Causes Of Recessive Blood Loss During Perioperative Treatment Of Intertrochanteric Fracture Of Femur By PFNA And Intervention Study

Objective:Interbone fracture occurs mainly in long bones such as femur,tibia,ulna and so on,mostly caused by violence.With the rapid progress of science and technology,surgical operation has successfully reduced the clinical mortality and disability rate greatly.However,the treatment of trochanteric fractures remains controversial due to different opinions.Therefore,the purpose of this study was to explore how to reduce perioperative bleeding by using antirotation proximal femur intramedullary nail treatment and different timing of surgery,so as to provide a more reliable basis for clinical treatment.Methods:In this retrospective study,the trauma department of Second Hospital of Shanxi Medical University was selected as the research object from December 2019 to June2020.The data related to femoral head fracture that was performed solely in this department with anti-rotation intramedullary nail surgery near the femur were analyzed and classified according to the time from injury to operation.The patients were divided into early and delayed operation groups with the limit of 48 hours.The preoperative and postoperative data were sorted and compared,including the general information of patients,body mass index,hemoglobin data,required hospitalization and actual length of stay,the amount of blood loss during surgery,the total cost of surgery and postoperative treatment,and the latent blood loss was calculated according to the Gross equation method.Statistical data were analyzed and collated.Results:Through data analysis and processing,a total of 82 patients with intertrochanteric fracture of femur receiving PFNA were involved in this study,including 40 patients in the early stage group with an average age of 76.49±10.27 years.Forty-two patients in the delayed group had an average age of 73.75±13.57 years.The results showed that the operation time,intraoperative blood loss,length of hospital stay and total hospitalization cost in the early group were significantly lower than those in the delayed group.The hemoglobin and RBC ratios of early group were higher than those of late group on day 3after surgery,and there was statistical significance(P<0.05).Overall blood loss and latent blood loss in the early group were significantly smaller than those in the delayed group,and there was statistical significance between the two groups(P<0.05).Conclusion:The summary found that early surgery after injury is crucial because it directly affects the amount of blood lost by patients.Performing the procedure within 48 hours will help improve the patient’s prognosis if the patient’s physical condition and family finances allow it.PFNA is a safe and effective treatment for intertrochanteric fracture of femur during perioperative period.PFNA technology is faster,less bleeding,less postoperative complications,and has a higher success rate than traditional fixation therapy.The PFNA technique has proven to be an effective treatment for intertrochanteric fractures of the femur,especially during surgery.It is worth reference for clinicians.
