Study on characteristics and relative factors of pulmonary function abnormality in 142 scoliosis patients

Objective To analyze the characteristics of pulmonary function abnormality in patients with scoliosis and to investigate it's clinical factors.Methods A total of 142 scoliosis patients' clinical data and preoperative pulmonary function were analyzed retrospectively,and the clinical factors of pulmonary function abnormality in patients with scoliosis were determined.Results The male patients had a higher severe scoliosis proportion and larger cobb's degrees than females.Moreover,the airway resistance showed that there was an increasing trend with the increase of patients' ages.Pulmonary function abnormality was related to the body weight of patients,cobb's degree and apex vertebrae position,while the scoliosis direction or kyphosis were not.Conclusion Along with the increase of age,the damage of pulmonary function was exacerbated and showed a changing form simple restrictive ventilatory disorder to mixed ventilatory disorder with obstructive ventilatory disorder.There was a positive correlation between the damage of pulmonary function and scoliosis.The patients with apex vertebrae located in thoracic vertebra may be more vulnerable to pulmonary function abnormality.The body weight in severe pulmonary function damage patients are affected,this brought enormous challenge to perioperative management.
