Abomasal Disorders: Ulcers Flashcards
1
Q
Types of abomasal ulcers
A
Erosion only (1)
Bleeding (2)
Perforating and local peritonitis (3)
Perforating and diffuse peritonitis (4)
2
Q
Abomasal ulcers etiology
A
Stress? Diet? - High grain - Corn silage Lymphosarcoma Chronic abomasal displacement NSAIDs?
3
Q
Abomasal ulcer epidemiology
A
Uncommon (<1% annual incidence)
- Hospitalized camelids = high risk
All types of cattle
Rare in small ruminants
4
Q
Abomasal ulcer CS
A
Erosion only:
Decreased appetite
Abdominal pain
Bleeding: Decreased appetite Abdominal pain Anemia Melena
Perforating with peritonitis:
Decreased appetite
Abd pain
Fever
Perforating w/ diffuse peritonitis: Anorexia Abd pain Dehydration Depression Fever Abd distension (peritoneal fluid)
5
Q
Abomasal ulcer Tx Adult
A
Diet - more forage Environment: - Reduce stocking density - Segregate by age - Heat stress abatement Symptomatic/ supportive Tx: - Blood transfusion prn - IV fluids prn - Abx prn NO NOSAIDs/STEROIDS! Oral antacids limited value - Magnesium hydroxide (Carmilax) - Mg oxide H2 antagonist/proton pump inhibitor - Pantoprazole . 1mg/kg IV SID or 2 mg/kg SC SID . Cost ~$12/100lb BW (IV dose)
6
Q
Abomasal ulcer tx Calf
A
Oral antacids - Maalox: 25-50mL PO BID-TID Gastric protectants - Kaolin-pectin soln . 90-180mL PO BID-TID . =/= Kaopectate (bismuth subsalicylate) H2 blockers - given orally Increase frequency of feeding - BID -> TID - QID - Keep total daily volume the same
7
Q
Abomasal tympany/Abomasitis basics
A
Calves, kids. lambs
>2wk
Typically bottle fed
8
Q
Ab. Tympany/Abomasitis pathogenesis
A
Delayed emptying - High osmolarity soln decrease emptying rate . Accelerated milk replacer - Mix correctly - Free choice water Large volume milk ingested - 2x daily feeding - Calves removed from dams (processing) Accumulate ingesta in abomasum - Bacterial overgraowth -> gas production . C. perfringens type A?
9
Q
Abomasitis CS
A
Acutely off feed - No preceding diarrhea** Lethargic/depressed Colic Later stages - Abd distension - Slosh in R cr abd (gas and fluid in abomasum) - Dehydration Death in 24-36h w/o prompt Tx
10
Q
Abomasitis Tx
A
PPg -10mL PO -5-10mL SC (44 KIU/kg) sid C. perf type C and D antitoxin -10mL PO -10mL SC
11
Q
Abomasitis Prevention
A
Feeding mgmt
C perf type A toxoid?
12
Q
Abomasitis Tx continued (not gone over)
A
Deflate abomasum - Only if severe distension . Compromised resp . Severe distension can damage abomasum - Dorsal recumbency, use 14g 2 inch needle - Risk of peritonitis IV fluids prn Feed small volume milk (~1L) after crisis passes
