Ring block anesthesia for circumcision

Ring block anesthesia is a type of anesthesia used for circumcision. A health professional injects a numbing medication (such as lidocaine) in a ring pattern around the shaft of the penis. About three injections are made to complete the ring pattern. The injections may cause some pain or bruising.

This type of anesthesia may provide the most effective pain prevention for circumcision.
