Exam 1: Bovine Dystocia Management Flashcards
Amniotic fluid stained green with meconium is indicative of
a calf that is stressed, hypoxic, and needs OUT
Describe proper chain placement on the legs when
pulling a calf
Loop above and
half-hitch below
the fetlock joint
Connecting chain should be on TOP of the legs
2 people pulling on a calf exerts ______ PSI
while a calf-jack can exert 2,000 PSI
400
If the calf cannot come out, stretch the vulva. If that does
not work, can do this
episiotomy
Where do you perform an episiotomy?
at 10’ or 2’o clock
NEVER perform an episiotomy at 12’oclock.
Why?
Can cause a
rectovaginal fistula
When pulling a calf,
traction on both forelimbs simultaneously often
results in
shoulder lock
How do you prevent HIP lock when pulling a calf?
Rotate the calf as the head emerges
from the vulva (because the fetal hips are the widest part)
What choices do you have if delivery with traction (pulling)
is not possible?
C-section
Fetotomy
Why is a c-section not necessarily the best option
for a calf that cannot be pulled?
Potential impact on future fertility of the cow.
Anasarca calves should always be removed
by
C-section!
NOT a candidate for fetotomy
What do you choose to remove a calf
if the uterus has contracted around it?
C-section!
NOT a candidate for fetotomy- need adequate space
The most common type of fetotomy
partial fetotomy
After fetotomy, cows should be given fluids, calcium,
and antibiotics along with
which 2 ecbolics?
Oxytocin, Lutalyse
90% of C-sections are due to which 5 reasons?
Fetal oversize- emphysematous changes
Cervical incomplete dilation or closure on dead fetus
Uterine torsion that cannot be reduced
Fetal deformity (schistosomus reflexus)
Errors of fetal PPP
