In the patient who has active upper GI bleed, upper gastrointestinal tract bleed from an ulcer, what we would do is stabilize a person, protect their airway, give them IV fluids and blood if necessary. Okay. Get them stabilized and then we would perform an endoscopy or use that fiberoptic scope, pass it down to the area of the ulceration, and then we’d probably either inject the chemical to constrict the blood vessels to slow down bleeding. We may pass clips through the scope to actually clip the vessel, or we could use the device and actually coagulate or burn the visible vessel to stop the bleeding. If that didn’t work, then surgical intervention may be necessary. And/or sending the patient to Interventional radiology.
