Death below 2 g/dL of Hemoglobin Concentrations: As an Independent Predictor of Death

Abstract

Fifty three years old, healthy female patient had presented an acute severe anemia after intestinal bleeding within 2 days. She was hemodynamically stable even during extreme hemodilution with hemoglobin (Hb) below 3 g/dL. However, her condition deteriorated dramatically after Hb nearly 2 g/dL. The patient died solely of anemia at a hemoglobin concentration of 1.2 g/dL. We presumed the hemoglobin concentrations below 2 g/dL are maximally life-threatening; this is the terminal hemoglobin threshold that the hemoglobin concentration could be an independent predictor of death.
