title: Risk factors affecting the immediate postoperative course in pediatric scoliosis surgery.
abstract: METHODS
  A retrospective analysis of pediatric records of idiopathic scoliosis (IS) and neuromuscular scoliosis (NMS) etiology, in a search for complications and their risk factors immediately following surgical repair.
  
  
  OBJECTIVE
  To evaluate the influence of pre- and intraoperative parameters on the postoperative course and lay the cornerstone for a course-prediction model.
  
  
  BACKGROUND
  Only a few studies have addressed the immediate postoperative complications of pediatric scoliosis surgery.
  
  
  METHODS
  Our study included all children who underwent spinal fusion for scoliosis in our hospital between 1998 and 2006. The following data were collected: curve etiology, Cobb angle, number of fused vertebrae, fusion approach, and the addition of thoracoplasty. We evaluated the influence of this data on the rate of delayed extubations, length of intensive care unit (ICU) hospitalization, and the presence of major and minor immediate postoperative complications.
  
  
  RESULTS
  The study included 126 children (95 IS and 31 NMS). Delayed extubations were recorded in 17 children (3% of IS vs. 45% of NMS). The most common major and minor complications were pulmonary and hematological-biochemical, respectively. Overall pulmonary complications (major and minor) were recorded in 38 children. Major complications (of any category) were recorded in 19 children. Average length of ICU hospitalization was 3.8 days. The rate of complications in the NMS group was significantly higher than in the idiopathic group. Posterior fusions were associated with a significantly lower rate of pulmonary complications and shorter ICU hospitalizations, in comparison to anterior and combined fusions. Cobb angle, number of fused vertebrae, and the addition of thoracoplasty did not correlate with any postoperative parameters.
  
  
  CONCLUSIONS
  While NMS etiology, anterior and combined fusions correlated with a worse course, the Cobb angle, number of fused vertebrae, and the addition of thoracoplasty did not. Optimization of postoperative care should be carried out accordingly. Scoliosis surgery is safe even in extreme curves and long fusions. Thoracoplasty can be added whenever indicated, in order to improve the overall outcome.
