General circumcision anesthesia is a local nerve block anesthesia, the use of lidocaine in the penile root injection of a circle, the penile nerve block can start the operation; anesthesia injection needle needs to be inserted into the subcutaneous tissue gap, so there will be a certain degree of pain, equivalent to intramuscular injections or venous puncture pain, but anesthesia drugs take effect very quickly, usually within a few seconds the pain will disappear. Therefore, the circumcision need not be too nervous, now the operation technology has been quite mature, and small trauma, fast recovery, generally in the outpatient can be carried out; for children and other patients who can not cooperate, can also be hospitalized in the general anesthesia surgery.
