Abstract:
ObjectiveTo investigate the effect of tertamethylpyrazine on perioperative humoral immune function in patients required for autologous blood transfusion.MethodsSixty ASA Ⅰ or Ⅱ patients aged 20-60 yr weighing 50-75 kg undergoing elective spinal surgery were randomly divided into 2 groups ( n =30 each):test group and control group.In test group,tertamethylpyrazine 2 mg/kg was infused intravenously over 5 min at 30 min before the autologous blood was collected.Tertamethylpyrazine was added to the heparinized saline and washing saline at the same time (25 mg per 500 ml) until the final concentration reached 0.005 ％.Tertamethylpyrazine was not given in control group.Venous blood samples were taken before anesthesia induction (T0) and at 1 h after operation (T1),and on day 1 and 5 after operation (T2.3) for measurement of serum IgG and IgM concentrations by ELISA.The operation time,intraoperative blood loss and amount of salvaged blood reinfused were recorded.ResultsThere was no significant difference in the operation time,intraoperative blood loss and amount of salvaged blood reinfused between the two groups (P ＞ 0.05).Compared with the baseline value at T0,serum IgG and IgM concentrations were significantly decreased at T1-3 in control group and the serum IgG concentration was significantly decreased at T1.2 in test group ( P ＜ 0.05 or 0.01 ).The serum IgG concentration at T2.3 and serum IgM concentration at T1-3 were significantly higher in test group than in control group ( P ＜ 0.05 or 0.01 ).ConclusionTertamethylpyrazine can reduce humoral immunosuppression to some extent and improve the balance of humoral immunity in patients required for autologous blood transfusion.
