Exploration of the Clinical Effect of Different Autotransfusion Methods on Patients With Femoral Shaft Fracture Surgery.

OBJECTIVE: To explore the clinical effect of predeposit, salvage, and hemodilution autotransfusion on patients with femoral shaft fracture (FSF) surgery. METHODS: Selected patients with FSF were randomly divided into three groups: intraoperative blood salvage autotransfusion, preoperative hemodilution autohemotransfusion, and predeposit autotransfusion. Five days after the operation, the body temperature, heart rate, blood platelet (PLT), and hemoglobin (Hb) of patients were determined. The concentrations of EPO and GM-CSF in the three groups were calculated by ELISA. The content of CD14+ monocytes was calculated by FCM assay. The growth time and condition of the patient's callus were determined at the 30th, 45th, and 60th day after operation. Cox regression analysis was used to analyze the correlation between EPO, GM-CSF, CD14+ mononuclear content, callus growth, and autotransfusion methods. RESULTS: There were no statistically significant differences in body temperature and heart rate between the three groups (p > 0.05). PLT and Hb in the Predeposit group were markedly increased compared with that in the Salvage and Hemodilution groups. The concentrations of EPO and GM-CSF in the Predeposit group were markedly increased compared with that in the Salvage and Hemodilution groups. The content of CD14+ monocytes in the Predeposit group was significantly higher than that in the Salvage and Hemodilution groups. Predeposit autotransfusion promotes callus growth more quickly. CONCLUSION: Predeposit autotransfusion promoted the recovery of patients with FSF after the operation more quickly than salvage autotransfusion and hemodilution autotransfusion.

Pediatric femoral shaft fractures: the American Academy of Orthopaedic Surgeons clinical practice guidelines versus actual management in a teaching hospital.

Background: In 2009, the clinical practice guidelines (CPG) were released by the American Academy of Orthopaedic Surgeons (AAOS), which outline an age-based approach for treating pediatric femoral shaft fractures (PFSF), both nonoperatively and operatively. The aim of the current study was to investigate potential disparities between the recommended treatments for PFSF based on the AAOS-CPG and the actual treatments administered in The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University. Methods: A retrospective review was conducted on the medical charts and radiographs of all PFSF treated at The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University from January 2014 to January 2022. We identified 445 children who met our inclusion criteria and evaluated their treatments according to the AAOS-CPG. Actual treatments were then compared with the treatments recommended by the AAOS-CPG. Binomial and multivariate logistic regression was used to examine whether different factors could predict the choice between operative and nonoperative management. Results: Operative treatments were undertaken in 102 of 215 (47.4%) fractures in children younger than 6 years, in 102 of 122 (83.6%) fractures in those between 6 and 12 years of age, and in 107 of 108 (99.1%) fractures in those older than 12 years. Nonoperative management was conducted in 113 of 215 (52.6%) fractures in children younger than 6 years, in 20 of 122 (16.4%) fractures in those between 6 and 12 years of age, and in 1 of 108 (0.9%) fractures in those older than 12 years of age. Surgeon decisions for non-surgery were in agreement with the CPG 52.6% of the time, whereas agreement reached 90.9% for surgical choices. Predictors of actual operative management were age (P=0.01), patient weight (P<0.001), fracture pattern (P<0.001), presence of other orthopedic injuries requiring surgery (P=0.002), and polytrauma (P=0.02). Conclusions: There was limited concordance between actual treatments and CPG recommendations, particularly for the nonoperative management of fractures in children under 6 years old. Age, patient weight, fracture pattern, presence of other orthopedic injuries requiring surgery, and polytrauma were the main predictors of our operative decision-making process.
