The investigation of standard deviation of Kt/V(δKt/V)as an important indicator for the evaluation of general clinical conditions of chronic maintenance hemodialysis patients

Objective To understand the relationship between standard deviation of Kt/V(δKt/V) and the blood pressure、serum albumin concentration of chronic maintenance hemodialysis patients and to investigate the role of δKt/V in evaluating the general clinical conditions of the hemodialysis patients. Methods The blood pressure were observed 2 hs after the beginning of one hemodialysis session and δKt/V were calculated. The relationship of δKt/V and the systolic blood pressure (SBP) diastolic blood pressure (DBP) and mean blood pressure (MBP) were analyzed.Results There was a significant positive correlation between the SBP,DBp and MBp change and the range of δKt/V (r1=0.400, P0.01; r2=0.255, P0.05; r3=0.367; P0.01 respectively). The blood pressure control closely depended on the quality of hemodialysis therapy. There was a significant negative correlation (r=-0.690,P0.05)between δKt/V and the serum albumin concentration in chronic maintenance hemodialysis patients. Conclusion The δKt/V range of the chronic maintenance hemodialysis patients is a valuable index for the hemodialysis quality. δKt/V can be an important indicator for the evaluation of the general clinical conditions of the chronic maintenance hemodialysis patients.
