BLOOD TRANSFUSION PREDICTIVE FACTORS IN DEGENERATIVE SPINE SURGERY
Journal Title: Journal of Turkish Spinal Surgery - Year 2012, Vol 23, Issue 3
Abstract
Background and Objectives: Spinal surgery frequently requires allogenic blood transfusion to compensate for major blood loss. Autologous blood donations are often used to reduce homologous transfusion. In the last few decades, interbody spinal fusion has gained in popularity and is frequently performed in many spinal procedures; however, there are few studies that evaluate the risk factors of additional blood transfusions in the postoperative course of degenerative spine surgery, and no studies concerning patients who have undergone interbody fusion. Materials and Methods: In 15 consecutive months, in the same Spinal Surgery Department, 40 different elective spine surgeries were performed. These were divided into four groups: laminectomy alone, laminectomy with instrumented posterolateral fusion, laminectomy with instrumented posterolateral and interbody fusion, and extensive instrumented fusion. All patients’ surgery-related data were respectively recorded, including patient age, gender, diagnosis, preoperative hemoglobin rate, autologous blood availability, number of spinal levels decompressed and fused, duration of surgery, type of surgical procedure, and duration of hospital stay. These data were statistically analyzed to determine whether any of the variables could determine a higher risk of blood transfusion. Results and Discussion: In a univariate analysis of factors influencing the need for blood transfusion, no significant relationship was found with patient age or availability of autologous blood before surgery. A significantly greater risk of blood transfusion was observed for females, and in cases with a low preoperative Hb rate, longer surgical times, multiple spinal levels decompressed or fused, and longer durations of hospital stay were observed. Patients undergoing instrumented posterolateral fusion or extensive instrumented fusion are also exposed to a higher risk of blood transfusion. Our linear multiple regression model showed that the patients’ gender and an increased number of levels decompressed and/or surgically fused were significant determinants for the need for blood transfusion.

DOES THE SAGITTAL ORIENTATION OF THE PEDICLE SCREW AFFECT BIOMECHANICAL STABILITY? A FINITE ELEMENT STUDY
Background: One of the most important steps in obtaining a successful outcome in spine surgery is appropriate placement of the pedicle screw. To test the hypothesis that sagittal angle of pedicle screw affects the bio...
METHODS OF SURGİCAL TREATMENT FOR THE PRIMARY TUMORS OF THE SPINE
Primary tumors of the spine are rarely seen. When they are located on the body or posterior elements, the patient first complains of back ache. After an appropriate diagnostic evaluation, the next step would be preoperat...
