Fig. 2

Upper panels show a 91-year male underwent the internal jugular vein catheterization using the single-plane approach, with two puncture attempts, with cannulation time of 335 s. Lower panels show a 69-year female underwent the internal jugular vein catheterization using the x-plane approach (simultaneous imaging both longitudinal and transverse views) with cannulation time of 179.6 s with the first-puncture single-pass catheterization success. a, d represents the needle was punctured into the target vein; b, e represents the guidewire was inserted into the target vein; c, f shows that the catheter was located within the vein after catheterization. White arrows show the needle track, white circle point of the needle, asterisk the common carotid artery, dashed arrows the guidewire, white triangle the catheter
