1
Q

What fluids do you want to use if there is a metabolic acidosis?

A

LRS or 5% HCO3

Lactate is transformed to HCO3- in the liver

2
Q

What two species are most prone to developing adhesions?

A

humans and equines

Try to minimize manipulation of the bowels!

3
Q

After repairing intussusception, what are the most common post-op complications?

A

ileus, peritonitis

4
Q

What is the post-op survival rate for an intussusception in cattle?

A

43%

5
Q

What fluids do you want do use if there is a metabolic alkalosis?

A

LRS or NaCl

6
Q

T/F: With medical and surgical intervention of hemorrhagic bowel syndrome in cattle, the prognosis is good

A

False

Even with medical and surgical intervention, the prognosis is poor (70% death rate)

7
Q

Identify the intussusceptum:

A
8
Q

Most likely diagnosis?

A

perforated abomasal ulcer

9
Q

What surgical approach is typically used to resect an intussusception in ruminants?

A

Right flank celiotomy

10
Q

What do you expect to see on abdominocentesis with an intussusception?

A

Normal

Because the necrotic segment is contained inside the normal segment

11
Q

The prognosis for survival in intestinal volvulus depends on:

A

the duration of the obstruction and the viability of the bowel

12
Q

What species did this come from?

A

Cow

Note the increased fat in the mesentery

13
Q

What is the most likely cause of hemorrhagic bowel syndrome in cattle?

A

Clostridium perfringens type A

14
Q

When would you choose to do a side to side intestinal anastamosis?

A

If you want to create a large lumen or are working on bowel of different diameters

15
Q

What is/are the most common location(s) for intussusception in horses?

A

mid-jejunum, ileocecal, cecocolic

16
Q

Identify the intussuscipiens:

A
17
Q

What is the post-op survival rate for a cecocecal or cecocolic intussusception in horses?

A

27-45%

However, post-op survival rate for a SI intussusception in horses is guarded

18
Q

Most likely diagnosis?

A

fat necrosis in mesentery

Fat necrosis in mesentery can end up as obstruction of the SI Usually euthanized because multiple blockages

19
Q

What does an intussusception look like on ultrasound?

A

Like this:

20
Q

What is/are the most common location(s) for intussusception in cattle?

A

distal jejunum and proximal ileum

21
Q

What do you find on rectal exam in a cow with intussusception?

A
  • Gas filled loops
  • Firm mass
  • Tight mesentery
  • No feces
  • Mucus and clotted blood
22
Q

T/F: Young animals are more predisposed to intussusception than older animals

A

True

  • Young are predisposed - more susceptible than old
    • If <6mo and have GI obstruction, need to consider intussesception
    • Have more enteritis (increase motility), more active
23
Q

T/F: Hemorrhagic bowel syndrome is an acute enteric disease most frequently seen in beef cattle

A

False

Hemorrhagic bowel syndrome is an acute enteric disease most frequently seen in dairy cattle
