A

Haematemesis

2
Q

What is it called when there is blood in the faeces?

A

Melaena

3
Q

What is the most common cause of GI bleeding?

A

Duodenal ulcer

(followed by gastric erosions, gastric ulcers, varices….)

4
Q

Which factors can indicate the severity of haemorrhage?

A
  • sBP < 100mmHg
  • Pulse > 100bpm
  • Hb < 100g/l
  • Age > 60
  • Comorbidities
  • Postural drop in BP
5
Q

Why is it often young people that are more dangerous during haemorrhage?

A

They have much more compliant ANS so can compensate and appear well up until the last possible second when they eventually crash

Old people will show a gradual decline so give many early warning signs

6
Q

Why must endoscopy be done as soon as possible after bleeding?

A

Cause must be identified

Therapeutic management

Risk of re-bleeding can be assessed

7
Q

Recent haemorrhage has which three key signs?

A
  1. Active bleeding or oozing
  2. Overlying clot
  3. Visible vessel
8
Q

What are the potential treatment options for GI bleeding?

A
  • Endoscopic
  • Acid suppression - PPI
  • Interventional radiology
  • Surgery
  • H. pylori eradication
9
Q

What is the PPI of choice?

A

Omeprazole

10
Q

Acute variceal bleeding is as a result of what?

A

Portal hypertension

11
Q

What is the TIPSS procedure?

A

A resue therapy

A wire is inserted through the hepatic vein which has pressure sensors to detet the portal vein

A balloon passes via the vein allowing a stent to be insterted

Bleeding in the varices stops because there is no longer a driver for the bleeding - pressure is normalised
