ABC, protect the airway, IV access with large bore cannulas. Fluids.

2

What is the 100 rule for poor prognostic group in a GI bleed?
What others are also included in this group?

Systolic under 100
Pulse over 100
HB under 100g/L

Aged over 60
Comorbid disease
Postural hypotension.

3

What is the blatchford score?

Is used to assess GI bleed patients status. Uses BP, Hb, urea etc.

4

What is stigmata of recent haemorrhage?

Active bleeding or oozing or an overlying clot or visible vessel.

5

What are the endoscopic treatments of peptic ulcers?

Injection, heater probe coagulation, clips and haemospray.
Can be given 1:10000 adrenaline to cessation bleeding during the procedure.

6

How does haemospray work?

When comes into contact with blood, the powder absorbs water, which forms a barrier over the bleeding site.

7

What are risk factors for bleeding oesophageal varices?

Portal pressure of over 12mmHg
Varices extending over 25% into the lumen.
Presence of red signs
The degree of liver failure.

8

When should we suspect varices in a bleeder?

Known history of varices or cirrhosis.
History: chronic alcohol excess, chronic viral hepatitis infection, metabolic or autoimmune liver disease.
On examination: stigmata of chronic liver diseases such as spider naevi, ascites, jaundice, palmar erythema leukonychia and encephalopathy.

9

How is haemostasis achieved in bleeding varices?

Terlipressin (vasopressin analogue)
Endoscopic variceal ligation.
Sclerotherapy
Sengstaken-blakemore tube
TIPS procedure.

10

What does terlipressin do?

Predominantly splanchnic vasoconstriction and has a beneficial effect on renal perfusion.
Superior to vasopressin and somatostatin.

11

What veins cause oesophageal varices?

The periesophageal venous plexus.

12

What is a TIPS procedure?
What is it used for?

Burrow through the liver to place a shunt between the portal vein and one of the hepatic veins to try and reduce portal pressure.
Known cirrhosis liver with uncontrollable bleeding oesophageal varices.
