Upper GI haemorrhage Flashcards
what are some of the causes of GI bleeds?
working top to bottom:
bleeding gastric ulcer, mallory-weiss tears, oesophageal varices, gastric erosions, duodenal ulcer, malignant small bowel tumours, angiodysplasia, polyps or carcinoma of the colon, ischaemic colitis, acute/fulminant UC, diverticular disease, rectal carcinoma, rectal polyps, haemorrhoids
what are the relevant points in the clinical Hx?
- Hx of cirrhosis and variceal bleeds
- aspirin / other NSAID use
- alcohol consumptions
- previous gastric ulcers
- previous gastric surgery
what constitutes a high risk patient?
what steps are taken in their care?
- 60+
- drop in systolic BP below 100
- presence of severe intercurrent disease e.g suspected liver disease
- Hb below 10g
steps:
admit into high dependency unit –> fluid resuscitation —>inform consultant –> observe for changes indicating rebleeding e.g increaser HR, drop in bp etc –> only sips of water until endoscopy –> endoscopy ithin 12 hrs
attempt to treat bleed endoscopically - if not successful then surgical intervention is required. if nothing is found on endoscopy then observe.
who is a low risk patient?
how are they managed?
> 60
previously fit
no indication of hypovolemia
Hb above 10g
steps:
admit onto ward –> allow fluids for first 24hrs then food –> observe for signs of re-bleeding –> arrange for an endoscopy on next elective list.
what investigations are performed in suspected GI haemorrhage?
what are the relevant findings?
labs:
bloods: FBC, LFTs, U&E, group and save + crossmatching
ECG and CXR may be considered in elderly with cardioresp disease
Endoscopy when possible:
look to identify the source of bleeding and potentially manage the patient
what endoscopic features can place low-risk patients in the high risk category?
active spurting of an artery in an ulcer bed - often need surgery
gastro-oesophageal varices - high mortality of 30%
visible elevated vessel/ protruding adherent clot (Dieulofoy lesion) - high risk of re-bleeding
when is surgery required?
- high risk + 1 rebleed
- 2 rebleeds
- unable to resuscitate / risk of exsanguinating haemorrhage –> laprotomy
