Colic Case Flashcards
pathophysiology of colic (5 general steps)
abdominal disturbance
endotoxemia
multi system organ failure
disseminated intravascular coagulation
death
how does abdominal disturbance lead to endotoxemia
third spacing of fluid and/or gut ischemia –> dehydration –> decreased intestinal perfusion –> tissue hypoxia –> tissue death –> endotoxemia
what is the main type of bacterial toxins responsible for endotoxemia
gram negative bracteria
medical colic
fixed medically
mild to moderate pain that responds to analgesia
treated in the field
less serious and expensive
surgical colic
requires surgery to fix
moderate to severe pain that is not responsive to analgesics
more serious and expensive
capillary refill time: definition, determined by, normal values
time it takes for mucous membranes color to return
determined by peripheral capillary blood pressure
1-2 seconds
CRT is an indicator of (2)
peripheral perfusion
hydration
CRT above 1-2 seconds is indicative of
dehydration
rectal exam findings for colic
large bowel is gas distended
tight bands/taenia
normal medical management for colic (3)
xylazine
butorphanol
banamine
diagnostics/colic work up: field and hospital
physical exam, rectal exam, nasogastric intubation
clin path (PCV, TS, CBC/chem, venous BG)
trans abdominal u/s
abdominal rads
abdominocentesis
gastroscopy
expected abdominocentesis result: colic
turbid dark yellow to orange peritoneal fluid
WBC and TP elevated
3 questions to ask for differential diagnosis
medical or surgical
strangulating or non strangulating
small intestine or large bowel/colon
large colon volvulus definition
twisting of segment of bowel along mesentery
how to treat dehydration (2)
IV cath
fluids + volume expansion
