PRIMARY OBJECTIVE of study is to determine whether cerebral outcome is improved if infants born between 24 0/7 and 31 6/7 gestational weeks at birth receive erythropoietin in high dose in the first three days after birth. SECONDARY OBJECTIVES To determine whether early administration of EPO alters the incidence of complications typically associated with preterm birth, i.e. mortality, septicaemia, necrotising enterocolitis, bronchopulmonary dysplasia (oxygen dependency at 36 weeks postmenstrual age), retinopathy, intracranial haemorrhage, white matter disease (periventricular leucomalacia), growth failure, cerebral palsy and handicap at 5 years.
