Caldwell TQs Flashcards
Indications for castration
- Eliminate masculine behavior
- prevent breeding
- pathologies (ing. hernia, orchitis/epididymitis, hydrocele/varicocele, testic. torsions/trauma, testic. neoplasia)
Optimal age of castration
1-2 yrs
When do the testes move to the inguinal canal?
270-300 days of gestation (descended @ birth)
True/False: when preping the equine P for castration, you should give tetanus prophylaxis?
True
Benefit of standing castration
Don’t have to wait for them to recover
In the surgical castration approach, what are the 2 parallel incision
- Parallel to the median raphe
- Incise skin, dartos, fascia
In which technique of castration is the parietal tunic incised?
Open
In which method of castration is the parietal tunic not incised?
Closed
In which technique of castration is the vaginal cavity not opened?
Closed
True/False: tearning does not help hemostasis
False
When castrating, which testicle do you start with (higher or lower hanging one)
Lower testicle first
How does the scrotal incision heal
open heal by 2nd intention
or
primary closure
How long does it typically take the open scrotal incision to heal
3 wks
Post op: how much stall rest? forced exercise?
Stall rest: 24 hrs
Forced exercise: 7-10d
When is frank blood coming out of the scrotal incision post op considered a problem
if unabated streaming of blood continues for 15-30 min post op
What is usually the source of hemorrhage post op (castration)
Testicular artery (vein has valves so not from there)
How do you tx post op castration hemorrhage
- Reclamp/emasculate cord
- pack inguinal canal w/guaze –> remove next day
- hemostatic agents (aminocaproic acid IV; Formalin IV)
- antibiotics
- transfusion/fluid therapy
- laparoscopic exploration/ligation
Evisceration is a surgical emergency….in which horses should you use caution while castrating to avoid this
Horses <6m
What is septic funiculitis
what causes it
Infxn of the spermatic cord
due to extension of scrotal infxn
Factors that may contribute to septic funiculitis
- improper scrotal drainage
- non-absorbable suture
- open castration
- chronic infxn/cirrhous cord
What is the most common type(s) of cryptorchidism
- complete –> testis & epididymis abdominally retained
- partial/incomplete –> epidiymis but not testes has descendend thru vaginal ring
