High Fiber
No Grain
Grass hay ad lib (NOT ALFALFA)
Fresh leaf greens

High Protein and Calcium
Doesn’t help grind teeth

Vitamin C Deficiency

T/F: When dealing with a dental abscess in a guinea pig, it is important to close the abscess after surgically debriding it to make sure bacteria doesn’t get into the area again.
False
We leave it open by “marsupializing” or packing it with antibiotic gauze/honey
For supportive care when dealing with a Guinea Pig who had a dental abscess, we will give meloxicam for pain, cisapride to aid motility and antibiotics for possible infection. How often do we syringe feed to ensure the Guinea Pig is eating?
QID
4 times a day
Ileus is usually a secondary problem in Guinea Pigs. What are some problems that can lead to ileus?
Post-Op

Sounds like bloat and at this stage of bloat there is a high mortalitiy rate.

Decompress with tube/aspiration
PARENTERAL Abx
Bupernorphine
Fluids (IV/IO/SQ)
Famotidine
