Objective:To evaluate the clinical effect of intraoperative autotransfusion on postoperative hematoma of intracranial meningiomas and to expand the clinical application of blood callbacked in intracranial surgery.Methods:90 patients undergoing elective surgery for intracranial meningiomas were randomly allocated to the M group (the experiment group

n =60) and the C group (the control group

n =30).In the M group

the autologous blood retransfusion was given with the Haemonetics Cell-Caver5

and the blood gas analysis

Hb

Hct were observed before hemorrhage

after hemorrhage and retransfusion respectively.In the C group

the allogeneic blood transfusion was performed considering the intraoperative hemorrhage.All patients were followed up for volume of allogeneic blood transfusion

postoperative hematoma and postoperative infection.Results:The hemodynamics was steady.The Hb and Hct were maintained in the normal range during operation in both groups.The blood volume of postoperative allogeneic transfusion showed no significant difference between two groups.The incidence of the postoperative hematoma showed no significant difference between two groups

but the incidence of postoperative infection was lower in the M group than that of C group.Conclusion:Intraoperative autotransfusion could not influence the incidence of postoperative hematoma of intracranial meningiomas.With the perioperative management

the intraoperative autotransfusion can be used safely for intracranial surgery.
