Cards

Term
Nasogastric intubation
Definition
used in horses to administer meds, release gas/fluid buildup, treat colic (m.c.), treat choke
Term
Tube
Definition
Clear w/ flared end for attaching funnel or pump; smooth, beveled end; make pliable w/ bucket of warm water
Term
Passing the nasogastric tube
Definition
Lube end, pass tube into ventral nasal passage, flex head, chase swallow reflex
Term
reflux
Definition
fluid that accumulates in horse stomach
Term
If tube is in esophagus...
Definition
Slight resistance to it going down
Visualize/feel in esophagus
Negative pressure (esophagus will collapse)
Ingesta aroma
Audible GI sounds
Term
If tube is in trachea...
Definition
Hear/feel respiratory noise
No resistance going down
Shake trachea, hear tube rattling
No negative pressure (you'll just get more air)
Coughing UNRELIABLE, until you put water down the tube
Term
Removing tube
Definition
Blow tube empty
Kink end to prevent aspiration
Slowly remove w/ head in normal position
Term
Orogastric intubation
Definition
used in cattle and other animals to administer meds, release gas/fluid buildup, obtain rumen sample, treat choke
Term
Passing the orogastric tube
Definition
use a speculum (Frick, harp, etc)
restrain head
lube end
chase swallow reflex
Term
Rumen Fluid Analysis
Definition
Establishes cause of indigestion
Used for transfaunation
Term
3 Collection Methods for Rumen Samples
Definition
Percutaneous puncture
Stomach tube
Specialized device
Term
Percutaneous puncture (Rumen Sample)
Definition
Can only collect fluid, use lower 3rd of abdomen on left side to obtain sample from ventral rumen sac
Term
Stomach tube
Definition
Use speculum
Saliva may contaminate sample
Allows collection of ingesta as well as fluid
Term
Saliva
Definition
Contaminates rumen samples by diluting the sample and altering pH. You can prevent by covering the end of the tube w/ a piece of rubber glove
Term
Fluid color
Definition
olive/brownish green
brownish yellow w/ grain diet
Milky gray = acidosis
Blackish green = GI stasis
Term
Fluid consistency
Definition
Slightly viscous
Saliva contamination will make more viscous
Term
Fluid Odor
Definition
Normally "aromatic"
Less prominant odor = inactive flora
Sour smell = acidosis
Putrid = GI stasis
Term
Normal pH
Definition
5.5 - 7.0
concentrate - roughage
Term
pH <5.5
Definition
rumen or lactic acidosis
Term
pH >7.0
Definition
anorexia, salivary contamination, urea toxicosis
Term
ph <5.0
Definition
complete die off of protozoa
Term
Bacteria populations in rumen
Definition
Gram negative should predominate, overconsumption of grain leads to over population of gram positives.
Term
Sedimentation/Flotation rate
Definition
4-8 min. A faster time may be caused by many abnormalities.
Term
Abdominocentesis Indications
Definition
Colic (Abdominal crisis/Acute abdomen)
Peritonitis
Wt. Loss
Chronic GI disease
Ascites
Term
Abdominocentesis Technique
Definition
Percutaneous puncture
Stainless steel teat canula/bitch cath
Ventral aspect of abdomen just adjacent to midline
Avoid sq vessels
Use lavender top tube
Term
Percutaneous Puncture (Abdominocentesis)
Definition
Simple, but risk intraluminal sampling
Term
Stainless steel teat canula/bitch cath
Definition
Necessitates local block and incision, decreases intraluminal sampling
Term
Transudate
Definition
TP <2.5 g/dl, nucleated cells <1000/ul
Term
Modified Transudate
Definition
TP <3.0 g/dl, nucleated cells <5000/ul
Term
Exudate
Definition
TP >3.0 g/dl, nucleated cells >5000/ul
