Difficult IV access

Difficult IV access refers to challenges encountered when attempting to insert an intravenous (IV) catheter due to anatomical or physiological factors, making venous cannulation complex. In medical procedures, this often necessitates the use of ultrasound guidance to visualize veins, enhancing success rates and minimizing patient discomfort. This procedural difficulty is a common concern in emergency medicine and critical care.

Optimizing IV access with ultrasound ensures precise needle placement, reduces complications, and improves patient outcomes, particularly in those with a history of failed attempts, obesity, dehydration, or chronic illness. Ultrasound-guided IV placement is now a standard practice, essential for efficient and safe venous access in challenging clinical scenarios.
