The pathway of the radial artery of 23 patients, ranging in age from 17 days to 10 years, was located with a small-caliber Doppler probe, 1.5 mm in diameter, and the artery was punctured along the pathway traced on the skin surface. In all patients the arterial pathway, including its branch and diameter, was shown clearly. In 11 patients, ranging in weight from 5 to 24 kg, the artery was greater than 0.5 mm in diameter and was cannulated easily. In another 4 patients, all less than 3 kg in weight, the artery under the thin skin layer was cannulated successfully in three of them. However, among the remaining 8 patients, ranging in weight from 3 to 5 kg, cannulation was successful in only two cases. The thick tissue layer, including the skin and the subcutaneous layer over the small artery, was thought to interfere with the accurate location of the artery in the other six patients. Nevertheless, the arterial pathway traced on the skin surface facilitated successful percutaneous cannulation by another method in these six. Visualization of the arterial pathway by the small-caliber Doppler probe was thought to be helpful for percutaneous cannulation, with or without another cannulation method.
对23例年龄从17天至10岁的患者，使用直径1.5毫米的小口径多普勒探头确定桡动脉的走行，并沿皮肤表面所确定的走行对动脉进行穿刺。所有患者的动脉走行，包括其分支和直径，均清晰显示。11例体重5至24千克的患者，动脉直径大于0.5毫米，易于插管。另外4例体重均小于3千克的患者，其中3例成功对薄皮肤层下的动脉进行了插管。然而，其余8例体重3至5千克的患者中，仅2例插管成功。认为包括皮肤和小动脉上方皮下层在内的厚组织层在另外6例患者中干扰了动脉的准确定位。尽管如此，在这6例患者中，通过另一种方法，皮肤表面所确定的动脉走行有助于成功进行经皮插管。小口径多普勒探头对动脉走行的可视化被认为对经皮插管有帮助，无论是否使用另一种插管方法。
