Primary analysis of the perioperative blood loss after surgery for elderly patients in intertrochanteric fractures

[Objective]To analyze the perioperative blood loss after surgery for elderly patients in intertrochanteric fractures and the relative factors to provide the data for clinical treatment in perioperative period.[Method]The clinical data of 38 cases of intertrochanteric fracture patients treated with DHS and 55 cases of intertrochanteric fracture patients treated with PFNA from October 2009 to October 2012 were retrospectively analyzed.All the cases were fresh intertrochanteric fracture following primary operation.According to Gross formulae,we calculated the total blood loss with the patients' height,weight,Hct,to evaluate the perioperative blood loss after Surgery.[Result]The mean hidden blood loss were 468 ml in DHS group,about 80.6% of the total blood loss volume.In PFNA group,the number was 554 ml and 89.4%.Hidden blood loss was the major part of the perioperative blood loss in intertrochanteric fracture.The blood loss was relative with the gender,age,height,weight,fracture type.There was significant difference in the blood loss between DHS group and PFNA group.[Conclusion]Much attention should be paid to the relative factors and the vital signs of the patients in the perioperative period,to supplement the blood volume during perioperative period after surgery in time to prevent the complications.
