Regional anesthesia for office procedures: Part II. Extremity and inguinal area surgeries.

The hand can be anesthetized effectively with blocks of the median, ulnar, or radial nerve. Each digit is supplied by four digital nerves, which can be blocked with injections on each side of the digit. Anterior or posterior ankle blocks can be used for regional anesthesia for the foot. The anterior ankle block, which is used for procedures on the dorsum of the foot, involves blocking the saphenous nerve, and superficial and deep peroneal nerves. The posterior ankle block, which is used to anesthetize the sole of the foot, involves blocking the sural and posterior tibial nerves. Paracervical block is used for procedures on the cervix, such as loop electrocauterization or conization. Dorsal penile block has been the most commonly recommended anesthetic technique for neonatal circumcision. A safe and effective alternative is the application of anesthetic cream over the skin to be circumcised.
