Early Predictors of Severity in Acute Lower Intestinal Tract Bleeding

摘要: Background Identification of high-risk patients with lower intestinal tract bleeding (LIB) is challenging, and prognostic factors have not been clearly defined. The aim this study was to determine risk for severe acute LIB. Methods A total 252 consecutive admitted LIB were identified. Data collected on 24 clinical available in the first 4 hours evaluation. outcome bleeding, which defined as continued within hospitalization (transfusion ≥2 units blood and/or hematocrit decrease ≥20%) recurrent after stability (additional transfusions, further ≥20%, or readmission 1 week discharge). Results Severe occurred 123 (49%). Independent correlates follows: heart rate, ≥100/min (odds ratio [OR], 3.67; 95% confidence interval [CI], 1.78-7.57); systolic pressure, ≤115 mm Hg (OR, 3.45; CI, 1.54-7.72); syncope 2.82; 1.06-7.46); nontender abdominal examination 2.43; 1.22-4.85); per rectum during evaluation 2.32; 1.28-4.20); aspirin use 2.07; 1.12-3.82); more than 2 active comorbid conditions 1.93; 1.08-3.44). Conclusion Clinical data initial can be used identify at LIB, who may benefit most from urgent intervention.
