A comparison of pudendal block vs dorsal penile nerve block for circumcision in children: A randomised controlled trial

We compared the analgesic and anaesthetic efficacy of pudendal nerve block with that of dorsal penile nerve block in male patients aged 3-5 years of age, undergoing elective circumcision. Thirty patients had a nerve stimulator-guided pudendal nerve block with two separate injection points 1.5-2 cm from the centre of the anus, and thirty patients received a dorsal penile nerve block. The same total anaesthetic volume of 0.3 ml.kg-1 was used in both groups. The pudendal nerve group showed significantly lower postoperative pain scores than the dorsal group (SD) (p < 0.05), and significantly fewer patients consumed analgesics in the pudendal group than the dorsal group: 0 vs 5 (17%) at 0 and 6 h, respectively. This study demonstrates the effectiveness of pudendal nerve block in comparison to the dorsal nerve block, with improved postoperative outcomes in children undergoing circumcision. © 2011 The Authors.
