Abstract
In areas with suboptimal resources, blood transfusion may not be feasible even when mandatory for severely anemic children with a life-threatening disease. We evaluated how much not having received a transfusion affected the survival in 171 children with an admission blood hemoglobin level of < 6 g/dL and bacterial meningitis in Luanda, Angola. Of these children, 75% (128 of 171) had received a blood transfusion during hospitalization, but 25% (43 of 171) had not. Within the first week, 33% of patients (40 of 121) with transfusion and 50% (25 of 50) without a transfusion died (P = 0.04). Early transfusion (days 1-2 of hospitalization) prolonged the time of survival from a median of 132 hours [interquartile range (IQR), 15-168] to 168 hours (IQR, 69-168; P = 0.004), and had odds of 0.49 (95% CI, 0.25-0.97; P = 0.040) for death compared with no transfusion. The effect of transfusion/no transfusion at any time during hospitalization on mortality within 30 days, and prolongation of the time of survival were similar to early transfusion but showed even clearer benefits. Our results emphasize the value of timely transfusion in facilities that care for severely anemic children with severe infections to maximize their chances of survival.
