Figure 3 Serial hemoglobin (Hb) concentrations during hospitalizationHemoglobin levels declined sharply from 11.5 g/dL at 4 h post-admission to 6.3 g/dL at 24 h, consistent with ongoing intra-abdominal hemorrhage. Subsequent transfusion of packed red blood cells and supportive care facilitated hematologic recovery, with levels rising to 11.6 g/dL by day 4 and stabilizing thereafter. Final hemoglobin measured 13.4 g/dL on day 18, indicating restored hemostasis and resolution of hemoperitoneum.
