Clinical Analysis on Segment-ultrafiltration Hemodialysis in Preventing and Treating the Patients with Intradialysis Hypotension

Objective To compare and evaluate the incidence of intradialysis hypotension(IH) in both segment-ulrafiltration hemodialysis and standard hemodialysis.Methods 22 hemodialysis patients underwent standard dialysis and segment-ultrafiltration hemodialysis for one month respectively.Blood pressure and weight of IH were measured during the dialysis session.The frequency of hypotension was also recorded.Results As compared with standard hemodialysis,the incidence of hypotension during dialysis was significantly decreased in segment-ultrafiltration hemodialysis(P0.05).There was no statistical significance on biochemical indicators and total ultrafiltration volume between standard hemodialysis and segment-ultrafiltration hemodialysis(P0.05).Conclusion Blood volume is better preserved and the incidence of hypotension is significantly decreased in segment-ultrafiltration hemodialysis.
