Causes of Upper GI Bleeding

There are many causes for upper GI hemorrhage. Causes are usually anatomically divided into their location in the upper gastrointestinal tract. Patients are usually stratified into having either variceal or non-variceal sources of upper GI hemorrhage, as the two have different treatment algorithms and prognosis.

The causes for upper GI hemorrhage include the following:

  • Duodenal causes:
    • Duodenal ulcer
    • Vascular malformations, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at the third or fourth portion of the duodenum where it is retroperitoneal and near the aorta.[1][2][3]
    • Hematobilia, or bleeding from the biliary tree
    • Hemosuccus pancreaticus, or bleeding from the pancreatic duct

Primary treatment option
Atropine
❑ Administer a first dose 0.5 mg IV bolus
❑ Repeat every 3-5 minutes
❑ Administer a maximum dose of 3 mg
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Secondary treatment options
If atropine ineffective:
❑ Administer dopamine infusion (2-10 mcg/kg/min)
OR
❑ Administer epinephrine infusion (2-10 mcg/min)
OR
❑ Proceed with transcutaneous pacing
 
 
 
 
 
 
 
 
 
 
 
 
 
 
❑ Consult a cardiologist
❑ Consider transvenous pacing
