Gastrointestinal hemorrhage (GI bleeding) is defined as "bleeding in any segment of the gastrointestinal tract from esophagus to rectum."[1]
Diagnosis
Upper gastrointestinal tract bleeding
Esophagogastroduodenoscopy (EGD) can help determine the cause of the bleeding. Intravenous erythromycin prior to endoscopy can help clear the stomach of blood to improve the exam.[2]
Lower gastrointestinal tract bleeding
Prognosis
Upper gastrointestinal tract bleeding
For patients wtih nonvariceal upper gastrointestinal tract bleeding, the Blatchford score is a clinical prediction rule for predicting patients that will require blood transfusion, endoscopic or surgical management for bleeding control.[3]
The score is high risk if the patient has any of the following:
- Blood urea nitrogen ≥18.2 (mg/dL)
- Hemoglobin level
- for men <13 (g/dL)
- for women <12 (g/dL)
- Systolic blood pressure <109(mm Hg)
- Pulse rate ≥100 beats/min
- Melena
- Syncope
- Hepatic disease
- Heart failure
In a study in which 69.5% of the patients were had blood transfusion, endoscopic or surgical management, the accuracy fo the score is:
- sensitivity = 99.6%
- specificity = 25.0%
which yielded:
- positive predictive value = 75.2%
- negative predictive value = 96.4%
