Design outcomes

Primary

Measure	Time frame
To Compare first-attempt success rate (successful cannulation with a single skin puncture and without needle withdrawal) for ultrasound-guided DPA cannulationTimepoint: From Cannula insertion until the appearance of blood backflow	—

Secondary

Measure	Time frame
1)Ultrasound localization time 2)Cannulation time 3)Total number of attempts for successful cannulation 4)Total procedure time 5)Number of needle redirections 6)To Evaluate Complication rates (Posterior wall puncture rate,Hematoma,Vasospasm, Arterial thrombosis 7)Subjective operator difficulty (Likert scale or VAS) Timepoint: 1)Baseline Time from probe contact to skin puncture 2)Time from skin puncture to flashback 3)From skin puncture until successful backflow achieved 4)Includes scanning, puncture, & securing the line 5)During Entire procedure 6)Immediately after completion of procedure within hour 7)After Completion of Procedure	—
