I describe here a new, modified, ultrasound-guided penile block for male pediatric patients undergoing circumcision. The technique uses portable ultrasound with a linear probe and real-time scan at the base of the penis to identify vessels and fascia layers, which allows safe advancement of the needle and injection of local anesthesia bilaterally. The technique allows the practitioner to see local anesthetic distribution under the deep fascia of the penis. The procedure produces a subcutaneous wheal along the anterior side of the base of the penis or penoscrotal junction to achieve a complete penile block (Figure 1).
