Flashcards in Vomiting or regurgitation? Deck (11):
1

Regurgitation

passive
no prodromal nausea
undigested food / froth
soon after eating
may be apinful
coughing
nasal discharge
dysphagia
anorexia uncommon

2

Investigating regurgitation causes?

unsedated chest rads
contrast rads
endoscopy

3

Regurgitation DDX?

Anatomic - vascular ring anomaly, cricopharyngeal disease, hiatal hernia, diverticulum

obstruction - stricture, luminal FB, extraluminal mass

Oesophagitis - trauma, reflex, irritation

Motility disorders - megoesophagus, neuropathy, myopaths

4

Most common causes of regurgitation?

Foreign body - lodge where physiological narrowing, remove/push to stomach

oesophagitis - chemical injury, medication (doxy in cats) , gastro - oesophageal reflux (anaesthesia, vom, feeding tube), use sucralfate and inhibit gastric acid

megaoesophagus - idiopathic, myasthenia gravis, thymoma, hypoadrenocorticism

5

Vomiting

abdominal effort
prodromal nausea
digested food
no swallowing pain
forceful expulsion
symptom - not disease

6

What can the vomiting centre in the brainstem be influenced by?

cortex

vagal and symp afferents from abdomen/stomach

chemoreceptor trigger zone in brainstem which detects blood borne substances

7

primary causes of vomiting

dietary
infection - parasites, parvo
inflammatory disease - IBD, ulcers
Neoplasia
Obstruction
motility disorders

mainly acute except neoplasia and infl disease

8

Secondary causes of vomiting

uaemia
addisons disease = hypoadrenocorticism
hepatic disease
pancreatitis (dog)
toxin ingestion
drugs
Acute renal disease

all chronic except toxin ingestion

9

Types of drugs to treat vomiting?

proton - pump inhibitors (stop HCl in stomach)

Anti-collinergics (stop vagus input)

Anti histamines (block parietal cells)

10

What is the guide used for how dilated the int is?

1.6 x the height of L5 = localised dilation = 90% sure of obstruction

11

Different types of contrast radiography (5)

pneumogastrogram - identify stomach, FB

food and barium gastogram - assess gastric emptying

Double contrast gastrogram - identify mucosal lesions

Upper GI contrast study - identify stomach, int, assess GI motility, identify obstruction

Barium enema - identify colon, intussesception, mural lesions
