Abstract:

【Abstract】Objective To compare the cleanliness and failure rate between the dialysis machines with central dialysis fluid delivery (CDDS) system and the conventional dialysis machines, and to analyze the clinical application advantages of the dialysis machines with CDDS system. Methods From August 2017 to March 2018, the bacteria number and endotoxin level at the inlet and outlet sites were compared between the dialysis machines with CDDS system (5 sets) and the Berengdejia dialyzer (5 sets) in the PLA General Hospital Dialysis Center. A retrospective analysis was performed on the incidence of water, circuit and other faults occurred in the dialysis machines with CDDS system (18 sets) and the Berengdejia dialyzer (18 sets) during the period from March 2017 to March 2019. Results The bacteria number and endotoxin level at the inlet were lower in the dialysis machines with CDDS system than in the conventional dialysis machines (t=11.215 and 6.468 respectively; P＜0.001). The bacteria number and endotoxin level at the outlet were also lower in the dialysis machines with CDDS system than in the conventional dialysis machines (t=9.154 and 5.490 respectively; P＜0.001). The incidence of water, circuit and other faults were lower in the dialysis machines with CDDS system than in the conventional dialysis machines (t=9.147, P=0.010). Conclusion CDDS system can improve the cleanliness of dialysate and reduce the failure rate of dialysis machines during clinical applicati
