farm animals Flashcards
for beef quality assurance where should you keep all injections
keep all injections in front of the shoulder
SC and IM
no more than 10cc
where are the proper injections sites for BQA in cattle
-SC the triangle before jugular groove, prescapular, and under nuchal ligament
-IM smaller area, above the spine
what block is used for dehorning and where do you inject
cornual block
-injection is half way between the lateral cam thus of the eye and the base of the horn
for dehorning in cattle what is an addition thing you need to do for cows over 1 year old
additional ring block on caudal side of horn
-around base of horn
what blocks are used for dehorning in goats
cornual block (same as cattle) between the lateral canthus of the eye and base of horn
and
intratrocantar midway between medial canthus and medial horn base
what do you need to take precaution with when blocking goats?
toxicity
what block is the auriculopalpebral and where do you inject
-halfway between lateral canthus and base of the ear on zygomatic arch
-blocks motor to eyelids and orbicularis oculi muscle, used for easier exam of eye or proptosis of globe
NOT SENSORY BLOCK
what does the supraorbital nerve block block?
-blocks sensory and motor to the upper eyelid
-does NOT block orbicularis oculi muscle
-for lavage
what is the 4 point block
protect globe with finger
inject through conjunctiva
deposit lidocaine behind the globe within muscular cone
retrobulbar block
-going over the eyelid to deposit lidocaine behind the globe within muscular cone
Peterson eye block
-going behind the eye
how is the blood supply on the ear arranged in the goat and give the name
caudal auricular vein and artery
-arteries on either side with vein in middle
what is the vein used for ear
IV fluid therapy
what is the artery used for ear
arterial blood gas analysis
where is the injection site for excede in cattle
at the base of the ear
what is the torus liguae
normal structure at the base of the tongue that pushes food bolus onto the hard palate to squeeze liquids into esophagus
what is diastema
gap between premolars and canines
-allows safe passage of hand in the mouth
where does the esophagus lie relevant to the julgular vein
medio-dorsal to the juglar
at what 3 locations can you give a caudal epidural
-sacrococcygeal joint
-first intercoccygeal joint (better access)
-second intercoccygeal joint
when doing a lumbosacral epidural what are you blocking?
sensory and motor to caudal half of the body
epidurals are in the epidural space where there is no CSF and there is neg pressure
fact
if you go through the dura and get into the CSF, you are in the subarachnoid space and is called what/
spinal anesthesia
what are some indications for a caudal epidural
dysotica
c section
rectal prolapse
vaginal prolapse
uterine prolapse
when doing a lumboscaral epidural for a umbilical surgery what else would you have to do?
must do some local block cranial to umbilicus
where would you do a CSF aspirate
midline just caudal to a line connecting tuber coxae
what are the 3 techniques for a flank anesthesia
line block
inverted L
paravertebral block
what is the technique for a paravertebral block?
-proximal/dorsal
-distal/lateral (tip transverse process)
blocking nerves from T13 L1 L2
what are the landmarks for finding L1
you find the tuber coxae and cranial to that is L5 and then you count to L2 L1 T13
when doing a paravertebral block where is the nerve root located?
below the transverse process so you want to inject more volume below
