Dynamic Multiplanar Real Time Ultrasound Guided Infraclavicular Subclavian Vein Catheterization
Ultrasound guided vascular access has been well-characterized as a safe and effective technique for internal jugular and femoral vein catheterization. However, there is limited experience with the use of ultrasound to access the infraclavicular subclavian vein. Multiple ultrasound techniques do exist to identify the subclavian vein, but real time access is limited by vessel identification in a single planar view. To overcome this limitation, a novel technique of ultrasound guided infraclavicular subclavian vein catheterization using a real time multiplanar approach has been developed. The initial experience with this approach is described. A single surgeon used combined oblique, transverse, and longitudinal views along with Doppler color flow images to both define the infraclavicular anatomy and to obtain subclavian vein access in 42 adult patients (20 M/22 F and 22 L/20 R) with a mean body mass index of 29.2 (range = 18.9‐55.4). Chest x-ray was obtained to confirm position and to rule out pneumothorax. Subclavian vein cannulation was achieved in 100 per cent of patients; subsequent catheterization was successful in 92.9 per cent. The number of attempts required for cannulation averaged 1.3 (range = 1‐5), and decreased after a five patient learning curve. No patient developed a pneumothorax, hematoma, or cannula malposition. Ultrasound guided multiplanar infraclavicular subclavian vein access appears to be a safe and effective adjunct for central line placement.
