This is a simple and safe block (don’t need large volume, not particularly close to any important anatomy) that can give you anesthesia of the anterior/lateral neck and ear. Consider it for ear lacerations, central line placement and clavicle fracture. It’s effectiveness can be variable but it is always worth a try. Here is a nice 5 minute video from 5minsono.
This IV has found the name peripheral IJ. It is a peripheral IV catheter that is inserted in the INTERNAL jugular vein under ultrasound guidance with sterile but non-barrier technique. It is really nice in patients who need access for less than 72 hours when the nurses (and you) are having trouble getting a traditional peripheral IV. Be sure to use a longer 2.5 inch catheter. 5 minute video here.
Using ultrasound for central line placement IS standard of care. 5minsono video here.
