Flashcards in GDV Deck (15):
1

What are the clinical signs of GDV?

Agitation, restlessness, lethargy Progressive abdominal distention Unproductive vomiting/retching Collapse Signs of hypovolaemic shock Abdominal distension and tympany

2

Which breeds are over represented?

Great danes GSDs Irish setters Standard poodles

3

What are the extrinsic risk factors for the development of GDV?

Feeding a small number of large meals Speed eating n.b. it is thought to arise as a result of aerophagia

4

What is the key reason why GDV will develop?

Failure to eructate/lack of pyloric outflow (delayed gastric emptying)

5

What are the main effects of GDV?

  • Local:
    • gastric pressure and small vessel avulsion (also thrombi formation) -> necrosis -
    • pressure and avulsion of splenic vessels (also thrombi formation) -> necrosis -
    • pressure on diaphragm -> poor ventilation
  • Systemic
    • Pressure on caudal vena cava hepatic portal vein -> hypovolaemia
    • Ischaemic reperfusion injury (IRI)
    • Gastric perforation
    • Severe SIRS & DIC

6

What should be done straight away when a dog presents with GDV?

Treat the shock:

  • Fluid therapy
  • PCV, TS, electrolytes and venous blood gas

n.b. may need to give blood products or colloids if indicated by the PCV

7

When should analgesia be given to a GDV patient and when?

Straigh away - a pure opiod, this will also provide some sedation for later procedures

8

Other than fluid therapy and analgesia, what else can be done on presentation of GDV?

ECG if available

9

What are the steps that should be carried out after things have been done to stabilise the patient?

  • Gastric decompression
    • Oro-gastric tube
    • Percutaneous gastrocentecis
  • Can do radiography, although not essential
  •  

10

What should be remembered when aneasthatising a dog with circulatory compromise?

A reduced amount of induction agent is needed.

11

Are antibiotics indicated for GDV patients?

Yes they are perioperatively. Post-operatively they may be given if there is contamination at the time of surgery.

12

What are the aims of surgery on a GDV patient?

  1. Decompression and derotation of the stomach.
  2. Removal of necrotic tissue
  3. Gastropexy

 

13

What does a stomach covered in omentum indicate in an ex lap?

This indicates that the stomach has rotated.

14

What region of the stomach, if necrosed, would indicate euthanasia?

The cardia to pyloric region, if there is no chance of the dog having a functional stomach then euthanasia is indicated

15

What might form the post operative care for a GDV patient?

  • Fluids
  • Potassium supplementation
  • Analgesia
  • Treatment for gastric ulceration
  • Gastric motility drugs
  • Antibiotics
  • Nutrition
