瞄准看不见的静脉可能导致静脉穿刺并发症或失败。2014年11月，我们比较了用于静脉通路的隐形静脉与有形静脉的直径、深度和肤色，旨在提供信息以改进静脉穿刺技术。我们测量了动脉深度，以确定皮肤动脉与最近的静脉穿刺部位的距离。研究参与者为住院老年患者。用超声诊断仪测量静脉直径、静脉和动脉深度。对于直径2.3 mm和深度2.5 mm的静脉，可视化变得困难。离穿刺点最近的动脉最浅处为7.0mm。因此，静脉注射的静脉穿刺技术应通过瞄准深度为2.5至2.5的不可见静脉来改进。
Targeting invisible veins might result in venepuncture complications or failure. In November 2014, we compared the diameter, depth and skin colour of invisible veins used for intravenous access with those of visible veins, aiming to provide information to improve venepuncture techniques. We measured artery depth to identify how close skin arteries were to the nearest venepuncture site. Study participants were hospitalized elderly patients. Vein diameter and vein and artery depths were measured using ultrasonic diagnostic equipment. Visualization became difficult for veins with diameters 2.3mm and at depths 2.5mm. The shallowest depth of arteries nearest the puncture site was 7.0mm. Therefore, venepuncture techniques for intravenous injection should improve by targeting invisible veins with depths of 2.5 to
