Basics of Female Repro Tract Flashcards
indications for ovariectomy
tumor - GTC
prevent estrus
ovarian abscess/hematoma
repro manipulation
What are some considerations for pre-ovariectomy surgery?
temperament
size
uni/bilateral?
equipment
what is involved in the colpotomy
vag incision forward in cervix over to the ovaries.
Best to give topical anesthetic
then the chain ecraseur to cut out.
Don’t suture vaginal wall closed
give NSAIDs, AM, and keep standing for 4-5 days.
Approaches to the ovariectomy
Flank approach - standing or lateral.
Ventral approach - midline or paramedian (people do the lateral but there have been lots of complications)
What is involved in the modified grid?
incision through the skin
blunt dissect the muscle bellies along their axis
make the incision size a little bigger though
the paramedian of ventral ovariectomy approach is better if…
massive ovary to deflate and then pull out. or just need for the size to get out.
What is a common mistake with the lateral flank approach?
we will automatically make the incision lower down on the flank because of the position
complications of ovariectomy
hemorrhage evisceration peritonitis CV derangements wound (flank) dehiscence myopathy/neuropathy from GA
Contra-indication to C-sections
if they aren’t ready to be born yet duh!
Reasons for hysterotomy (C-section)
ELective -small pelvic canal -vaginal mass -reucurring cervical laceration Emergency - dystocia -full-term uterine torsion
what to consider before doing hysterotomy (C-section)
fetal maturity
induce only after 1st stage of labor
have personel to deal with the foal
What is important for the life of the mare when doing a hysterotomy (C-section)
that nothing from the uterus gets into the abdomen!!
For the surgical procedure of hysterotomy (C-section), how do you go about closing?
it will bleed like crazy
stop the bleeding with the roundy-roundy-on each side of the incised uterus
then once stopped, peel some placenta away to let it pass on it’s own
close with a double inverting
finish up
hysterotomy (C-section) complications
colic hemorrhage retained placenta peritonitis laminitis uterine adhesions
Post-op hysterotomy (C-section) care:
Fluids AM NSAIDs - pain and anti-inflamm Fluids Oxytocin
CLinical signs of uterine torsion
Low grade colic
(have on DDx if pregnant)
need rectal to know
Approaches to uterine torsion
Rolling +/- plank - need confidence and muscle. not done
standing flank - blind, but gravity
ventral midline - fill w/ water to help. also can explore a lot
Complications of uterine torsion
uterine necrosis
abortion
hemorrhage
GI trauma
Prognosis to mares and foals
75% to mares
live foal 55-70%
whats the worry with fixing the uterine prolapse?
may have torn and is occluded but now will hemorrhage when fixed
Also, the bladder will be blocked so when corrected, will be peed on.
Definition of urovagina
urine in the vaginal fornix
what does urovagina cause?
vaginitis, cervicitis, decreased fertility
predisposing factors to urovagina
tipped cervix and uterus so things drain in
effects of urovagina on repro
sperm doesn’t like urine
