Clinical analysis of obvious and hidden blood loss during treatment of intertrochanter fracture with proximal femoral nail anti-rotation / 中华创伤杂志

ABSTRACT

ObjectiveTo analyze the obvious and hidden preoperative and intraoperative blood loss during treatment of the intertrochanter fracture with proximal femoral nail anti-rotation (PFNA) so as to provide necessary data support for clinical perioperative treatment.MethodsThe clinical data of 216 patients with intertrochanteric fractured treated with PFNA between December 2005 and September 2010 were analyzed retrospectively.An analysis was done on preoperative and postoperative blood routine, perioperative and postoperative blood loss and transfusion, perioperative obvious and hidden blood loss and perioperative and postoperative blood transfusion.ResultsThe average blood loss was 48.9ml during operation, with no blood transfusion.Obvious hemochrome decrease (＜9 g/L) was found in 42 patients at 2-4 days after operation and the patients received blood transfusion for mean 300 ml.The mean obvious blood loss was 62.3 ml, while the mean hidden blood loss was 385 ml in all the patients.There was no obvious difference between males and females.ConclusionThe intertrochanter fracture is mostly seen in the elder patients.Compared with the minimal invasive operation, PFNA has more hidden blood loss, as indicates that much attention should be paid to the vital signs of the patients after surgery for prevention of the complications.
