Researchers at UNC–NC State developed an injectable microgel designed to reduce bleeding in infants undergoing surgery, reporting at least a 50% reduction in an animal model. The hemostatic “BK-TriGs” (B-knob-triggered microgels) are designed to match neonatal-specific clotting dynamics, a contrast to adult-derived transfusion practices. The team, led by Ashley Brown and colleagues, published the work in Science Advances, highlighting that neonatal hemostasis differs from adults and that transfusing adult blood products can increase safety risks including thrombosis. The microgel approach aims to reduce bleeding while potentially lowering the need for adult blood transfusions. For pediatric surgeons and translational developers, the key development is modality specificity—targeting the neonatal hemostasis mechanism rather than adapting adult protocols.
