青少年脊柱侧弯的肺功能研究

Study of Pulmonary Function in Adolescent Idiopathic Scoliosis Patients

作者研究了４８７例无症状青少年特发性脊柱侧弯患者肺通气功能，并以正常同龄青少年２５０例作对照。结果表明：患者肺活量，肺活量占预计值百分比，深吸气量，用力肺活量，１秒钟用力呼气容积，最大通气量，最大通气量占预计值的百分比较同龄正常组明显降低；而潮气容积，１秒钟用力呼气容积占用力肺活量比值，最大呼气中段流量，最大呼气中段流量占预计值的百分比与对照组无显著性差异。并进一步研究表明：肺活量占预计值的百分比的降低与脊柱侧弯的Ｃｏｂｂ角、侧弯顶椎的椎体楔变度及旋转度发病年龄有关，而与脊柱侧弯方向无关。

ulmonary ventilation function of 487 patients with adolescent idiopathic scoliosis was assessed.The results shouldthat there were significant lovver in vital capacity. vital capacity%in predicted ventilation,and maximal voluntary ventila-tion%in predicted of patients than those of age and sex matched normal controls.And there was no statistical difference oftidel volume. forced expiratary in 1%in predicted.Maximal middle flow and maximal middle flow%in predicted betweentwo groups.Furthermore,the reduction of vital capacity%in patient with idiopathic scoliosis was correlated with the Cobbangle, wedge index and votation degree of the top vertebral body and not with the scoliosis direction and patients age.(Origi-nal articles on page81)
