Background: The purpose of this study was to determine the prevalence of non-neurologic complications following surgery for scoliosis and to identify factors that can increase this risk.
Methods: The demographic data, medical and surgical histories, and prevalence of non-neurologic complications were reviewed in a retrospective cohort of 602 patients, who had undergone corrective surgery for scoliosis between January 2001 and June 2011.
Results: There were 450 patients under 20 years old (U20) and 152 of patients above 20 years old (A20) enrolled in this study. Forty-nine patients in U20 (10.9%) and 18 patients in A20 (11.8%) had post-operative complications. Respiratory complications were most common in U20 (4%) and gastrointestinal complications were most common in A20 (7%). There was no significant difference between the 2 groups in the prevalence of complications. Logistic regression revealed that factors that correlated with an increased odds for complications were Cobb angle (P = 0.001/P = 0.013, respectively), length of operation time (P = 0.003/P = 0.006, respectively), duration of anesthesia (P < 0.001/P = 0.005, respectively) and transfusion (P = 0.003/P = 0.015, respectively) in U20 and A20. Also, comorbidities (P = 0.021) in U20, and decreased body mass index (P = 0.030), pre-operative forced vital capacity (P = 0.001), forced expired volume in 1s (P = 0.001), increased numbers of vertebrae fused (P = 0.004), blood loss (P = 0.001) in A20 were associated with increased odds for complications.
Conclusions: There was no difference in the prevalence of complication in scoliosis patients by age. The prevalence of complication was dependent on Cobb angle, length of operation time, duration of anesthesia and transfusion of PRBC. Deterioration of preoperative pulmonary function significantly increased risk of post-operative complications in adult patients.
