6. II-Clinical classification of colic
1- Spasmodic colic
2- Flatulent colic
3- Obstructive colic
4- Specific colic due to outside
obstruction of bowel :
e.g. Volvulus; invagination; torsion;
strangulated hernia; scrotal,
diaphragmatic & umbilical hernia.
7. 1-Spasmodic colic
Definition :
It is a severe attacks of abdominal
pain caused by increase peristaltic
movement of the intestine,
characterized by:
intermittent fits of colic, rapid course
(short duration) and favorable
prognosis.
8. Etiology
(1) Drinking cold water when horse is hot
and sweat after work.
(2) Exposure of the body to external cold or
wetness.
9. Symptoms
(1) It occurs suddenly in the form of
fits of colic, each fit lasts from 5-15
minutes (short attacks).
during attack the animal kicks at the
abdomen, lies down on the ground
and rolls with violence .
10. but often rise again after rolling.
(2)There is slight increase in body
temperature, respiration, pulse &
congested mucosa.
(3) An increases in the peristaltic sound.
(4) Defecation occurs at short intervals and
the feces may be semisolid or fluid.
11. (5) Frequent passage of small quantity of
urine.
(6) Local or patchy sweating on back,
gluteal region, brisket & hindleg region.
(7) Horse may looks at the flank region
towards the site of colic.
(8) After the attach, the horse look normal
till second fit.
13. Treatment
(1) Give intestinal sedative and
antispasmodic drugs
R/ Atropine sulfate 4-6 ml 1%IM or IV.
R/ Anlagen 10 ml/100KgBW injected IV
(2) Rectal enema using warm water
and soft soap to stimulates and
regulates peristaltic movement of the
intestine and consequently relief pain.
15. Etiology
(1) Feeding on large quantities of highly
fermentable green feed such as
barseem.
(2) Ingestion of spoiled or moldy food or
grains, which has tendency to swell.
(3) Sudden change in the ration.
(4) Atony of the bowel.
(5) Obstruction of the bowel by sands.
16. Symptoms
(1) Sudden attacks of
continuous abdominal pain.
(2) Abdominal distension
(especially in the right flank).
(3) Cecal percussion gives
tympanic sound
17. (6) Congested mucosa, increase of
pulse & respiration, with moderate
to severe dyspnea.
(5) Affected horse may roll and
paw violently and lies down very
carefully.
(7) Small amount of feces may be
voided.
19. Treatment:
(1) Apply massage externally in flank
regions and internally through the
rectum using the hand.
(2) Rectal enema
(3) Purgatives:
Oral liquid paraffin 2-3 liters by
stomach tube
20. (5) Non steroidal anti-
nflammatory drugs:
Finadin
(6) Antifermentive such as
formaline solution, 10-20 ml
dissolved in 2 liters of water
given per os.
22. 3-Obstructive colic
(Colic due to impaction of the intestine)
It occurs when the large intestine
remains impacted with undigested food
material causing partial obstruction,
colic, depression & anorexia.
27. Etiology
(1) Overfeeding of grains or coarse food
rich in cellulose and bran for long period.
(2) Ingesting food materials, which contain
large amounts of mud or sand.
(3) Sluggish intestinal peristalsis
especially in old debilitated & or draught
horses.
(4) Greedy feeding & defective teeth.
28. (5) Obstruction of the intestine or natural
opening by large foreign bodies or parasite.
(6) Inadequate water intake or green food.
(7) Enterolith, fiber balls, hairball.
(8) Encephalitic (equine rectal paralysis).
29. Colic may be due to
(1) Impaction of the small intestine.
(2) Impaction of the colon.
30. [1] Impaction of the small
intestine
Causes:
It occurs due to accumulation of sand
in the small intestine (sandy colic) or
large number of parasites (Ascaris).
31. Symptoms
(1) The symptoms varies according to the
location of impaction:
when the duodenum is affected, the
symptoms occurs after feeding within few
hours.
when the ileum is affected symptoms
appear after several hours.
(2) Restlessness and beats the ground
with the forelimbs.
.
32. (3) In severe attacks the animal lies on the
ground and rolls
(4) During urination the animal throw the
hindlegs backward and outward and urine
comes out at intervals.
33. [2] Impaction of the colon
It is due to
accumulation of
undigested
materials in the
colon.
The large colon is
the most common
seat of impaction in
horse.
