Preg and Abortion Flashcards
when to monitor in pregnancy
scan at 15d and 30d
*optional at 42d, 60d, 120d, 7m, 10m
what do you measure of scanning?
Combined Thickness of Uterus and Placenta (CTUP)
clinical signs of complications
colic
discharge
abdominal swelling
premature mammary growth
systemic illness
Early Embryonic Death is before __d
45
ventral edema
can be normal late in gestation
can be secondary to issue
ventral swelling +/- colic may be from ___ tendon rupture
prepubic
management for ventral hernia/prepubic tendon rupture
box rest
support
analgesia
reduce roughage
which is more concerning: hydrops amnion or hydrops allantois
allantois (happens faster. tx = abortion)
a low grade intermittent colic during preg might indicate
uterine torsion
tx for uterine torsion
roll under GA
induce if at term
causes of infectious abortion
EHV-1
EVA
placentitis
when is EHV abortion usually
last third
when during pregnancy should you vax for EHV-1 to reduce risk of abortion
5, 7, 9 mo
EVA transmission
AI, stallion
what causes placentitis
ascending bacterial infection
(S. equi zooepidemicus, E. coli, Klelbsiella, Pseudomonas)
how to dx placentitis
CTUP increase
fluid appearance
tx for placentitis
AB
altrenogest (to support pregnancy)
NSAIDs
placental insufficiency
associated with older mares, twins
leads to lack of nutrition for fetus
does twins lead to abortion
yes. 30% before scan.
or at 8-10mo no warning
how to terminate one of the twins
- manunal crushing before d30
- transvaginal aspiration of smaller one
- compression against pelvis d55-75
- cervical dislocation at d60-70
