Head tilt Flashcards
What is the immediate treatment of the rolling rabbit
Place in O2 cage with towels
Let the rabbit roll
No Dx or treatment while still rolling (prevent fracture or other trauma)
Wait until rolling has stopped
History forms
Important information about history for rolling rabbit/head tilt
When did it start
Trauma
Parasite prevention
First episode?
Diet
Where was it adopted and when
Neurological exam in a rolling rabbit
side of the head tilt
Nystagmus?
CP?
Differential for head tilt
Vestibular disease
- CNS: Toxin (lead), bacterial infections, baylisascaris (outdoor), encephalitoozon, degenerative disease, neoplasia
- PNS: Otitis media/interna, head trauma, iatrogenic ear cleaning, unlikely 9polys, neoplasia, aminoglycoside toxicosis), otoconia/otoliths 95-99% of head tilt PNS and it is due to calcium prticles floating in the endolymph
**Vestibular disease is not usually seen with external parasite or even bacterial otitis
Differenciating CNS and PNS disease for a head tilt in rabbit
Will both have head tilt and dysequilibrum
CNS: Conscious proprioceptive deficit, hemiparesis, head/intention tremors/hypermetria
PNS: usually only signs are head tilt and dysequilibrum. Sometimes signs of facial nerve paralysis (paresis/paralysis of the eyelids, lip and ear) reduced or absent tear production
Treatment of head tilt secondary to otoconia/otolith
- Supportive care and time: Will improve over days to weeks = Fluid and assis feed if not eating!!
- Purposeful head movement - Modifier Epley maneuver (will help move otolith out of the canal)
- +/- Antibiotic (possibly) , Meclizine, midazolam, Meloxicam
E. cuniculi clinical signs
Chronic degenerative disease
Mentation change, lethargy (cerebrum)
CP deficits, hemiparesis, head tremors, hypermetria (cerebellum)
