How do you treat uterine artery hemorrhage post-foaling?

Aminocaproic acid

6

What is the MoA of aminocaproic acid?

Blocks activation of plasminogen to plasmin (clot stabilization)

7

What are clinical signs of uterine artery hemorrhage?

Recent foaling, low PCV, tachycardia

Caslick procedure + increase BW of mare

14

What is a Caslick procedure?

Horizontal sutures @ dorsal labia

15

What does pneumovagina predispose to?

Uterine infection

23

How do you diagnose endometritis?

Uterine cytology

24

What will you see on uterine cytology if the mare has endometritis?

High % neuts (+/- bacteria)

25

Why is a culture useless to dx endometritis in a horse?

So many commensal organisms

26

What organisms found in pre-ejaculate culture swabs have high assoc. of causing endometritis?

>800mg/dL

29

Which breed is predisposed to severe combined immunodeficiency (SCID)?

Arabians

30
