Methods One hundred and nine patients with preserved autologous blood transfusion in general surgery and orthopedic patients undergoing elective surgery were enrolled in this study. Three groups of patients with autologous whole blood collected from preoperative autologous erythrocytes and non-autologous blood were collected and analyzed. The changes of Hb, Hct, Plt on the 1st and 3rd postoperative day, and the rate of allogeneic blood transfusion, postoperative average length of stay and so on were evaluated to evaluate the effectiveness of prefilled autologous blood transfusion. Results Hb was significantly higher in patients with autologous component blood 1 day and 3 days after operation (117.66 ± 18.02 g / L vs 118.4 ± 16.79 g / L vs. 143.6 ± 10.96 g / L, P <0.05, respectively) ± 4.63% vs 36.24 ± 4.85% vs 43.17 ± 3.15%, P <0.05; Plt (201.29 ± 58.09) × 109 / L vs. (202.28 ± 48.06) × 109 / L vs. (240.11 ± 72.29) × 109 / L, P <0.05, respectively. Compared with preoperative, the level of Hb (139.43 ± 12.11) g / L vs. (114.93 ± 15.87) g / L vs. (112.72 ± 17.9) g / L, P <0.05; Hct (42.45 ± 3.08)% vs (35.73 ± 4.3)% vs (34.08 ± 5.44)%, P <0.05; (P <0.05). Compared with preoperative Hb (117.7 ± 0.05), P < (P <0.05); Hct (35.33 ± 5.26)% vs (33.73 ± 5.42)% vs (42.33 ± 0.62) g / L vs. (112.62 ± 18.2) g / L vs. (139.97 ± 11.12) g / P <0.05); Plt (166.27 ± 57.74) × 109 / L vs. (154.08 ± 55.75) × 109 / L vs. (216.13 ± 82.21) × 109 / L, P <0.05) Patients postoperative Hb> 110 g / L, Hct ≥ 33%. There was no significant difference in the Hb and Hct changes between the three groups at 1 and 3 days after operation (P> 0.05), while Plt at 1 d and 3 d after operation in autologous blood group and autologous whole blood group was higher than that in control group (P <0.05) ). Compared with the control group, the self-component blood group and the control group effectively shortened the average length of stay (17.93 ± 7.13) d and (13.09 ± 5.58) days, respectively, P <0.05. There was no significant difference between the autologous blood group and the control group (13.09 ± 5.58) d, (14.39 ± 5.13) d, P> 0.05. There was no significant difference in allogeneic blood transfusion rate between autologous blood group and autologous whole blood group (11.4%, 22.7%, P> 0.05). Conclusion It is feasible and safe to use the technique of component apheresis for blood transfusions of autologous components in order to shorten the average length of hospital stay and reduce the rate of allogeneic blood transfusion.
