permeable – this allows substances of certain sizes to move from an area of greater concentration to less concentration. b. Bi Directional - substances move in either direction across the membrane. 2. So-called “lymphatic” drainage refers to bulk flow from the peritoneal ...

Membrane Permeability and Ultrafiltration – “slow transporters” the “tighter” the peritoneal membrane (higher mean glu) the slower will glucose diffuse out of the peritoneal cavity the osmotic gradient will be maintained longer the more ultrafiltration will take place

2011年1月21日 · As commonly used, the peritoneal equilibration test (PET) is the most familiar, consisting of a 4-hour dwell of 2.27% glucose dialysate, with a net ultrafiltration volume of less than 100 mL defining ultrafiltration failure. The alternative is the modified PET, which uses 3.86% glucose dialysate.

tissue surrounding the peritoneal cavity. • Trans-peritoneal transport is directly proportional to the area of peritoneum in contact with the solution. • Solute transport occurs via diffusion and convection across endothelia and through interstitial matrix. • Solute-free water transports from both blood capillaries and cells in peritoneal ...

• Mainly used in ovarian cancer with peritoneal metastases • The deadliest of all gynecological cancers • In 70 % it metastasizes throughout the peritoneal cavity • Intraperitoneal adminstration is pharmacokinetically advantegous due to the peritoneal to plasma barrier and delayed peritoneal clearance Padkumar S et al.

2013年1月19日 · There is a large body of experimental data that glucose and glucose degradation products trigger a cascade of events that lead to long-term peritoneal membrane damage. As is obvious, both the concentration of glucose and glucose degradation products are the highest in 4.25% dextrose solution.
