The aim of this study was to assess the performance of pediatric-size oximetry catheters in diagnostic heart catheterization. Measurements of pressures and oxygen saturations were obtained with oximetry catheters as well as with standard methods during routine heart catheterizations in 10 infants and children with congenital heart defects. Maneuverability of the oximetry catheters was comparable to that of standard Swan-Ganz catheters. Pressure tracings were damped, but mean pressures were undistorted. Oxygen saturation measurements exhibited bias and scatter. It is concluded that no advantage is obtained by the use of oximetry catheters in diagnostic heart catheterization in children and infants.
本研究的目的是评估儿科尺寸的血氧饱和度测定导管在诊断性心导管插入术中的性能。在10例患有先天性心脏病的婴儿和儿童进行常规心导管插入术期间，使用血氧饱和度测定导管以及标准方法获取压力和血氧饱和度测量值。血氧饱和度测定导管的可操作性与标准的Swan-Ganz导管相当。压力曲线有衰减，但平均压力未失真。血氧饱和度测量存在偏差和离散度。得出的结论是，在儿童和婴儿的诊断性心导管插入术中使用血氧饱和度测定导管没有优势。
