How can correct placement of a CVAD be confirmed?

• A. By visual inspection only
• B. Via imaging, typically chest X-ray, or aspiration of blood
• C. By palpating the catheter
• D. By measuring blood pressure

Answer: (B)

The confirmation of correct placement of a Central Venous Access Device (CVAD) is essential to ensure safe and effective use. Imaging, particularly a chest X-ray, is the gold standard for verifying that the catheter is properly positioned within the central venous system. This imaging allows healthcare providers to visualize the catheter’s placement in relation to anatomical structures, ensuring it is in the superior vena cava or other appropriate area, minimizing the risk of complications. In addition to imaging, aspiration of blood can provide confirmation that the catheter is correctly placed within a central vein. A successful aspiration of bright red venous blood indicates that the catheter is in a vein where blood flow is occurring, further validating correct placement. Using visual inspection alone is insufficient, as it cannot provide definitive confirmation about the position of the catheter tip or its relationship with surrounding structures. Palpating the catheter is not a reliable indicator of placement, as it does not assess the internal position of the catheter. Measuring blood pressure is not an effective method for confirming CVAD placement, as blood pressure readings can be influenced by many variables unrelated to catheter position. This solidifies why imaging and aspiration are the appropriate methods for confirming CVAD placement.
