GI Bleeding Flashcards
What are the clinical features of an upper GI Bleed?
- Hematemesis,
- Malaena,
- Coffee ground vomit
- Tachycardia
- Hypotension
What are some causes of upper GI Bleeds?
- Oesophageal/gastric varices,
- Peptic ulcer disease,
- Gastritis/oesophagitis/duodenitis
- Malignancy,
- Angiodysplasia,
- Mallory Weiss tear
Explain the management of upper GI bleeds
- ABATED - A-E assessment, Bloods, Access, Transfuse, Endoscopy and Drugs (stop anticoagulants and NSAIDs)
- Resuscitation with fluids, or blood transfusion if Hb <7.
- In suspected variceal bleeding terlipressin and antibiotics.
- Once stable, an upper GI endoscopy is performed where they can attempt to stop the bleeds with bands/clipping/haemostatin spray/adrenaline/heater probe
What are some different scoring systems for upper GI Bleeding
- Rockall score
- Glasgow Blatchford score
What bloods should be requested in an upper GI Bleed?
Haemoglobin,
Urea
Coagulation
LFTs,
Crossmatch
When should you transfuse a patient with an upper GI bleed?
- Blood when Hb is under 7
- Give blood, platelets and FFP in massive haemorrhage,
- Platelets if platelet count is < 50
- Prothrombin complex concentrate and Vit K in patients who take warfarin and are actively bleeding
What is the initial management of an upper GI bleed if oesophageal varices are suspected?
Terlipressin and broad spectrum antibiotics
What factors are included in the Glasgow’s Blatchford score?
Blood urea,
Haemoglobin,
Systolic BP,
Pulse,
Presence of melaena,
Presence of syncope,
Heart failure,
Hepatic disease
If a GI bleed hasn’t been successfully treated endoscopically then what can be performed?
Radiological emobolisation of bleeding vessel or a TIPS procedure if varices are suspected
What is the prophylaxis and prevention for re bleeding varicies?
Beta blockers (carvediol) or band ligation
What are some causes of lower GI bleeding?
- Vascular eg, ischaemic colitis, angiodysplasia.
- Inflammatory causes eg, IBD.
- Infective colitis,
- Neoplastic causes eg, colon cancer or anal cancer,
- Haemorrhoids or anal fissures,
- Diverticular disease, Meckel’s diverticulum
- Endometriosis
What are the diagnostic tests for a lower GI bleed?
- Bloods - assess Hb
- Colonoscopy,
- CT angiogram
what is the management of a lower GI bleed?
- Stabalise patient (same transfusion parameters as upper GI bleeds)
- If unstable then do CT angiogram, if stable then colonoscopy
- Surgery (laparotomy is source is unclear) or selective mesenteric embolisation
When should you admit a patient with a lower GI bleed?
- If over 60yo
- Haemodynamically unstable or profuse PR bleeding
- On aspirin or NSAIDs
- Significant co-morbidity
What are the indications for surgery in a patient with a lower GI bleed?
- Over 60yo
- Bleeding continues despire endoscopic intervention
- Recurrent bleeding
- Known CV disease
