Gastrointestinal hemorrhage in patients in a respiratory intensive care unit.
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 days of hospitalization; and (3) the development of thrombocytopenia. Factors not associated with an increased risk of gastrointestinal hemorrhage were the age and sex of the patient, the respiratory diagnosis of chronic obstructive pulmonary disease, and the use of therapy with either heparin or corticosteroids. Routine prophylactic administration of antacids was associated with a decreased incidence of hemorrhage. The mortality of bleeders was significantly greater than that of nonbleeders.
