Flashcards in Colic - Decision Making Deck (11):
1

What can distend the abdomen of horse? And what may cause these?

Gas, fluid, Ingesta
Anatomical, mechanical or functional obstructions

2

What types of mechanical obstruction are likely to cause a strangulating colic?

Volvulus
Torsion
Incarceration

3

What things can cause ischaemia of the gut in horses?

Strangulation
Thrombosis - parasites (stronglylus vulgaris), coagulopathies, DIC

4

What are the causes of non strangulating lesions and their treatment plans?

Spasmodic colic - spontaneously resolves
Impaction - fluid, worst cases need surgery
Displacement - will resolve but may need surgery at some point
Enteritis/Ileus - reflux will require relief (NGT) and intensive treatment
Typhlocolitis - diarrhoea => intensive treatment
Peritonitis - intensive treament/surgery

5

What are the causes of strangulating lesions?

Volvulus around mesenteric root
Strangulating Lipoma
Epiploic foramen entrapment
Inguinal/Scrotal Hernia
intussusceptions
Diaphragmatic hernia
Mesenteric rent

LI
Torsion
Intussusception

6

How can a SI vs. LI lesion be distinguished?

SI - will see reflux
- palpable SI on rectal/ultrasound findings of distension
LI - (abdominal distension)
- Impaction/gas distension rectally palpable
- Displacement palpable
- Usually no reflux.

7

Why is it important to refer SI causes of colic?

Most of the causes of SI colic will require surgery or intensive medical treatment.

8

Which cases of colic should be considered for referral?

STRANGULATING LESION
SI lesions
Lesions requiring intensive medical treatment
Non-resolving impactions
Recurring/undiagnosable

9

What should be discussed with the owner prior to referral?

COST
Circumstances (e.g. age of horse)
Insurance
Expectations
Willingness to surgery?

10

What signs may indicate the need for referral?

Mod/Severe pain
Recurrent pain
poor response to analgesia
CV compromise
severe abdominal distension
SI lesion signs
Signs of strangulating lesion

11

What sorts of things can determine whether a colic is medical or sugical?

HISTORY
-Pain
-feeding
-response to analgesia
CV FITNESS
GI SYSTEMS
-Borborygmi
-passing of faeces
NGT/RECTAL
-Reflux
-Distension of SI?
TREATMENT RESPONSE
-Amount needed
-Reccurance
