Table 2.
The comparison on preoperative hematocrit (Hct), postoperative Hct, total red blood loss (RBL), measured RBL and hidden RBC loss in experimental and control groups.
| Groups | Control group (n=54) | Experimental group (n=54) | t | P |
|---|---|---|---|---|
| PBV (mL) | 2480.0± 260.0 | 3080.0±310.0 | 10.90 | <0.001 |
| Total RBL(mL) | 265.4±28.5 | 437.4±33.9 | 28.54 | <0.001 |
| Measured RBL (mL) | 96.9±11.8 | 135.2±13.5 | 15.70 | <0.001 |
| Hidden RBL (mL) | 170.8±37.2 | 364.2±41.5 | 25.50 | <0.001 |
| Preoperative Hct (%) | 37.2±3.7 | 36.0±3.5 | 1.73 | 0.086 |
| Postoperative Hct (%) | 26.5±3.2 | 21.8±3.6 | 7.17 | <0.001 |
PBV – patient blood volume; RBL – red blood cell loss; Hct – hematocrit.
