Case 1 - Upper GI bleeding Flashcards
Common risk factors for GI bleeding
- Anticoagulants
- NSAID use
- Varicies/chronic liver disease
Important clinical examination findings to document for upper GI bleed
- BP
- HR
- Malaena?
- Haematemesis/coffee ground vomit?
- Signs of chronic liver disease - spider naevi, clubbing, gynaecomastia, palmar erythema
- Renal failure signs
- Heart failure signs
Investigations for upper GI bleed
- FBC - Hb, platelets
- U&Es - increased urea can be a sign for upper GI bleed
- Clotting
- Group and Save
- Crossmatch
- LFTs - CLD
- VBG - get Hb fast
- Endoscopy maybe?
Why do you get high urea in upper GI bleed?
- Blood is digested to protein
- PRotein transported to the liver
- Broken down into BUN in urea cycle (blood urea nitrogen)
What scoring system is used for upper GI bleeding?
- Glasgow Blatchford score - first assessment, assess if can be managed as outpatient or inpatient
- Rockall score after endoscopy - perecentage risk of re-bleeding and mortality (split into pre and post endoscopy)
What does ROCKALL score take into account?
- Age
- Features of shock
- Co-morbidities
- Aetiology of bleeding (cause)
- Stigmata of recent haemorrhge - blood in upper GI tract, spurting vessel, adherant clot
What does Glasgow Blatchford score take into account?
- Urea
- Hb
- Systolic BP
- Other - pulse, malaena, syncope, hepatic disease, cardiac failure
Immediate management for upper GI bleed patient - emergency
- A-E assessment
- Platelet transfusion if actively bleeding platelet count less than 50 x10^9
- FFP is fibrinogen less than 1g/litre or PT/aPTP more than 1.5x normal
- Prothrombin complex if on warfarin and actively bleeding
- Endoscopy after resucitation - must be within 24hrs
Management of non-varcieal bleeding
- PPI if non-variceal and stigmata of recent bleeding shown on endoscopy
- No PPI if just non-variceal bleeding
- If further bleeding - repeat endoscopy, interventional radiology or surgery
Management of variceal bleeding
Before endoscopy:
* Terlipressin
* Prophylactic abx
Then:
* Band ligation + injection of N-butyl-2-cyanoacrylate for patients with gastric varicies
* Sengstaken-Blakemore tube
* TIPs offered if bleeding not control via these measures (transjugular intrahepatic portosystemic shunt) (hepatic vein to portal vein connedction)
When can we not give Terlipressin?
If history of ischaemic heart disease
Monitoring for pt with upper GI bleed needed
- BP
- Monitor any vomit and stools passed
Long term management of oesophageal varices - prevent bleeding
- Propanolol
- Endoscopic variceal band ligation (2 weekly intervals until eradiacted)
- TIPs
Pathophysiology of oesophageal varices
- Cirrhosis = stiff, inexpansible liver
- Increased pressure in portal veins
- Increased pressure in portal venous sytem
- = portal venous system to systemic venous sytem shunt via anastomoses that are already present
- Dilated veins
Pathophysiology of peptic ulcer disease
- Defect in gastric/duodenal mucosa that extends to muscularis mucosae
- RF inc NSAIDs, H-pylori, physiological stress
