Recent advances in neonatal hematology, largely made by the authors of these chapters, are likely to generate wide spread and long-term improvements in outcomes, as well as reductions in costs of care. Publication of these advances in a single volume will facilitate dissemination of these techniques and practices. The advances include neuroprotection from erythropoietic stimulators, improved guidelines for platelet transfusions, evidence-based guidelines for FFP administration, improved diagnostic methods for genetic causes of severe neonatal jaundice, more accurate definitions of hematological perturbations in necrotizing enterocolitis and sepsis, and reduction in transfusions and in IVH rates by cord milking/delayed clamping.
