Pancreatitis Flashcards
What element is critical for zymogen activation?

Activation of which zymogen is critical for activation of all others?
What activates it>
trypsinogen
enterokinase
What molecules act as a safe guard in the pancreas to prevent from active trypsin degrading the pancreas?
pancreatic secretory trypsin inhibitor
Why does the pancreas not digest itself?
What is the co-localization theory for pancreatitis?

Lab findings for dog and cat w/ pancreatitis
Levels for the pancreatic lipase test?
Clinical meaning of a +/- test?
<200 no pancreatitis; >400 likely pancreatitis
+= maybe?
- = likely not pancreatitis
What condition beside pancreatitis can increase pancreatic lipase levels?
hyperadrenocorticism (steroids)
Rad findings w/ pancreatitis?
U/S results for pancreatitis
Tx for pancreatitis
fluids (K+ supp)
pain meds
anti-emetics
nutrition- traditional fast 3-5d or no vomit for 24hrs (GI mucosal barrier may be negatively affected- feeding earlier found to be better- E/G/J tubes )
reintroduce low fat diet then transition to normal diet if not recurrent
