Study DesignCohort study.ObjectiveValidate the Surgical Apgar Score (SAS) as a means of predicting perioperative major complications occurring within 30 days after scoliosis surgery in pediatric patients with cerebral palsy (CP).Summary Of Background DataA patient's SAS, which is composed of three commonly recorded intraoperative variables, predicts postoperative complications after various types of spine surgery. This has not; however, been studied in pediatric patients with scoliosis and CP, a population that experiences a high incidence of complications after corrective spinal surgery.MethodsPediatric CP patients who underwent spinal correction surgery were included in this study. Patient background, surgical variables, and perioperative complications occurring within 30 days after surgery were collected. Patients were divided into 4 groups based on their SAS: SAS 0-4, SAS 5-6, SAS 7-8, SAS 9-10. The incidences of perioperative complications for each group were compared using a receiver operating characteristic analysis. Area under curve (AUC) is reported.ResultsA total of 111 patients met the inclusion criteria. There were no death cases. There were 44 (39.6%) perioperative major complications in 37 (33.3%) patients that occurred within 30 days after spine surgery. The most frequent perioperative complications were pulmonary issues (13.5%). The incidence of perioperative major complication in each SAS group was as follows: SAS 0-4; 51.6%, SAS 5-6; 30.2%, SAS 7-8; 18.5%, SAS 9-10; 0/0. When the SAS 7-8 group was set as the reference, there was no significant difference compared to SAS 5-6 (P=0.34), while the incidence rate was significantly increased in SAS 0-4 (P=0.02). The AUC was 0.65 (95% Confidence Interval: 0.54-0.75).ConclusionsOverall, there were 37 (33.3%) patients with CP who had a major complication within 30 days after spinal surgery. Lower SAS, with the 0-4 group being the cutoff, were associated with significantly higher complication rates than higher SAS groups.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
