Haemorrhage and blood products Flashcards
symptoms of upper GI bleeding
haematemessi
altered bowel habit
abdominal pain
pre-syncope/syncope
clinical signs of upper GI bleeding
Tachycardia
Hypotension
Abdominal tenderness
Malaena: black, tarry stools caused by the presence of digested blood.
Haematochezia: the passage of fresh red blood per rectum, which can occur in the context of profuse upper gastrointestinal haemorrhage due to rapid transit of blood through the gastrointestinal tract.
Check for signs of liver disease
investigations for upper GI bleeding
Endoscopy, after calculating blatchford score, 0 can be managed in the community
Rockall score: risk of ongoing bleeding and death
PPI
Terlipressin
Cipofloxacin
major haemorrhage definition
Loss of more than one blood volume within 24 hours (around 70 mL/kg, >5 litres in a 70 kg adult)
50% of total blood volume lost in less than 3 hours
Bleeding in excess of 150 mL/minute.
red cell transfusion criteria
Red cell transfusion is usually necessary if 30–40% blood volume is lost, and rapid loss of >40% is immediately life threatening
complications of massive haemorrhage
hypothermia
hypocalcaemia
hyperkalaemia
delayed type transfusion reactions
transfusion related lung injury
coagulopathy
causes of upper GI bleeds
Oesophageal/gastric varices
Peptic ulcer disease (H. pylori, NSAID use, smoking)
Malignancy
Aorto-enteric fistula (previous abdominal aortic aneurysm or an aortic graft)
Angiodysplasia
Mallory Weiss tear
management of upper GI bleed
IV fluid resus and blood transfusion
NBM and supplemental oxygen
IV PPI
IV terlipressin and ax in variceal bleeding
upper GI endoscopy
rockall score
risk assessment tool that predicts mortality in these patients
It can be calculated pre-endoscopy (maximum score 7) or post endoscopy (maximum score 11).
Patients who score >0 are recommended to have an inpatient OGD whereas those scoring 0 can have an urgent outpatient OGD.
glasgow-blatchford score
The Glasgow-Blatchford score is preferred by NICE pre-endoscopy for deciding upon timing of the procedure.
Again those scoring<0 may be suitable for outpatient OGD.