34. Symptoms
(1) Subacute colic which occurs slowly,
started with dullness and abdominal
discomfort, the animal looks at the flank
and kicking its belly.
(2) Constipation, Feces are passed in
small amounts, hard in consistency and
covered with thick & sticky mucous.
(3) Intestinal sound are absent or much
decreased in intensity.
35. 4) Moderate increase in pulse but the
temperature & respiration are normal.
(5) Rectal palpation revealed balloon
shape colon impacted with fecal mass.
(6) Dehydration, thirst, anorexia occur
with constant effort to urinate.
37. 1-Case history
A-How sever has the pain been?
B-When did the horse last defecate?
And what was the character of the
feces?
C-Has the horse shown specific
behaviour such as playing with water?
D-Could the horse have gaine access
highly fermentable food?
38. 2- Examination of pulse:
The heart rate and the character of
pulse are important in determining the
degree of severity of colic.
Rates greeter than 80 bpm should be
considered the result of sever lesion or
disease
39. 3- Examination of M.M
In simple dehydration the oral mm is
slight bluish but in sever dehydration it
becomes brick red or cyanosed. In
sever cases it becoms pale blue-grey
color.
40. 4- Auscultaion of
abdomen
Site: the caudal edge of the last ribe
from the paralumber fossa to ventral
abdomen on both right and left side:
Deacrease or absence of intestinal
sounds in case of clonic impaction
NB:
Gas/fluid interface sounds cause by the
movments of the horse should not be
mistaken
41.
42. 5-Rectal examination
In lare colon impaction is characterized
by an enlarged, firm, filled viscous
located on the pelvic floor
43. 6-Abdomenocentesis
Analysis of peritoneal fluid reflects the
changes. More than 500 white blood
cells/Ul. increase Of protein and RBcs
in colonic impaction & strangulation.
44. 7-Laboratory ex
PCV and Total plasma protine are used
to detrmine the hydration state of the
animal.
Electrolyte and acid base balance.
50. (2) Laxative:
per os or direct into the cecum by long
needle as liquid paraffin or mineral oil
or lin seed oil (2-3 liters).
51. (3)Fluid therapy:
R/Saline (0.09%Na Cl) 5-6LI/V
(4) Rectal enema :
using warm water and soft soap or lubricant.
According to the the degree of dehydration
(5) Parasympathetic drug:
R/Neo-stigmine 1 amp/70 Kg BW

52. Meconium impaction in
foals
Meconium is the first fecal material
produced in the uterus by a newborn
foal.
It is Composed of cellular debris,
amniotic fluid and intestinal secretions.
53. It is normally passes within 30 minutes to
two hours after birth.
It is dark brown and forms small balls,
but in meconium impaction it becoms dry
and hard.
54. Causes
lack of oxygen at birth may affect
intestinal motility.
Dehydration may also effect the
passage of fecal material.
A narrower pelvis in male foal may
predispose it to impaction.
55. Abdominal pain
manifested by tail
swishing and
restlessness
Reduced attempts
to nurse
recumbency and
violent rolling
Clinical finding
60. [1] Embolic colic
(Verminous aneurism)
It is disorder in the intestine due to
the presence of larvae of strongylus
vulgaris in the anterior mesenteric
artery of the horse, causing
aneurisms, emboli and thrombi of the
mesenteric artery and its branches.
61. Clinical symptoms
It is characterized by intermittent
and attacks of colic which
occurs suddenly during work as
in spasmodic colic, beside that
the feces are bloody ¶sitic
eggs are present in fecal
examination
65. CausesCauses
(1) Severe attack of colic.
(2) violent movements, or sudden fall of
the animal.
(2) Injections of large dose of
parasympathetic drugs
(3) Heavy infestation with parasite
(Ascaris) cause irregularity in peristaltic
movement of the intestine .
66. SymptomsSymptoms
(1) Peracute abdominal pain, .
(2) Profuse sweating due to fatigue & pain.
(3) Initially temperature is elevated,
terminally becomes subnormal.
(6) Clean rectum by rectal palpation
(7) Short course, death within 48 hours.
69. [[33] Intestinal strangulation] Intestinal strangulation
It occurs when a lope of the intestine
passes through a natural or artificial
opening in the peritoneum as in case of
inguinal hernia in stallion. Also in case
of pedunculated tumour which cause
strangulation.
Symptoms: as torsion.
Treatment: Surgical.
