Risk Factors Of Hidden Blood Loss In Intertrochanteric Fractures In Old Patients Treated With Proximal Femoral Nails Anti-rotation Blade

Objective To analyze the obvious and hidden blood loss and the risk factoers of hidden blood loss after operation intertrochanteric fractures in old patients treated with proximal femoral nails anti-rotation blade.Method A retrospective analysis was made on the clinical data of 165 cases of intertrochanteric fractures treated by PFNA from Jau,1,2010-Nov,1,2014, and the obvious, hidden blood loss after operations was univariate analyzed, using SPSS 13.0 statistical package.Result The mean blood loss of(542.68±128.44) ml was found in 165 cases after operations. The mean obvious blood loss was(142.93±55.03)ml,while the hidden blood loss was(389.97±76.79)ml,univariate analysis showed hidden blood loss was significantly higher in variable as follows:age,blood transfusion and bone mineral density.Conclusion There were much hidden blood loss in PFNA for inter-trochanter fracture internal fixation after operation. It is very important to supplement the blood volume during periopretive period.
