Analysis of clinical experience with a new twist lock connectology.
The DextroLyte II (Dex II) Peritoneal Dialysis System was designed to improve safety and convenience in dialysis therapy. Connectors introduced with this system have a threaded recessed male connector with a corresponding female counterpart. Products are provided for CAPD, Single Use Y, Long Life Y and CCPD. Safety and convenience features intended to reduce peritonitis rates and improve patient acceptance include the following: 1. Connectors with threaded male and corresponding female counterparts which provide a dual seal 2. Easy-to-break frangible which seals the solution bag until ready for use 3. A flange on the connector ensures proper hand placement by providing a safety shield to prevent contamination during connection 4. A hinged shield containing an impregnated povidone-iodine sponge easily snaps around the bag connector 5. A Quick Disconnect Clamp (QDC) provides external occlusion permitting safe disconnection for bagless techniques without opening the system 6. A standard medication port provides easy access for administration of intraperitoneal medication Results of a multicenter study performed in nine centers are as follows: Total patient participants 121 Total patient months 1207 Overall peritonitis rate 1 episode in 43 patient months We conclude that the Dex II peritoneal dialysis systems provide safe dialysis therapy as evidenced by the exceptional peritonitis rates. Patient acceptance has been excellent due to the inclusion of the safety and convenience features described.
