Comparison of relative blood volume changes in dialysis-symptomatic hypotension and dialysis-refractory hypertension during hemodialysis / 中华肾脏病杂志

ABSTRACT

Objective To investigate and compare relative blood volume (RBV) changes in dialysis-symptomatic hypotension and dialysis-refractory hypertension during hemodialysis. Methods Fifteen patients with dialysis-symptomatic hypotension (SH group) and thirteen patients with dialysis refractory hypertension (RH group) on chronic haemodialysis were enrolled in this study. RBV, blood pressure, heart rate and ultrafiltration volume (UV) were measured before hemodialysis and at 1 hour intervals during hemodialysis. Total of 149 and 146 five-hour hemodialysis sessions were performed separately. RBV was assessed using Automatic Blood Volume Monitor. Results RBV changes were significantly higher in SH group than in RH group (P
