[Influence of modeling sodium on the dialysis disequilibrium syndrome in hemodialysis].

OBJECTIVE: To observe the influence of modeling sodium on the dialysis disequilibrium syndrome in hemodialysis. METHODS: Sixteen patients received hemodialysis for the first time. Eight of them received the hemodialysis in the order of common sodium, modeling sodium, common sodium, and modeling sodium, whereas the other 8 patients were treated in the order of modeling sodium, common sodium, modeling sodium, and common sodium. The symptoms of the dialysis disequilibrium syndrome were observed and blood sodium concentration was examined before and after the dialysis. RESULTS: The main symptoms of the dialysis disequilibrium syndrome were headache, nausea, vomiting, hypertension, and dyspnea. Modeling sodium hemodialysis could significantly decrease the occurrence of these symptoms (P < 0.05). The blood sodium concentration after the hemodialysis was not significantly changed compared with that before the hemodialysis (P > 0.05). CONCLUSION: Modeling sodium hemodialysis can effectively prevent the occurrence of the dialysis disequilibrium syndrome without increasing the natrium load of the patients.
