Measurement of hemodialysis (HD) access flow (Q A) is a noninvasive approach for arteriovenous graft or fistula surveillance. Flow dilution (FD) and in-line dialysance (DD) are two common methods for measuring Q A. In a randomized fashion, we prospectively evaluated Q A using FD and DD in 48 HD patients during three separate HD sessions over a span of 3 months. The measurement of Q A was similar (1,016±412 ml/min for FD and 1,009±425 ml/min for DD, p= 0.44 and 0.79 for the mean and standard deviation, respectively). While FD successfully measured Q A≥ 2,000 ml/min, DD “saturated”(indicating a Q A≥ 2,000 ml/min without providing a numerical Q A value)(n= 17). The correlation coefficient for Q A≤ 2,000 ml/min between DD and FD measurements from the same dialysis sessions was high (r= 0.9, p< 0.001) with a straight line slope of 0.997. Access flow values for FD and DD methods were comparable at Q A≤ 2,000 ml/min and no single method tended to over-or underestimate Q A compared with the other. For Q A> 2,000 ml/min, FD provided a quantitative Q A measure, and is therefore a potentially useful tool for Q A above this threshold, while DD is not.
