AbstractDorsal penile nerve block (DPNB) is a useful procedure for analgesia in circumcision. It has minor complications and a reported failure rate of from 4% to 6.7%. To evaluate the intraoperative value of additional anesthesia of the perineal nerves--a branch of the pudendal nerve--during circumcision, we conducted a prospective randomized double-blind study on 250 adults. The postoperative period was not studied. The subpubic space technique of DPNB was used. Patients received DPNB (Group I) or DPNB with an additional ventral injection (Group II) for perineal nerve analgesia. Seventeen patients (13.6%) from Group I suffered pain. Of these, nine (7.2%) had discomfort and mild pain but no supplemental analgesia was needed. In the remaining eight patients, however, it was necessary to add local analgesia. This represents a total failure rate of 6.4%. On the other hand, only six patients (4%) in Group II had a mild diffused discomfort with no need for additional local anesthesia (P < 0.01). The average operating time was 12.4 +/- 2.7 min (range 9-22 min) in Group I and 10.7 +/- 1.6 min (range 8-15 min) in Group II (P < 0.001). We think that perineal nerves play an important part in innervation of the penis and must be anesthetized during the penile block.
