Continuous flow (CFPD) and intermittent (IPD) peritoneal dialysis were compared in pigs, using a double lumen silicone rubber peritoneal dialysis catheter. For CFPD, after instillation of 30 ml/kg into the peritoneal cavity, dialysate was continually infused and drained at approximately 25 ml/kg/h. A dwell volume of 30 ml/kg was also used for IPD. Similar length cycles of each technique were compared in Experiment 1. In Experiment 2 total solute clearance and ultrafiltration achieved over two consecutive IPD cycles were compared with CFPD of a similar duration. The catheter functioned well with few complications. In Experiment 1, CFPD produced greater ultrafiltration and significantly improved the clearance of urea, potassium and phosphate compared to IPD. No significant difference between the techniques was observed in Experiment 2. Our data suggest that for CFPD to retain its advantage over IPD intermittent complete drainage of the peritoneal cavity may be necessary.

D012826 Silicone Elastomers Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants. Elastomers, Silicone,Rubber Silicone,Silicone Rubber,Elastosil,Microfil,SE-30,Elastosils,Microfils,SE 30,SE30,Silicone Elastomer
