Summary

Pediatric circumcision has been realized since the beginning of human civilization. In the United States, a 2014 review revealed a 81% prevalence of men 14-59 years old being circumcised.

Circumcision surgery is mostly performed on an ambulatory basis. The best analgesia technique for this procedure has yet to be determined. Local, regional, general anaesthesia or even combinations have been described. The Dorsal Penile Nerve Block (DPNB) has been shown to be superior to topical analgesia in neonatal circumcision. A 2008 Cochrane review showed no difference in pain scores between caudal block and DPNB, but described more motor block with caudal block. For this reason, the 2017 Canadian Urological Association guidelines review recommends using DPNB with a ring block as a standard of care for neonatal circumcision with-out general anaesthesia. However, DPNB does not provide reliable coverage of the ventral surface of the penis and frenulum. Pudendal nerve block (PNB) is another regional anaesthesia technique gaining in popularity with the now widespread use of ultrasound guidance. However, it is still unclear if PNB can give better outcomes than DPNB. The ultrasound-guided pudendal nerve block has only been recently described and was not reviewed as an option at the time of the guidelines writing.

PNB can be performed using surface landmarks, with nerve stimulation or with ultra-sound-guidance. It has already been proven to have lower surgical complication rates than caudal block for hypospadias surgeries. Regarding DPNB, a variety of techniques have been described using either surface landmarks or ultrasound guidance. In the past ten years, two RCTs in Lebanon and Turkey compared PNB and DPNB for penile surgeries, showing lower pain scores and lower narcotics consumption in the pudendal nerve block group. None of these studies used ultrasound-guidance.

The investigators perform more than a hundred pediatric circumcisions yearly for medical indications. The surgery is done under general anaesthesia in association with either PNB or DPNB, depending on the anesthesiologist's preference. The primary objective is to compare analgesia between the two blocks during and after pediatric circumcisions to minimize post-operative pain. The research team will compare peri and postoperative pain in children receiving either ultrasound-guided pudendal nerve block or ultrasound-guided dorsal penile nerve block for circumcision surgery.
