The optical hematocrit method (CRIT-LINE) from In-Line Diagnostics, Ogden,
Utah, was used to follow blood volume during continuous hemofiltration or
continuous hemodialysis. With continuous hemofiltration, at a UF rate of 50-
200 ml/hr, BV did not change, and it was possible to set the UF rate
accordingly. Surprisingly, with similar UF rates, the authors report an
initial drop in BV with continuous or with "slow" hemodialysis, even at zero
UF rate. The reason for this is totally unclear, unless the dialysate sodium
level was unduly low. The explanation for these results is not apparent.
The abstract's importance is in the potential benefits from monitoring BV
continuously during CRRT.
