30
Until when do you lavage the abdomen with warm saline before closing?
Until what you're taking out looks like what you're putting in
31
What is the layer of strength on the abdomen?
External rectus shealth
32
What closure patterns can you use to close the abdominal cavity? Which suture types do you AVOID using?
Simple interrupted Simple continuous _Avoid:_ Chromic gut (inflammatory), Silk (inflammatorY), Vicryl Rapid (absorbs too fast), Polymerized caprolactam (granuloma formation)
33
What bites do you take when closing the abdominal fascia? How do you check if you have good bites?
5mm by 5mm Lift up on suture bite or place finger in incision and lift up
34
Why do you close the SQ tissue?
Relieve dead space Better skin apposition
35
What can you do as an alternative to a SQ closure? What migh this make unnecessary?
Intradermal/subcuticular pattern May not need to close the skin
36
Why are tension patterns counter-indicated for skin unless tension is present? What suture type and size is typically used to close the skin?
Tendence to **evert** the skin and thus dely healing 3.0 monofilament (absorbable or non-absorbable)
37
According to the *Veterinary Surgery* invited review *Making a Rational choice between Ovariectomy and Ovariohysterectomy in the Dog: A discussion of the benefits of either technique,* what is the preferred method of gonadectomy in the healthy bitch?
OVE (ovariectomy)
38
Why does OVE not predispose a patient to pyometra?
Because this condition is hormonally induced, removing the source (ovaries) prevents the disease
39
Why is spaying an animal a possible treatment for idiopathic epilepsy?
Estrogen decreases the seizure threshold
40
Why is spaying an animal a possible treatment for diabetes mellitus?
Progesterone blocks insulin receptors
41
Why is a spayed patient more prone to obestity?
Cycling estrogens decrease appetite Spaying reduces the metabolic rate A spayed animal requires fewer calories
42
Why can spaying cause urinary incontinence?
Estrogen affects the urethral sphincter mechanism
43
Which types of neoplasia occur at a higher incidence in spayed animals?
Hemangiosarcoma Lymphoma
44
T/F: A patient should always be prepped from xiphoid to pubis for an OVH.
True
45
Between which organs is the uterine body?
Colon and bladder
46
Which ligament is between the ovary and uterine horn?
Proper ligament
47
What prevents the ovary from being completely exteriorized unless it is broken?
Suspensory ligament
48
The ovarian arteries branch off of the \_\_\_\_\_\_\_\_\_. The right ovarian vein drains into the _______ while the left drains into the \_\_\_\_\_\_\_\_\_.
Aorta Vena cava Left renal vein
49
What type of suture, absorbable or non-absorbable, is preferred for OVH?
Absorbable ## Footnote *At Ross probably 2.0 PDS*
50
Why do you need to break down the broad ligament before making ligatures?
To minimize tissue in ligatures - more stable, secure
51
What are the signs of shock that you need to watch out for post-OVH?
Slow recovery Pale membranes Distended abdomen Decreased BP
52
53
Neuter or Castration? _1:_ Any sterilization procedure _2:_ Any pocedure in whcih an individual looses his testicles

True
55
Why does an orchectomy help prevent perineal hernias?
Testosterone weaknes pelvic muscles

57
Which surgical approach is indicated for testicular or scrotal neoplasia, but not for routine neuters?
Scrotal with ablation
58
In how may layers do you close the incision of a closed castration? What structure must you be careful to avoid?
