Clinical Study of Acute Hypervolemic Hemodilution on Meningioma Operation / 中国医师杂志

ABSTRACT

Objective To observe the clinical application of acute hypervolemic hemodilution (AHH) on patients undergoing surgical resection meningioma and the effects on the reduction of heterologous blood transfusion. Methods 40 scheduled mengingioma surgical patients were randomly divided into group I (AHH, n =20) and group II (control, n =20). All patients had same general anesthetic techniques. Amounts of heterologous blood transfusion and changes of postoperative hemoglobin in two group's were recorded and compared. Results BZ In AHH group 15 patients had no heterologous blood transfusion, 5 patients had 200～400 ml heterologous blood transfused. In control group all patients had 400～800ml heterologous blood transfused. Conclusion Acute hypervolemic hemodilution can significantly reduce the volumes of heterologous blood transfusion in mengingioma surgical patients.
