Abstract:
Objective To investigate the effect of acute normovolemic hemodilution on immune function by observing the level change of lymphocyte subsets in maternity sera.Methods 60 ASA I ～ Ⅱ parturients were divided into 2 groups,30 cases in each group.Parturients of group A received acute normovolemic hemodilution and parturients of group C received allogeneic blood transfusion.Blood pressure,heart rate,duration of the cesarean section and blood loss were observed.2mL blood samples were taken from the mothers'vein before the surgery,1 day after the surgery,5 days after the surgery.Flow cytometry was used to measure T lymphocyte subsets.Results The levels of CD3+,CD4+,CD8+,CD4+/CDs+ before the surgery had no statistically significant differences between two groups (P ＞ 0.05).The levels of CD3+ [(52.35 ±5.62)％,(48.44±6.45)％],CD4+ [(36.90±7.93)％,(32.05 ± 8.94)％],CD4+/CD8+ [(1.15 ± 0.26),(0.97 ± 0.22)] were much lower 1 day after the surgery than those of preoperation [CD3+:(59.67 ± 3.45) ％,(60.58 ± 4.27) ％ ; CD4+:(43.71 ± 8.45) ％,(43.21 ± 8.45) ％ ; CD4+/CDs+:(1.41 ±0.38),(1.45 ±0.48)] in both two groups(t =6.10,2.50;3.22,4.97;3.09,4.98;P ＜0.05).In group A,the levels of CD3+,CD4+,CD4+/CD8+ [(58.78 ± 5.24) ％,(43.18 ± 8.48) ％,(1.41 ± 0.41)] had no statistical differences 5 days after the surgery(P ＞ 0.05) compared with those of preoperation.While in group C,the levels of CD3+ [(57.11 ± 6.81) ％],CD4+ [(38.68 ± 7.70) ％],CD4+/CDs+ [(1.19 ± 0.37)] were lower than the levels before the surgery[(60.58 ± 4.27) ％,(43.21 ± 8.45) ％,(1.45 ± 0.48)],and of the differences were statistically significant (t =2.46,2.17,2.35 ;P ＜ 0.05).Conclusion Compared with allegeic transfusion,acute normovolemic hemodilution could benefit the recovery of parturients by alleviate the inhibitory effect of transfusion on the immune function.
