Fellow PD'ers... it looks as though there may be hope on the horizon. Take a look at the new AWAK system currently being trialed in the US and Singapore. The most recent version relies on tidal PD and works up to 4 times more efficiently than the current modalities. A big plus is that it works with just 750 ml total fluid (500 dwell with 250 tidal) so it should help with the big tummey issue. My nephrologist is following this closely and told me that if the intial results hold up in trials then it will be a huge improvement over current modalities. It should be available by 2011.
