The remainder will have weighed more than 2,000 g at birth and will have required oxygen therapy for at least 18 of their first 36 hours.

These infants are being assigned to one of five groups on the basis of birth weight. Within a group, they are assigned randomly to treatment with vitamin E (dl-a-tocopherol) or a placebo. The vitamin or placebo is administered by infusion to those infants (about seven of ten) who already are receiving intravenous
