The subclavian vein is a commonly used venous access route. Percutaneous cannulation is associated with complications and malpositioning of the catheter. We studied the potential effect of various body positions on subclavian vein catheterization using gross anatomic dissection and magnetic resonance imaging. Findings show that traditional recommendations for patient positioning with the shoulders retracted and the head turned away can act to distort the subclavian vein anatomy and make successful cannulation more difficult. Positioning the patient flat with the head and shoulders in a neutral position is suggested.
锁骨下静脉是常用的静脉穿刺途径。经皮插管会引发并发症及导管位置不当。我们通过大体解剖和磁共振成像研究了不同体位对锁骨下静脉插管的潜在影响。研究结果表明，传统的患者体位建议，即肩部后缩、头转向一侧，可能会扭曲锁骨下静脉的解剖结构，增加成功插管的难度。建议将患者平卧位，头和肩部保持中立位。
