“…An approach described in literature is puncture of the axillary vein as alternative to the subclavian vein, since it is easily visualized with US, more laterally located, associated with a longer distance between the probe and clavicula make dynamic insertion easier, with lower complication rates than the traditional method. (29)(30)(31) Peripheral veins should be used as first option in an emergency setting, however, some clinical situations, for instance, edematous patient, obesity, among others, make the insertion difficult. US, preferentially the linear ones (high resolution and discernment of structures with less than 1mm) make possible catheterization, using cross-sectional or longitudinal axes of basilica, cephalic and or axillary veins.…”
