Ultrasound guidance is now the standard of care when placing a central venous catheter (CVC), resulting in decreased complications and increased first-pass success rates. However, even with ultrasound guidance being used for the initial venipuncture, misplacement of a CVC in either an unwanted vein or in an artery still occurs. Here, we discuss a simple technique to assist in the adequate placement of the CVC in the vena cava using bedside echocardiography.
超声引导现在是放置中心静脉导管(CVC)的标准护理方法,可降低并发症发生率并提高首次穿刺成功率。然而,即使在初始静脉穿刺时使用了超声引导,CVC 仍可能被放置在不希望的静脉或动脉中。在这里,我们讨论了一种简单的技术,使用床旁超声心动图来帮助将 CVC 正确放置在腔静脉中。
