A simplified method is presented to predict localization of the distal tip of the umbilical arterial catheter in thoracic aorta. When the segment of the catheter introduced equals a third of the length of the baby in cms., a correct position between the vertebral bodies of T-6 and T-10 was obtained in more than 90% of the cases. With this technique need to correct the position of the catheter and to obtain repeated roentgenographic controls is avoided.
本文提出了一种预测脐动脉导管远端在胸主动脉中位置的简化方法。当引入导管的长度（以厘米为单位）等于婴儿身长的三分之一时，在超过90%的病例中可获得导管位于T-6至T-10椎体之间的正确位置。采用这种技术可避免对导管位置进行校正以及反复进行X线检查。
