Cow Part 2 Flashcards
who is uterine torsion most common in?
dairy cows
brown swiss especially
does carrying twins protect a cow from uterine torsion?
yes
how can you treat a uterine torsion?
manual correction per vaginum
detorsion rod
rolling and “plank in the flank”
surgical correction
what is the more common hydrops of fetal membranes?
hydrops of allantois: 90%
is hydrops of allantois or hydrops of amnion rapid accumulation of fluid?
hydrops of allantois
how can you induce therapeutic abortion in days 7-150?
prostaglandin
how can you induce parturition?
corticosteroids
prostaglandin
both
how can you treat fetal mummification?
prostaglandin
what is a sequela to fetal mummification?
fetal maceration
when does uterine prolapse occur?
most immediately after calving
rarely after several days
what are the risk factors for uterine prolapse?
hypocalcemia
forced fetal extraction
flaccid uterus/gravity
what do you want to elevate the uterus to when fixing a uterine torsion?
level of ischial arch
what drugs are given to a cow after uterine prolapse?
calcium
oxytocin
antibiotics?
suture vulva?
what are the potential complications with uterine prolapse?
uterine rupture
uterine artery rupture
intestinal prolapse
re-prolapse (rare with proper replacement)
what are the risk factors for retained placenta?
hypocalcemia
selenium, vitamin A deficient
twins
premature calving/abortion
stress
is manual removal of the retained placenta indicated?
no- contraindicated
is intrauterine therapy for retained placentas recommended?
no
damages endometrium and precludes cow’s own defenses from working
when does uterine torsion occur?
late stage I-early stage II
torsions <180 degrees may present days-weeks without signs until labor begins
what treatment choice is best for a recumbent cow with uterine torsion?
rolling
can you palpate the fetus and placentomes in hydrops of allantois and amnion?
only in hydrops of amnion
what can be seen externally with hydrops of allantois?
severe abdominal distension: barrel-shaped
what can you give to induce abortion at 5-8 months?
prostaglandin and dexamethasone
when should you expect delivery after you give drugs to induce parturition?
40-50 hours
what risk is increased if you induce parturition?
risk of retained placenta
what can you give for an epidural?
5-7 ml 2% lidocaine for mature cows
can add xylazine
what is the prognosis of uterine prolapse?
good for life and fertility if promptly treated
rarely recurs
is there treatment proven to decrease duration of retention and improve fertility with a retained placenta?
no
why is intrauterine therapy for retained placentas not used?
milk residue/withholding issues
damages endometrium and precludes cow’s own defenses from working
