“…This is surprising because the impact of intradialytic ultrafiltration volume/ultrafiltration rate on the course of ⌬RBV is well-known. [11][12][13][14] Because the length of the interdialytic interval is a major determinant of fluid accumulation between hemodialysis sessions, most patients on a thrice-weekly hemodialysis schedule are more overhydrated at the start of the first than at the start of the second and third hemodialysis sessions of the week. Consequently, the prescribed ultrafiltration volume/ultrafiltration rate, in order to reach dry weight, is usually higher at the first than at the second and third hemodialysis sessions of the week.…”

Monitoring of relative blood volume changes (DeltaRBV) has been propagated for the prevention of hemodialysis hypotension. Although the influence of ultrafiltration volume on DeltaRBV is well-known, there is no mention in the literature that DeltaRBV results should be interpreted differently for the first, second, or third hemodialysis session of the week. To elucidate whether DeltaRBV and its derivative, DeltaRBV normalized for ultrafiltration volume (DeltaRBV/ultrafiltration ratio), vary systematically over the week, we separately analyzed these parameters for the first, second, and third hemodialysis session of the week in 13 chronic hemodialysis patients over a 17-week period. As expected, mean (+/-SD) ultrafiltration volume was significantly (p < 0.001) higher during the first session than during the second and third hemodialysis sessions (3163 +/- 615, 2622 +/- 674 and 2607 +/- 638 ml, respectively). DeltaRBV was significantly (p < 0.01) more negative at the first session than at the second and third hemodialysis sessions (-10.1 +/- 2.7, -9.3 +/- 3.0 and -9.3 +/- 3.1%, respectively). The DeltaRBV/ultrafiltration ratio was significantly (p < 0.01) less negative at the first session than at the second and third hemodialysis sessions (-3.2 +/- 0.6, -3.5 +/- 0.8 and -3.6 +/- 0.6%/l, respectively). In conclusion, DeltaRBV and the DeltaRBV/ultrafiltration ratio differ systematically between the first and other hemodialysis sessions in patients on a thrice-weekly hemodialysis schedule, most likely as a result of different ultrafiltration volumes.

“…In each HD patient, Hct monitoring was performed by using Crit-Line (JMS, Hiroshima, Japan) 10 throughout the HD session. The change in Hct can be measured continuously and noninvasively by an optical reflection method, with an optical monitor (950 nm) clipped onto the arterial blood line.…”

“…Several methods were developed for continuous and non-invasive measurement of BV changes. They all measure specific blood properties, such as electrical conductivitiy [32,33], optical density [34][35][36][37] or velocity of sound waves in blood [38,39]. All methods were proven to be reliable and to give an indication of hemoconcentration, which correlates with relative BV.…”

Despite substantial progress in blood purification techniques over the last three decades, treatment-related hypotensive episodes remain one of the major problems in hemodialysis therapy. There are two main reasons for hypotension occurring during dialysis treatments. First, hypovolemia is frequently induced by rapid fluid removal from the blood compartment which is in excess of refilling of fluids from the interstitial space. Second, many patients fail to support blood pressure by adequate vasoconstriction or increased heart rate as a response to hypovolemia. The capacity to respond adequately to volume contraction may be reduced due to patient- or treatment-related factors, among which heat accumulation within the body plays a major role. Recently, two newer technical developments became commercially available for use in hemodialysis therapy: devices for blood volume and blood temperature control were designed to reduce the incidence of intradialytic hypotension. Although blood volume and temperature measurements are easy to perform today, there is some uncertainty in the dialysis community how and when their use may be helpful and in which patients it is indicated. This review critically discusses the application of blood volume- and temperature-measuring devices with regard to their usefulness in the clinical setting.
