Local, Regional, and Spinal Anesthesia in Ruminants Flashcards
The globe, conjunctiva, nictitating membrane, and most of the eyelids are supplied by the
ophthalmic branch of the trigeminal nerve.
The extraocular muscles of the eye are innervated by the
trochlear nerve, the abducens nerve, and the oculomotor nerve.
The eyelids are innervated by the
auriculopalpebral n.
this block may be used for the repair of nasal lacerations and the placement of a nose ring for cattle
infraorbital nerve block
The infraorbital nerve is the continuation of the maxillary branch of the __ cranial nerve after it enters the infraorbital canal. this is covered by __ muscle

Anesthesia of the eye and orbit and immobilization of the globe that is necessary for such procedures as enucleation may be accomplished by performing a
retrobulbar block or Peterson block.
retrobulbar block causes
analgesia of the cornea, mydriasis, and prop- tosis.
Some possible adverse effects of retrobulbar injections include penetration of the globe, orbital hemorrhage, damage to the optic nerve, dysrhythmias caused by initia- tion of the ___ reflex, and injection into the optic nerve meninges.2

auriculopalpebral block
The Peterson eye block desensitizes what nerves
(oculomotor, trochlear, abducent, and trigeminal)
The proximal paravertebral nerve block desensitizes the dorsal and ventral nerve roots of the __ and ___ as they emerge from the intervertebral foramina.

The distal paravertebral nerve block desensitizes the dorsal and ventral rami of the spinal nerves ,,_at the distal ends of the transverse processes of __,___,__
