Hydrallantois and hydramnios Flashcards
hydrallantois
- gross accumulation of fluid in allantoic sac
- 90% of bovine hydrops cases
- d/t placental dysfunction
- clear, watery, amber fluid
- greatly extended abdomen on both sides
- on rectal exam, can just find fluid (50-70 gallons at times)
- usually cannot palpate fetus or placentomes
hydramnios
excess of amniotic fluid
Fetal hydrops
- serious fetal condition
- abnormal accumulation of fluid in 2 or more fetal compartments, including ascites, pleural effusion, pericardial effusion, and skin edema
Roughly how many placentomes does a cow have?
120
Bloat is commonly only on the ____ side; while hydrallantois is _______ sides.
left; both
T/F: Joints can give out due to the amount of swelling.
True
Bovine andramnios
- 10% of bovine hydrops cases
- anomalous fetus- lack of swallowing reflex
- syrupy, viscid fluid
- may not be noticed until parturition
Treatment of Bovine hydrops
- Slaughter
- Induced abortion by prostaglandin and/ or dexamethasone
How does dexamethasone lead to an induced abortion?
Causes calf stress that leads to parturition
Procedure with Induced abortion
- put cow in box stall where she can be watched and give prostaglandin and/or dexamethasone
- check on every 12 hrs = feeling for when cervix is dilated
- Once dilated, puncture fetal membrane to release fluids (Keep mouth closed!)
- After that point, check until dilated enough to deliver calf -> often will be a small, dead calf
Is a C-section a good way to treat bovine hydrops? Why or why not?
It is not a good way to treat bovine hydrops.
Walls of uterus are super stretched d/t amount of fluid and will not stitch back together well.
Also, the amount of fluid that will be pouring out could get into the abdominal cavity, causing further problems
