- Abstract:
- Objective To explore the effect of intraoperative autotransfusion on coagulation function in the scoliosis of preschoolers.Methods A total of 50 pediatrics patients undergoing scoliosis surgery were enrolled and divided into 3 groups according to the percentage of blooding volume and estimated blood volume(EBV):group A(<20%),group B(20-30%) and group C(>30%).Thromboela-stogram(TEG) was performed before operation,before and after autologous blood transfusion.Postoperative blood coagulation function was observed in each group.Results Significant differences existed in TEG indicators preoperative and pre-autologous transfusion(P<0.05).Similarly,significant differences also existed between preoperative TEG indicators and post-autologous transfusion(P<0.05).However,no difference was found in TEG indicators before and after blood transfusion.Amount of blood loss,but not autologous blood transfusions affected coagulation function.R and K values were prolonged with greater amount of blood loss while the other indicators decreased.No significant difference in TEG between preoperative and postoperative in group A.In groups B and C,R and K values significantly increased after transfusion while MA and α declined markedly(P<0.05).Conclusion There is no damage of coagulation function in patients with blood loss volume ≤ 20% after autologous blood transfusion.However,when blood loss is >20%,postoperative coagulation dysfunction should be considered.Coagulation factors,platelets and fibrinogen should be supplemented promptly according to the relevant examinations.
