Abstract: Objective To explore the application effect of intraoperative autotransfusion in operation of orthopedics department. Methods Chose 62 cases of bone surgery from Mar. 2013toAug. 2014as research object ，divided them into observation group and control group according to the length oftail number of odd ，respectively 32cases and 30cases. The control group was treated with center suction for bleeding in operation field ，and the observation group was treated with intra operative auto transfusion. Results There were no statistical significance on Hct ，Hb and bleeding amount between observation group and control group before and after surgery （P > 0 . 05）；the allogeneic transfusion amount of observation group was obviously lower than that incontrol group （P < 0 . 05）；the allogeneic transfusion cases of observation group was obviously lower than that in control group （P <0 . 05）. Conclusion Application of intraoperative autotransfusion in orthopedic surgery， can effectively avoid or reduce allogeneic transfusion and the complications，it can be popularized in orthopedic department.
