Comparison of VBL, HBL and TBL between two groups. P values indicate that VBL of PPSF group is significantly less than that in the MWPSF group. (P < 0.01) And the HBL and TBL of the PPSF group are significantly higher than that in the MWPSF group (P < 0.05). Abbreviation: VBL, visible blood loss; HBL, hidden blood loss; TBL, total blood loss
