Clinical Scenario
A 84 yo woman arrives in ED in midnight coming from a nursing because of a reported episode of coffee ground vomiting.
Respiratory rate, heart rate and blood pressure are normal, abdomen is not distended, hemoglobin level is 10 g/dl. On rectal examination you find normal stool.
She takes warfarin.
Can a nasogasric lavage (NGL) contribute to rule out an upper gastrointestinal bleeding (UGB)?
