In 10 Skoliose-patients undergoing Harringtons-Operation, measurements of the oszillatory impedance and arterial blood gases were made intraoperatively. The resistance was elevated from the beginning without any change during the operation. The phase was in the inductive range with a further deviation during increasing extension. The possible reasons are the maximal rigidity of thorax and/or parenchyma or change in tracheobronchial "arborisation". Increase in dead space or changes in ventilation-perfusion ratio are suggested by the blood gas measurements. Further investigations will be necessary to determine, if the impedance of the lung is of value in determining the amount of intraoperative extension or postoperative lung function.
对10例接受哈林顿手术的脊柱侧凸患者在术中进行了振荡阻抗和动脉血气测量。电阻从一开始就升高，术中无任何变化。相位处于电感范围内，在伸展增加时进一步偏离。可能的原因是胸廓和/或实质的最大僵硬程度或气管支气管“分支”的变化。血气测量结果提示死腔增加或通气-灌注比改变。有必要进行进一步研究，以确定肺阻抗在确定术中伸展量或术后肺功能方面是否有价值。
