Radial artery is the preferred site for cannulation. Recently, the ulnar artery was chosen as an alternative in adults.
We aimed to measure the diameter and depth of the ulnar and radial arteries using ultrasound, and our secondary purpose was to evaluate their anatomical position using a near-infrared transcutaneous illumination device.
Forty-eight children (age range: 0-144 months) were assigned to the following groups: group Infant (aged <12 months), group Preschool (aged ≤12 to <72 months), and group School (aged ≥72 months). The diameter, depth, and position of the ulnar and radial arteries were compared between groups.
There was no significant difference between the diameters of the ulnar and radial arteries. In group Infant, group Preschool, and group School, mean diameters of the ulnar artery were 1.27 ± 0.15 mm, 1.62 ± 0.27 mm, and 2.03 ± 0.28 mm, respectively, and the radial artery were 1.29 ± 0.15 mm, 1.69 ± 0.27 mm, and 2.06 ± 0.29 mm, respectively. The corresponding differences between the diameters of ulnar and radial arteries were -0.02 mm, -0.07 mm, and -0.02 mm [95% CI -0.16 mm to 0.12 mm, -0.25 mm to 0.11 mm, and -0.25 mm to 0.21 mm; p = .776, p = .411, and p = .852]. In groups Preschool and School, the ulnar artery was at the recommended depth of 2-4 mm for arterial cannulation compared with the radial artery. In the Infant, Preschool, and School age groups, the ulnar and radial arteries were at the recommended depth of 2-4 mm for arterial cannulation in 70.0%, 100.0%, 93.8%, and 80.0%, 65.0%, and 50.0% of the cases, respectively. (difference: -10.0%, 35.0%, and 43.8%, 95%; CI -43.4% to 23.4%, 14.1% to 55.9%, and 19.4% to 68.1%, respectively).
The ulnar artery can be considered a promising alternative to the radial artery for facilitating arterial cannulation in children.
桡动脉是首选的插管部位。最近，尺动脉被选为成人的替代选择。
我们旨在使用超声测量尺动脉和桡动脉的直径和深度，我们的次要目的是使用近红外经皮照明设备评估它们的解剖位置。
将 48 名儿童（年龄范围：0-144 个月）分为以下组：婴儿组（年龄 <12 个月）、学龄前组（年龄 ≤12 至 <72 个月）和学龄组（年龄 ≥72 个月）。比较各组之间尺动脉和桡动脉的直径、深度和位置。
尺动脉和桡动脉的直径没有显著差异。在婴儿组、学龄前组和学龄组中，尺动脉的平均直径分别为 1.27±0.15mm、1.62±0.27mm 和 2.03±0.28mm，桡动脉的平均直径分别为 1.29±0.15mm、1.69±0.27mm 和 2.06±0.29mm。尺动脉和桡动脉直径之间的相应差异分别为 -0.02mm、-0.07mm 和 -0.02mm[95%CI-0.16mm 至 0.12mm、-0.25mm 至 0.11mm 和-0.25mm 至 0.21mm；p=0.776、p=0.411 和 p=0.852]。在学龄前组和学龄组中，尺动脉的深度为 2-4mm，适合动脉插管，而桡动脉的深度为 2-4mm。在婴儿、学龄前和学龄组中，尺动脉和桡动脉的深度分别为 2-4mm，适合动脉插管的比例分别为 70.0%、100.0%、93.8%和 80.0%、65.0%、50.0%。（差异：-10.0%、35.0%、43.8%、95%；CI-43.4%至 23.4%、14.1%至 55.9%和 19.4%至 68.1%）。
尺动脉可作为桡动脉的一种有前途的替代选择，有助于儿童进行动脉插管。
