Flashcards in Management of Acute Upper GI Haemorrhage Deck (35)
What is haematemesis?
Blood in the vomit - upper GI bleeding
What is melaena
Blood in the stool - A sign of Upper GI bleeding
What is GI bleeding?
A serious medical emergency until proven otherwise
What are the majority of GI bleeds
Self limiting with no in-hospital rebleed
What is the mortality rate for patients with continued or recurrent bleeding?
What can cause upper GI bleeding
Mallory -Weiss tear (repeated vomiting and then the appearance of blood)
How can you control the blood pressure of a patient?
IV access to give fluids
What venflon should be used with GI bleeding?
What is the 100 rule?
systolic BP 100bpm
Postural drop in blood pressure
How many litres of circulating volume do you have?
How much can you afford to lose at a young age?
How much volume can you afford to lose at an older age?
What do you do if there is a high suspicion of GI bleed and what does this tell you?
to identify the cause
to manage the cause
assess the risk of rebleed
What scoring system is used for to measure the risk of a upper GI rebleed ?
What is it scored on?
Rockall RIsk Scoring system
Presence or absence of co-morbidity
What does the Blatchford Scoring system determine?
Why is this advantageous of the Rockall RIsk Scoring System
The high risk of GI bleeding patients
It does not require an endoscopy
What do we do for patients that score 0-1 on the Blatchford Scoring system?
Require an outpatient endoscopy
What are the 3 high risk stigmatas of recent haemorrhage
Active bleeding/ oozing
How can you achieve haemostasis
Get a balance of thrombosis and thrombolysis
What are the endoscopic treatments of peptic ulcers?
Injection (best is 1/10000 adrenaline - gives a tamponade effect and a pharmacological effect of vasoconstriction)
Heater probe coagulation
Clips - apply to achieve haemostasis
Haemospray - new device used as rescue therapy when the rest has not worked
What is the combination therapy?
Injection and heater probe coagulation
What is acute variceal bleeding
Varices are dilated submucosal veins, most commonly detected in the distal esophagus or proximal stomach
What causes variceal bleeding?
Complications such as sepsis and liver failure
What does intervention do in acute variceal bleeding?
Reduced bleeding related mortality
What happens as the resistance in the portal vein increases
The pressure increases and so the flow changes to try and find an alternative route back into the systemic system
When do you suspect varices in a bleeder?
Known history of cirrhosis with varices
History of chronic alcohol excess
Chronic viral hepatitis infection
metabolic or autoimmnue liver disease - intra-abdominal spesis/ surgery
What causes leukonychia?
Chronically low protein levels
What can portal hypertension cause
What are the aims of management of variceal bleeding?
Prevent complication of bleeding
Prevent deteriorating liver failrure
How do we achieve coagulopathy
Plasma donor and give Vitamin K
