应用超声测量婴幼儿双侧桡、尺动脉的对比研究

目的 应用超声测量并分析婴幼儿双侧桡、尺动脉的内径及深度以探讨婴幼儿在超声引导下行桡、尺动 脉穿刺置管的差异性。方法 选取择期行全麻手术的婴幼儿120例，应用超声对患儿双侧桡、尺动脉进行检查测量， 记录双侧桡、尺动脉3个标志点的深度、内径及解剖变异情况，同时记录患儿的身高、体质量、禁饮禁食时间以及每个 测量时刻的平均动脉压（MAP）、心率（HR）和体温。结果 超声测得的患儿左、右前臂间桡动脉和尺动脉深度、内径 差异无统计学意义；双侧桡动脉均较尺动脉表浅（P＜0.05）。桡、尺动脉第2测量标志点深度较第1测量标志点深，第 3测量标志点较第2测量标志点深（P＜0.05）；桡、尺动脉内径在各个测量标志点间的比较差异无统计学意义。双侧 桡、尺动脉深度与年龄、身高、体质量、MAP均呈负相关，与HR呈正相关（P＜0.01）；双侧桡、尺动脉内径与年龄、身 高、体质量、MAP均呈正相关，与HR均呈负相关（P＜0.01）。结论 超声测得婴幼儿桡、尺动脉内径相当；在超声引 导下行婴幼儿桡、尺动脉穿刺置管均具有选择性价值。

Comparative study on ultrasound measurement of bilateral radial and ulnar arteries in infants

Objective To explore the difference of ultrasound-guided radial and ulnar artery catheterization by measuring the inner diameter and depth of the bilateral radial and ulnar arteries in infants. Methods A total of 120 infants selected for elective surgery in our hospital underwent general anesthesia were included in this study. The depth, inner diameter and anatomical variation of the three mark points of bilateral radial and ulnar arteries were recorded. At the same time, the height, body weight, time of abstaining from drinking and fasting, the mean arterial pressure (MAP), heart rate (HR) and body temperature of children were recorded. Results There were no significant differences in the depth and inner diameter of radial artery and ulnar artery measured by ultrasound between the left and right forearms. Both radial arteries were superficial than ulnar arteries (P＜0.05). The depth of the second measurement mark point of radial and ulnar artery was deeper than that of the first measurement mark point, and the third measurement mark point was deeper than that of the second measurement mark point (P＜0.05). There were no significant differences in internal diameters of radial and ulnar arteries between all measurement mark points. The depth of bilateral radial and ulnar arteries was negatively correlated with age, height, body weight and MAP, and positively correlated with HR (P＜0.01). The internal diameters of bilateral radial and ulnar arteries were positively correlated with age, height, body weight and MAP, and negatively correlated with HR (P＜ 0.01). Conclusion The inner diameters of radial and ulnar arteries in infants under ultrasound are similar. The ultrasoundguided arterial puncture of radial and ulnar arteries in infants has selective value, and which is worthy of further study.
