Abstract: Objective To investigate the postoperative complication rate in pediatric patients who underwent posterior scoliosis correction surgeries, and to identify its risk factors. Methods This study was a retrospective cohort study. Anesthetic data of pediatric patients who underwent posterior scoliosis correction surgeries from January 2015 to December 2017 in Peking Union Medical College Hospital were collected and analyzed. The clinical variables were subsequently compared between patients in whom postoperative complication occured (complication group) and those in whom did not (non-complication group). Binary Logistic regression analysis was performed to identify risk factors of postoperative complication in these patients. Results The study enrolled 580 patients. The postoperative complication rate was 5.7% and the independent risk factors leading to it included preoperative Cobb angle larger than 69.5° (OR=3.043, 95% CI:1.436-6.448, P＜0.01) and perioperative allogeneic transfusion(OR=2.364, 95% CI:1.095-5.102, P＜0.05). The postoperative transfer rate to Intensive Care Unit(ICU)(P＜0.01) in complication group was higher, with longer hospital stay length (P＜0.001) than that in the non-complication group. Conclusions The risk factors for postoperative complication in pediatric patients receiving posterior scoliosis correction surgeries include preoperative Cobb angle larger than 69.5° and perioperative allogeneic transfusion.
