title: Minimizing blood loss and the need for transfusions in very premature infants.
abstract: Reducing blood loss and the need for blood transfusions in extremely preterm infants is part of effective care. Delayed cord clamping is well supported by the evidence and is recommended for infants who do not immediately require resuscitation. Cord milking may be an alternative to delayed cord clamping; however, more research is needed to support its use. In view of concerns regarding the increased risk for cognitive delay, clinicians should avoid using hemoglobin transfusion thresholds lower than those tested in clinical trials. Higher transfusion volumes (15 mL/kg to 20 mL/kg) may decrease exposure to multiple donors. Erythropoietin is not recommended for routine use due to concerns about retinopathy of prematurity. Elemental iron supplementation (2 mg/kg/day to 3 mg/kg/day once full oral feeds are achieved) is recommended to prevent later iron deficiency anemia. Noninvasive monitoring (eg, for carbon dioxide, bilirubin) and point-of-care testing reduce the need for blood sampling. Clinicians should strive to order the minimal amount of blood sampling required for safe patient care, and cluster samplings to avoid unnecessary skin breaks.
