Figure 2

Ultrasound- guided subclavian cannulation using in-plane approach. Subclavian and axillary veins were visualized by placing a linear transducer in the infra-clavicular fossa, to obtain a short axis view of vein and artery; then, the transducer was rotated until a longitudinal view was obtained (a) and tilted in order to visualize the vessel until its disappearance below the clavicle. In the longitudinal orientation, the needle was inserted at transducer midpoint providing an in-plane orientation (b).
