Castrationn & Ovariohysterectomy Flashcards
A surgical protocol includes
- an official procedure
- accepted or established code of procedure
- formal record of scientific experimental observations
- procedure for carrying out scientific experiment or a course of medical treatment
This stertilization reduces aggressive behavior & prevents roaming
elective sterilization
traumatic testicular conditions & injury (Indications)
- Testicular neoplasia
- Orchitis / Epididymis
In cats, the surgical site of castration is
always scrotal
In dogs, the most convenient surgical site of castration is
pre-scrotal
connected to parietal vaginal tunic
parietal peritoneum of abdomen (at deep inguinal ring)
Recumbency in feline castration
lateral recumbency
recommended incision site direction due to faster healing
straight vertical down
Risk in closed-type castration
ligation may be removed once pulled from the abdomen
Castration
instrument tie the _____ & _____
ductus deferens
testicular vessels
This technique is used when self-ligating
over-hand technique
Why dilate the incision site?
to facilitate cleaning
In this type of castration, parietal vaginal tunic is incised
open-type castration
This type of castration crushes tissues to facilitate ligation.
closed-type castration
Used to
(diagnostic)
— obtain biopsy
— diagnosis of foreign bodies
(therapeutic)
— internal hemorrhage
— organ rupture
— GDV
exploratory laparotomy
Recumbency of exploratory laparotomy and ovariohysterectomy
dorsal
Exploratory laparotomy RIGHT side
pylorus
descending duodenum
pancreas
ascending colon
cecum
right kidney
Exploratory laparotomy LEFT side
fundus
body of the stomach
spleen
descending colon
left kidney
always prepare this to protect the tissues from drying
moist laparotomy sponge
solution used to control contamination
warm sterile saline
Post-op complications of exploratory laparotomy
- dehiscense
- suture sinus formation
OHE is contraindicated in (2)
- estrus
- pregnant bitch
Incision site cuz it approaches the intestine, spleen & reproductive organs
mid-ventral incision
Where you shave (OHE)
xiphoid — pubis
animals that wakes up easily from anesthesia (may commit overdose)
younger animals
This drug must be given at the highest dose possible
morphine
the smaller the patient, the ___ tendency to overdose
greater
the larger the patient, the ___ the dose
greater
when there is neoplasm in scrotal area (dark colored scrotal sac); castration will be performed in conjunction with other surgical prcedures
scrotal ablation
Breed of dogs sensitive to thiobarbiturates
greyhounds
animal sensitive to:
1. morphine
2. meperidine
felids (cats)
In this animal
inhalation anesthesia — preferred
isoflurane — anesthetic choice
avian (birds)
This animal is at greater risk with general anesthesia and respiratory depression is common
swine (pigs)
In this animal
— general anesthesia is not suitable
— head should be lower than the neck
— intubation will prevent aspiration pneumonia
ruminants
This animal
— requires a chute
— local anesthesia for hoof & leg exams
—Major GA for major surgeries
— requires intubation
horses
complications in open-type castration
- self-mutilation
- scrotal hematoma
- local cellulitis
- abscess formation
