Ultrasound guided dorsal penile nerve block in children

Anaesth Intensive Care. 2007 Apr;35(2):266-9. doi: 10.1177/0310057X0703500217.

Abstract

We describe a technique for using a portable ultrasound scanner (38 mm broadband (10-5 MHz) linear array transducer (Sonosite Titan SonoSite, Inc. 21919 30th Drive SE Bothell, WA.)) to guide dorsal penile nerve block in children under general anaesthesia. Real-time scanning is used to guide bilateral injections into the sub-pubic space, deep to Scarpa's fascia either side of the midline fundiform ligament. Scanning can confirm that the local anaesthetic has spread to contact the deep fascia on each side. A subcutaneous wheal of local anaesthetic along the penoscrotal junction completes the block.
