Emergency department ultrasonography guided long-axis antecubital intravenous cannulation: How to do it.

An 85-year-old woman with a past medical history of severe peripheral vascular disease and right below knee amputation presented to the emergency department with a 1-day history of non-positional dizziness and weakness. The patient required intravenous access to work up her dizziness and weakness. The patient had multiple failed blind ED peripheral IV attempts performed in the past. Emergency department bedside ultrasonography with a high frequency linear array vascular probe was used to guide antecubital brachial vein cannulation on the first attempt using the long-axis approach.
