Circumcision in older children and adults is mostly performed using local anesthesia. Circumcision is mildly painful during anesthesia and is usually well tolerated. In general, penile root anesthesia and local infiltration anesthesia are the most commonly used methods in clinical practice. With the development of medical devices, the traditional circumcision method is no longer done as a required procedure and disposable circumcision devices are replacing the traditional procedure. As the operating time is greatly reduced, the use of local anesthesia has become popular, greatly reducing the pain during the procedure. In the past, traditional circumcision usually took 30 minutes to an hour, and as the anesthesia is absorbed and metabolized, the patient still feels pain at the end of the procedure, so the introduction of new surgical methods is important to reduce the pain of the procedure. Most patients feel no pain during the procedure and tolerate it very well. In summary, circumcision is actually not very painful, and choosing a more advantageous surgical procedure can help a lot in reducing surgical pain. There will be a little pain when the anesthesia is injected, and the surgical pain disappears soon after the anesthesia takes effect, and there may be pain after surgery, which is generally tolerable.
