placement of a nose ring
Infraorbital nerve block
Blocks the lower eyelid only
Auriculopalpebral nerve block

trochlear, abducent, and trigeminal)
responsible for sensory and motor
function of all structures of the eye except
the eyelid
Peterson Eye Block
Desensitizes the nerves (oculomotor,
trochlear, abducent, and trigeminal)
responsible for sensory and motor
function of all structures of the eye except
the eyelid
Peterson Eye Block

Mydriasis,
Proptosis
Retrobulbar Block
Desensitizes the dorsal and ventral nerve
roots of the last thoracic (T13) and first
and second lumbar (L1 and L2) spinal
nerves as they emerge from the
intervertebral foramina.
Proximal Paravertebral Nerve Block
Desensitizes the dorsal and ventral rami
of the spinal nerves T13, L1, and L2 at
the distal ends of the transverse
processes of L1, L2, and L4, respectively
Distal Paravertebral Nerve Block
Desensitize a selected area of the
paralumbar fossa
Line Block
Locally blocks the tissue bordering the
caudal aspect of the thirteenth rib and the
ventral aspect of the transverse
processes of the lumbar vertebrae.
Line Block
Typically does not block the peritoneum
Inverted L Block

Sacral paravertebral nerve block
Provides analgesia to the anus, vulva,
and vagina
Sacral paravertebral nerve block
Standing bull:

distal to the sigmoid flexure and
examination of the penis

Surgical procedures of the penis:
- repair of prolapses,
- removal of perianal tumors,
- removal of penile papillomas or
warts,
- other minor surgeries of the penis
and prepuce
Internal Pudendal Nerve Block
Standing bull:
- Penile relaxation and analgesia
distal to the sigmoid flexure and
examination of the penis
Internal Pudendal Nerve Block
Desensitized at a location just proximal to
the surgical site
Dorsal Penile Nerve Block
Desensitizes the sensory fibers in the
spermatic cord
