Quality Of Hemodialysis Water And Dialysate In Hemodialysis Centers In Changsha

Object: To investigate the status of quality of hemodialysis water anddialysate in Hemodialysis Centers of Changsha.Method: A formal questionnaire was prepared and accounted in 20hospitals' Hemodialysis Centers in 2006 in Changsha. We had selectedfour points of hemodialysis water of water treatment system, which notonly acquired easily but also represent polluted situation: tap water,reverse osmosis water 1 (prepare B fluid sampling point), reverse osmosiswater 2 (go into dialysis machine sampling point), dialyser entrancedialysate sampling point, to detect endotoxin, free chlorine, hardness.Result:1 There are 6 disqualifications and 14 qualifications in endotoxin ofhemodialysis water and dialysate, all qualifications in free chlorine ofhemodialysis water and dialysate, 7 disqualifications and 13qualifications in hardness of dialysate for 20 hospitals HemodialysisCenters in 2006 in Changsha.2 In 20 Hemodialysis Centers there were 3 Hemodialysis Centers havingdouble osmosis system and 17 Hemodialysis Centers have one osmosissystems of water treatment system. There were 18 Hemodialysis Centers have water storage tank, 2 Hemodialysis Centers haven't. In aspect ofpreparation, there were 7 Hemodialysis Centers prepare A concentrationfluid prepare by themselves and 13 Hemodialysis Centers purchase drypowder, there were 6 Hemodialysis Centers prepare B concentration fluidprepare by themselves and 14 Hemodialysis Centers purchase drypowder.3 The levels of endotoxin in tap water was 166.005±11.71678 EU/ml, thelevels of endotoxin in reverse osmosis water 1 was0.19315±0.101083EU/ml, the levels of endotoxin in reverse osmosiswater 2 was 0.2191±0.1184EU/ml, the levels of endotoxin in dialyserentrance dialysate was 0.4284±0.22622EU/ml.4 There was significantly difference between double osmosis systems andone osmosis systems on endotoxin of hemodialysis water and dialysateof water treatment system (p＜0.01).5 There was significantly difference between after 2003 and before2003 put into production on endotoxin of hemodialysis water anddialysate of water treatment system (p＜0.01).6 There was significantly difference between no more than 3 years andsurpass 3 years change reverse osmosis membrane on endotoxin ofhemodialysis water and dialysate(p＜0.01).7 There was significantly difference between 3 months and surpass 3months disinfected reverse osmosis membrane on endotoxin of hemodialysis water and dialysate (p＜0.01).8 There was significantly difference between no more than 3 monthsand surpass 3 months disinfected pipeline on endotoxin of hemodialysiswater and dialysate (p＜0.01).9 There was significantly difference between nondead-spaceheat-sterilization of secondary circuit loop and no on endotoxin ofHemodialysis water in double osmosis systems(p＜0.05), there was alsosignificantly difference between water storage tank and no on endotoxinof Hemodialysis water and dialysate(p＜0.01).10 There was significantly difference between A and B concentrationfluid prepare on endotoxin of dialysate(p＜0.01).Conclusion:1 The sanitary quality of the dialysate in hospitals was associatedwith the using time of water system, the timely exchange anddisinfection of the water treatment system, and whether there were deepspace and water storage tank in the channel design,and A or Bconcentration fluid preparation.2 Double osmosis systems was superior to one osmosis systems inHemodialysis system of water treatment system.
