Q1 Exam 2 Flashcards
five layers of gut from inner to outer
mucosa, submucosa, circular muscle, longitudinal muscle, serosa
three oxyntic gland cells and what they produce in the stomach
parietal cells: HCl, intrinsic factor
chief cells: pepsinogen
ECL cells: histamine
two pyloric gland cells and what they produce
D cells: somatostatin if pH is too low
G cells: gastrin
PPIs
omeprazole more broad spectrum acid reducer than famotidine, but not as fast, might increase effects of other drugs
sucralfate
needs acidic environment to work properly (give on empty stomach before PPI?, can cause constipation
exocrine pancreatic secretions
bicarb, intrinsic factor allows for B12 absorption, enzymes like trypsin (master key)
cisapride
prokinetic that can be given at home, but need to get compounded
apomorphine
dopamine receptor agonist (only works in dogs CRTZ) 75% successful at removing foreign object
how does the feline esophagus differ
1/3 smooth muscle
treatment for congenital megacolon
sildenafil, supportive care
megacolon secondary to in 25% cats
thymoma
lower esophageal achalasia like syndrome
bird beak sign, failure of LES to relax, treat with mechanical dilation and botulism toxin, then maybe surgery
spirocerca lupi
esophageal worm, special float, granulomas turn into cancer (and not sccs)
GERD treatment
prokinetics, acid suppression, sucralfate, maybe LF diet
common labwork findings for foreign body
hypochloremic metabolic acidosis
L lateral what should we see in stomach
gas in pylorus
how to stabilize GDV patients
correct hypovolemia, correct arrhythmias
manage pain
decompress stomach
