| | ACEP: Nasogastric Lavage Fails to Predict Need for Transfusion in Cases of Upper Gastrointestinal Bleeding (Site not responding. Last check: 2007-10-15) |
 | | SEATTLE, WA -- October 11, 2002 -- Positive nasogastric tube lavage for acute upper gastrointestinal bleed is not predictive of the need for packed red blood cell (RBC) transfusion, according to results of a study presented at the 2002 Scientific Assembly of the American College of Emergency Physicians (ACEP). |
 | | The gastric lavage results were recorded as clear, bilious, blood-tinged, coffee grounds, or gross blood. |
 | | Thirteen of the 21 patients had a positive nasogastric lavage, demonstrating a sensitivity of just 62 percent and a specificity of 57 percent to predict the need for transfusion. |
