GI Disease Flashcards
What are the concerns with megaesophagus?
- regurgitation and aspiration
- gastroesophageal reflux
What can result from reperfusion of compromised tissue?
- release of inflammatory mediators
- vasodilation, hypotension, decreased inotropy, or ventricular arrhythmias
What can happen with manipulation of the GI tract?
- vagal stimulation
- severe bradycardia
Which drugs should be used for pre-med in a hemoabdomen patient?
opioids and benzodiazepines IV
Which drug is used to control ventricular arrhythmias?
Lidocaine
Which drugs are used for induction in a hemoabdomen patient?
fentanyl + midazolam + small amount of propofol or ketamine
- can also use alfaxalone or etomidate
What is the common serum chem abnormality in patients with GI foreign bodies?
hypochloremic metabolic alkalosis
Which drugs should be avoided in a patient with non-septic GI foreign body?
acepromazine
dexmedetomidine
Which drugs can be used in a patient with non-septic GI foreign body?
opioids and benzodiazepines
Which drugs should be avoided in a patient with septic/sick GI foreign body?
acepromazine
dexmedetomidine
etomidate
Which conditions are common in a dog with gastric-dilatation volvulus?
- hypovolemic shock
- ventricular arrhythmias
- hypoventilation due to distended stomach compressing diaphram
Which drugs can be used for induction of a patient with GDV?
- opioid-benzodiazepine or alfaxalone
- low dose propofol or ketamine can be used
What drugs should be used in equine colic patients?
- alpha-2 agonist, NSAID, +/- butorphanol already on board
- xylazine-butorphanol premed
- ketamine-diazepam induction
- lidocaine CRI
- intermittent butorphanol every hour
What are common complications with equine colic patients?
- hypotension/poor perfusion
- hypoxemia
- hypercapnia
- often have poor recoveries
