Cell salvage volumes
There were no significant differences between study groups in total fluid volume collected in BCR, ATBR, incubation time, waste fluid and washing fluid. Although the volume of WRBC was higher in the citrate group this difference was not significant. The significant difference in Ht in WRBC between groups (see Table No significant differences were noted in fluid volume or type, administered before, during and after cardiopulmonary bypass. Intraoperative diuresis was not significantly different between the groups. The total heparin dose during cardiopulmonary bypass was not significantly different between the groups (Citrate group: mean heparin dose: 32,361 (11,776) IU, heparin group: 36,711 (13,087),
