Hidden blood loss in perioperative period of femoral intertrochanteric fractures treated with Gamma nail and dynamic hip crews

Objective To analyze the hidden blood loss in perioperative period of femoral intertrochanteric fractures treated with Gamma nail and dynamic hips crew to enhance the clinical realization of hidden blood loss.Methods A re-trospective analysis of the 38 elderly patients with intertrochanteric fracture treated with Gamma nail and 32 elderly patients with intertrochanteric fracture treated with dynamic hip crews was taken to compare the mean operative time,intraoperative and postoperative blood loss,blood transfusion,the dominant and hidden blood loss.Results The mean operative time was(60.82±9.24) min in the Gamma nail group.The total dominant blood loss during operation and drainage was 100 ml.The mean operative time was(78.19±8.03) min in the dynamic hip screws group.The dominant blood loss during operation and drainage was 179 ml.The diffence of dominant blood loss was significant between the two groups(P0.01).The hidden blood loss was(418.05±35.69)ml in Gamma nail group and(666.13±73.15)ml in dynamic hip screws group,which accounted for 80.69% and 78.79% of total amount of bleeding respectively.Conclusions The incision of the Gamma nail group is more smaller than that in dynamic hips crew group,however,the total blood loss of the Gamma nail group is more.The hidden blood loss in perioperative period of femoral intertrochanteric fractures with Gamma nail should be taken into at tention.
