Equine 4 Flashcards
what is false colic?
pain from non-GI structures.
IE: laminitis, peritonitis, cholangiohepatitis.
signs of colic
-Flank watching
-Pawing
-Bedding disturbance
-Lying on back
-Rocking horse stance (pleural or peritital pain)
-Lip curling, teeth grinding
4 main causes of abdominal pain (colic)
Distension!
Inflammation
Ischaemia
Stretching of mesentery
clinical eval of colic case should look for obstruction to ___ or ____
obstruction of bowel ingesta
obstruction to blood flow
how to detect obstruction to bowel?
Rectal or
US or
Passing gastric tube (lots of reflux = distal obstruction)
Obstruction to blood flow might be caused by
Strangulating lipoma
SI volvulus
Colon torsion
*therefore, often accumpanied by ingesta obstruction
young horses are more susceptible to which cause of colic
intusussception
recently folaed mare horses are more susceptible to which cause of colic
colon torsion
an elevated rectal temp indicates
inflammatory/infectious
tachycardia indicates
-reduced venous return
-endotoxaemia
*early indicator of strangulation, NOT pain
increased RR indicates
pain,
acidosis,
severe distension
abdominal auscultation decreased sounds indicates
localized = caecal/colon impaction
generalized = endotoxaemia
*listen to all 4 quadrants
what to do if you feel distended loops of SI
refer
what do you feel w impaction of pelvic flexure
doughy mass within pelvis (primary)
corrugated mass (secondary)
causes of SI distension
-strangulating obstructions
-ileus
-impaction
