Hypothesis: That a high hemoglobin threshold for transfusion in extremely low birth weight (ELBW) infants is associated with a lower rate of survival without severe morbidity (defined as one or more of retinopathy of prematurity, bronchopulmonary dysplasia, or periventricular leukomalacia/ventriculomegaly).

Primary Objective: To determine whether either a liberal or more restrictive threshold of hemoglobin level for red cell transfusion in ELBW infants is safer, by randomizing to either a high transfusion hemoglobin threshold or a low transfusion hemoglobin threshold.

Follow-up at a corrected age of 18 months represents a conventional age at which to first assess neurodevelopmental outcomes, and to predict long-term outcomes.

Further study details as provided by McMaster University:

Primary Outcome Measures:
  • Neonatal phase:
  • Survival to tertiary hospital discharge without severe morbidity (one or all of bronchopulmonary dysplasia, retinopathy of prematurity Grade 3-4, periventricular leukomalacia/ventriculomegaly present on ultra-sound scans at corrected age 34 weeks)
  • Follow-up phase:
  • Combined mortality or neurodevelopmental disability (non-ambulatory cerebral palsy, blindness, deafness, cognitive delay) at 18 months corrected age

Secondary Outcome Measures:
  • Neonatal phase:
  • growth in weight and head circumference
  • time to extubation
  • time on oxygen
  • length of hospital stay until discharge home
  • incidences of necrotizing enterocolitis
  • apnea requiring treatment
  • number of infections
  • use of post-natal steroids
  • intraventricular hemorrhage Grade 4 or with hydrocephalus
  • mean levels of hemoglobin
  • number of transfusions
  • number of donor exposures
  • Follow-up phase:
  • milder forms of cerebral palsy
  • milder neurologic disorder
  • personal and social functional capabilities
  • hydrocephalus requiring a shunt
  • seizure disorder
  • respiratory disease
  • iron nutritional status
  • physical growth including head size
