How To Do an Ulnar Nerve Block
Warnings and Common Errors
To minimize the risk of needle breakage, do not bend a needle, insert it to its full depth (ie, to the hub), or attempt to change direction of the needle while it is inserted. To help prevent nerve injury or intraneural injection, instruct patients to report paresthesias or pain during the procedure. To help prevent intravascular injections, aspirate before injecting. Always maintain ultrasound visualization of the needle tip during insertion. If using ultrasound, always maintain ultrasound visualization of the needle tip during insertion.
