1
Q

How does upper GI bleeding present?

A

Haematemesis
Coffee ground vomiting
Melaena
- black, runny stools

2
Q

What constitutes the upper GI?

A

Mouth
Oesphagus
Stomach
Duodenum

3
Q

List some of the causes of upper GI bleeding.

A
Peptic ulcer
Oesophagitis 
Gastritis
Duodenitis
Varices
Malignancy
Mallory- Weiss tear
- a tear in the mucous membrane where the gastro-oesophageal membrane
Other
4
Q

Name some causes of peptic ulceration.

A

Hypergastinaemia
H.Pylori
NSAIDs

5
Q

How is upper GI bleeding managed?

A

Resuscitate if required
- venflons and fluid
Risk assessment and timing of endoscopy
Drug therapy and transfusion

6
Q

How and when does a patient with upper GI bleeding need resuscitation?

A

If the BP is low and the heart rate is high
IV access gained for fluids and bloods
Check Hb and urea
Lie them flat and given them oxygen

7
Q

What are the risk assessment categories and related timings of endoscopy?

A
High risk
- emergency endoscopy 
Moderate risk 
- admit and next day endoscopy (most patients)
Low risk
- out patient management
8
Q

What is the Rockall Score?

A

Predicts the mortality for upper GI bleeding

9
Q

What components are assessed when predicting mortality with the Rockall score?

A
Age
Shock
- pulse
- systolic bp
Co-morbidities
10
Q

What admission risk markers are assessed with the Glasgow Blatchford Score (GBS)?

A
Blood urea 
Haemoglobin 
Systolic blood pressure 
Pulse
Presentation with melaena 
Presentation with syncope 
Hepatic disease
Cardiac failure
11
Q

When should the prognostic score be used?

A

Glasgow Blatchford Score used for initial assessment

Full Rockall score after endoscopy

12
Q

What are the stigmanta of bleeding?

A
High risk of rebleeding 
- active bloodclot 
- NBVV
Moderate risk of rebleeding 
- clot formation 
Low risk of rebleeding 
- dot
- clean base
13
Q

What endoscopic therapy can be used for treatment of upper GI bleeding?

A

Adrenaline injection to constrict the blood flow
Heater probe
Endoscopic clips to clip the open vessels shut
Thrombin injection to promote clotting
Laser (ablation - burn the open wounds shut)

14
Q

List the categories of treatment available for upper GI bleeding.

A
Endoscopic therapy 
Radiological embolisation (endovascular)
Emergency surgery (rarely needed)
Drug theapy
Blood transfusion
15
Q

Which drugs are useful in treatment of upper GI bleeding?

A

IV PPIs

- reduces rebleeding and mortality post-endoscopy

16
Q

What do you do if the patient is on antiplatelets or anticoagulants?

A

Aspirin
- continue low dose after bleeding once haemostasis is achieved (add PPI)
Stop NSAIDs
NOAC/warfarin
- discuss risk/benefit with CV team once haemostasis is achieved

17
Q

When are blood products used in upper GI bleeding?

A

Restrictive transfusion if Hb <7-8g/dL
Platelet transfusion is active bleeding and platelet count is <50x109/L
Fresh frozen plasma if INR >1.5
PT complex concentrate is on warfarin and they are actively bleeding

18
Q

What is the mortality rate of a ruptured variceal bleed?

A

30-40%

19
Q

How are unruptured variceals managed?

A

Endoscopic banding
or
Beta-blocker drugs (to reduce the portal pressure)
TIPS

20
Q

How is acute variceal bleeding managed?

A
Resuscitation
- restore circulating volume
- transfusion if Hb<7-8g/dL
- consider airway protection
Endoscopy for diagnosis
Therapy 
- antibiotics in the cirrhotic subset 
- vasopressors (terlipressin)
- endoscopic banding treatment
21
Q

What should you do in uncontrolled variceal bleeding?

A

Sengstaken tube
- tube inflated in the oesophagus to hold pressure on the bleeds
- balloon tamponade
TIPS
- transjugular intrahepatic portosystemic shunt
Surgical shunt/transection is TIPS fails

22
Q

In general, what is the optimal management of an upper GI bleed?

A

Resuscitate
Risk assess
Time endoscopy
Drug therapy and transfusion
