Pudendal Nerve Block

Patient Position: The patient lies supine.

Indications: Anesthesia of the posterior part of the scrotum.

Needle Size: A very short beveled needle.

Volume: 0.1 mL/kg of ropivacaine 0.2% for children up to 7 years, levobupivacaine 0.5% for older children, up to 5 mL per side.

Anatomic Landmarks: Ischial tuberosity.

Approach and Technique:
The patient is supine with the knees flexed and the plantar part of his
feet joined. Mark the skin projection of the ischial tuberosity on both
sides. At this level a very short beveled needle is inserted in a
medial direction until a loss of resistance corresponding to the
piercing of the obturator fascia is felt.
