Idiopathic Scoliosis Impair Patients' Pulmonary Ventilation / 第二军医大学学报

ABSTRACT

Pulmonary ventilation function of 22 patients with idiopathic scoliosis was assessed. The results showed that there were significantly lower in Vital Capacity, Vita! Capacity % in predicted, Inspiratory Capacity, Forced Vital Capacity, Forced Expiratory Volume in Is, Maximal Voluntary Ventilation, and Maximal Voluntary Ventilation % in predicted of patients than those of age and sex matched normal controls. And there was no any statistical difference of Tidal Volume, Forced Expiratory Volume in Is % in predicted, Maximal Middle Flow, and Maximal Middle Flow % in predicted between two groups. Furthermore, the reduction of Vital Capacity % in patients with idiopathic scoliosis was correlated with the Cobb Angle, Wedge Index and rotation degree of the top vertebral body and not with the scoliosis direction and the patients' age.
