Significant gastrointestinal hemorrhage occurred in 20% (20) of the patients in a respiratory intensive care unit. Risk factors significantly associated with the development of gastrointestinal hemorrhage included (1) the principal respiratory diagnosis of adult respiratory distress syndrome; (2) increasing numbers of days on a ventilator, days in the respiratory intensive care unit, and total ...

BACKGROUND AND PURPOSE Patients with ischemic or hemorrhagic stroke are at risk for systemic complications. The reasons why gastrointestinal bleeding occurs after stroke are unknown and have intuitively been attributed to stress ulcers. No study to date has addressed causes of gastrointestinal hemorrhage in stroke. METHODS Between 1976 and 1994, 17 patients identified from the Mayo Clinic med...

massive upper gastrointestinal bleeding is a known complication of advanced sepsis in trauma patients and carries a grave prognosis. however, to our knowledge, an important cause of massive gastrointestinal bleeding, arterio-visceral fistula, has not been discussed in the literature. the most common cause of this unique clinical entity is penetrating high velocity abdominal injuries, although b...

IMPORTANCE Optimizing the nature and sequence of diagnostic imaging when managing lower gastrointestinal hemorrhage may reduce subsequent morbidity and mortality. OBJECTIVES To determine if preceding visceral arteriography with computed tomographic angiography (CTA) in acute lower gastrointestinal hemorrhage increases hemorrhage identification and localization and to determine if CTA was supe...

INTRODUCTION Warfarin is a widely used and easily reversible anticoagulant. Although bleeding is more likely in warfarin users, it may also be more readily treated. This retrospective observational case-control study compares the outcome of acute nonvariceal upper gastrointestinal hemorrhage in warfarin users with a supratherapeutic international normalized ratio (INR) and outcome in non - warf...
