17
Q

Aborted fetuses may be alive

A

Advanced pregnancy (>50 days)

18
Q
  • Shorter, but effective treatment

A

Mid-pregnancy (30-40 days)

19
Q

Q

What are the reasons why the use of “mismate shot” (ECP) is not recommended?

  • Increased risk of bone marrow suppression
  • Increased risk of pyometra
22
Q
  • Begin after day 35 gestation
    - If > day 50 gestation - live, nonviable pups delivered
  • Inexpensive
  • Preserves future fertility
  • 80% effective
A

Dexamethasone (Glucocorticoids)

23
Q
  • Stronger dopamine receptor (D2) agonist
  • Dose: 5 μg/kg PO SID x 5 days
    - Compounding often necessary
  • Minimal side effects (vulvar discharge)
  • No impact on fertility
  • Used with PGF2a
A

Cabergoline

24
Q
  • Veterinary compound approved in Europe
  • Progesterone Blocker
  • Two 10 mg/kg injections
    - SQ 24 hours apart
  • Fetal death within 5 days of treatment
    - Rare chance of treatment failure
    - Ultrasound needed to ensure efficacy
    - If still pregnant -> repeat injections
  • Can be used during “early” or “late” pregnancy
