While modern clinical guidelines strongly advocate for ultrasound (USG) guidance, the traditional anatomical landmark technique remains widely utilized due to equipment availability or clinician habits. Proper positioning of the catheter tip is critical to prevent severe long-term complications; however, comparative data regarding catheter tip malposition between these two routine techniques-especially when confirmed by postprocedural bedside chest X-ray-require further prospective evaluation. Objective:\n\nThe primary objective of this prospective observational study is to compare ultrasound-guided versus landmark techniques for internal jugular vein catheterization with respect to catheter tip malposition, as determined by postprocedural bedside chest X-ray. Secondary objectives include the evaluation of the number of needle redirections, first-attempt success rate, total procedure time, and the incidence of mechanical complications (such as accidental arterial puncture or hematoma formation)",[58,59],"Catheter Malposition","Central Venous Catheterization","NOT_YET_RECRUITING","2026-07-08",{"date":63,"type":64},"2026-07-14","ACTUAL",{"date":66,"type":53},"2026-07-15",{"date":68,"type":53},"2026-10-15",{"name":5,"class":6}]
