Twenty girls, aged 11-15 years, with adolescent idiopathic scoliosis were studied before spinal fusion was performed. Each underwent a range of lung function tests and a standardised progressive exercise test on a bicycle ergometer. The resting lung function tests showed reduced peak flow rates, lung volumes, and maximum voluntary ventilation. The maximum oxygen uptake was slightly diminished but maximum exercise ventilation was normal. The latter was achieved by using a greater than normal fraction of the vital capacity in tidal breathing while exercising. Mild hyperventilation during submaximal exercise and a trend towards an exercise tachycardia with increasing body weight were observed.
对20名年龄在11至15岁之间、患有青少年特发性脊柱侧弯的女孩在进行脊柱融合手术前进行了研究。每个人都接受了一系列肺功能测试以及在自行车测力计上进行的标准化渐进性运动测试。静息肺功能测试显示峰值流速、肺容量和最大自主通气量降低。最大摄氧量略有下降,但最大运动通气量正常。这是通过在运动时潮气量呼吸中使用大于正常比例的肺活量来实现的。观察到在次最大运动期间有轻度过度通气,并且随着体重增加有运动性心动过速的趋势。
