Umbilical vein catheterization is the fastest route to central access in a newborn who needs resuscitation. When a neonate needs epinephrine, fluid, or glucose and peripheral access fails, the umbilical vein is right there. In this video, Dr. Elizabeth Yim walks step by step through emergency umbilical vein catheterization. She covers flushing the catheter, tying off the base of the cord, and cutting a clean stump. She then shows how to find the vein: a single large, thin-walled vessel, usually at 12 o’clock, set apart from the two smaller, thick-walled arteries. The catheter goes in only until blood draws back freely, which leaves the tip in a low-lying position for emergency use. Safety points run throughout: keep air out of the line, confirm blood return before giving anything, and do not advance farther than you need to.
