Anesthetic Management of Patients After Scoliosis Surgery: A Single-Center Retrospective Study

Purpose To evaluate the effect of anesthetic management on scoliosis surgery and review the incidence rate of perioperative adverse events. Methods This was a retrospective study and approved by the ethics committee. Patients who underwent scoliosis surgery from April 2011 to March 2018 in the Third Hospital of ChengDu were enrolled in this study. Characteristics of patients were obtained from the hospital's electronic records. The following information on patients was collected: preoperative assessment details, premedication, type of anesthesia and operation, the main postoperative outcome, and complications. Data were presented as the mean +/- standard deviations (SD) for normally distributed continuous variables and numbers for categorical variables. Statistical analyses were performed using SPSS version 22.0. Results In total, 513 patients were enrolled in the present study. The main preoperative complication was cardiopulmonary dysfunction (386 cases, 75.24%). Anesthesia induction was performed with conscious tracheal intubation after oral surface anesthesia. In total, the common postoperative complications involved anesthesia (24 cases, 4.68%), surgery (23 cases, 4.48%), the respiratory system (138 cases, 26.90%), and the gastrointestinal tract (nine cases, 1.75%). The majority of postoperative complications were postoperative hypoxemia and hypercapnia, caused by poor cardiopulmonary function. Rare and serious complications still occurred. Three patients died in hospital. Conclusion Our study demonstrated a high incidence of complications in scoliosis surgery, especially postoperative complications. Extreme postoperative vigilance is required and high-level monitoring of conditions is highly recommended.
