Prediction of massive blood loss in scoliosis surgery from preoperative variables
i) Study design: Single center retrospective cohort study
ii) Preoperative Cobb angle more than 50º (P = 0.017, odds ratio = 2.47, 95% confidence interval: 1.17-5.20), the number of fused levels more than 6 (P = 0.014, odds ratio = 3.70, 95% confidence interval: 1.31-10.49), and osteotomy (P = 0.000, odds ratio = 4.64, 95% confidence interval: 1.97-10.94) were determined to be the independent risk factors of massive blood loss in scoliosis surgery.
