upper gi bleed. the patient presented with hemodynamically significant coffee-ground emesis and melena. he was mildly tachycardic and mildly hypotensive (90's/50's) on presentation. the patient was admitted to the micu. emergent egd revealed erosive ulcerations in the esophagus and erosive gastritis. likely this is secondary to chronic nsaid use. the patient was placed on a ppi twice daily and all nsaid's were held. he was initially npo, though his diet was advanced without problem. the patient was maintained with an active t&s and 2 large bore peripheral iv's, though he had no more hemodynamically significant bleeding. the patient's hct stabilized around 26-29 and he was transferred to the medicine floor. of note, the patient was h. pylori serology antibody negative. the patient was given a prescription for repeat hct check to be completed 5 days after discharge. iron studies were pending at the time of discharge. . #
