A clinician administered an IA nerve block with a long, 25 gauge needle. Although no contact with bone was made, she was certain that the penetration depth was adequate because only 3 mm of the needle was visible. She confirmed negative aspiration in two planes and deposited one cartridge of 2% lidocaine with 1:100,000 epinephrine. After several minutes, the patient's teeth were not numb however the side of their face, including the lower eyelid, around the mouth and chin, were extremely numb.
-If bone is not contacted after repositioning the needle, what is the appropriate procedure?
