Vaginal probe ultrasound guidance for internal jugular catheterization

The use of ultrasound to assist needle cannulation of the internal jugular vein is well described. However, most ultrasound probes are too bulky to use easily on the neck. We describe a technique using a vaginal ultrasound probe to guide needle cannulation of the internal jugular vein. The small size of the vaginal probe permits visualization on the video screen of both the vein and the needle throughout the entire insertion of the needle, minimizing insertion attempts and preventing complications.
