Flashcards in Colic - Decision Making Deck (11)
What can distend the abdomen of horse? And what may cause these?
Gas, fluid, Ingesta
Anatomical, mechanical or functional obstructions
What types of mechanical obstruction are likely to cause a strangulating colic?
What things can cause ischaemia of the gut in horses?
Thrombosis - parasites (stronglylus vulgaris), coagulopathies, DIC
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
What are the causes of strangulating lesions?
Volvulus around mesenteric root
Epiploic foramen entrapment
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.
Why is it important to refer SI causes of colic?
Most of the causes of SI colic will require surgery or intensive medical treatment.
Which cases of colic should be considered for referral?
Lesions requiring intensive medical treatment
What should be discussed with the owner prior to referral?
Circumstances (e.g. age of horse)
Willingness to surgery?
What signs may indicate the need for referral?
poor response to analgesia
severe abdominal distension
SI lesion signs
Signs of strangulating lesion
