MO665THE BRAND-NEW NEEDLE CAP ELIMINATES ALL VISIBLE AIR BUBBLES DURING THE AUTOMATIC PRIMING PROCESS OF HEMODIALYSIS MACHINES

Abstract Background and Aims The air contamination from the dialysis circuit into patient's body is an unsolved serious problem. Recently, Automatic priming function of machines widely used. There are rarely any bubbles left in extracorporeal after automatic machines. To use this method, arterial venous sides connected to create a closed so that dialysate can circulate overflowed through line circuit. However, may enter when disconnecting attaching needles. We tried solve problem by simply connecting needles before process process. prime whole with needles, we had made brand-new suitable cap needle, which tightly needle has open end. (Fig) This special allows be incorporated prior process, allowing machine completely remove during purpose study present details new method compare its effectiveness preventing bubble between traditional method. Method A prospective, non-randomized, comparative was conducted verify whether remained grossly visible method: DCS-100NX (Nikkiso Co Ltd, Tokyo Japan) used for priming. After finished. Nurses disconnect side connect both ends hands. nurse operates blow small amount out air. It takes nearly 2minutes each case. examined circuits consecutively. New cap-based were auto-primed N100. priming, including performed In thoroughly checked remaining macro naked eye. Since on likely supplemented trap chamber, only compared. Results October 15th 24th 2020 at Yokohama Minami Clinic. 50 29 times times. 10 consecutive performed. as machine. no eye Statistical statistically significant difference count (p=0.0001, Pearson's chi-square test) Conclusion All removed automatically using easy-to-use highly effective could considered essential device hemodialysis treatment like seat belts automobiles.
