At least 5 of every 1000 live-born babies are very premature and weigh only 500 to 1250 grams at birth. Approximately 30-40% of these high-risk infants either die or survive with lasting disabilities. The aim of this research is to reduce this heavy burden of illness. A multi-center randomized controlled trial has been designed in which 2000 very low birth weight infants will be enrolled. Our goal is to determine whether the avoidance of methylxanthine drugs will improve survival without disability to 18 months, corrected for prematurity.
Methylxanthine drugs such as caffeine are used to prevent or treat periodic breathing and breath-holding spells in premature infants. However, there is a striking lack of evidence for the long-term efficacy and safety of this therapy. Methylxanthines block a naturally occurring substance, called adenosine, which protects the brain during episodes of oxygen deficiency. Such episodes are common in infants who are treated with methylxanthines. It is possible that methylxanthines may worsen the damage caused by lack of oxygen. Therefore, this trial will clarify whether methylxanthines cause more good than harm in very low birth weight infants.

- Drug: Caffeine citrate injection
Loading dose: 20 mg/kg administered over at least 30 minutes via IV infusion or over at least 10 minutes via slow IV injection.
Daily maintenance dose (to commence at least 24 hours after loading dose): 5 mg/kg, administered over at least 10 minutes via IV infusion, or over at least 5 minutes via slow IV injection. Maintenance dose to be adjusted for body weight every 7 days. If indicated, maintenance dose may be increased to a maximum of 10 mg/kg. May be given orally once full enteral feeds are established.
Duration of treatment: discontinue after infant has tolerated at least 5 consecutive days without positive pressure support AND when the infant is judged by the attending clinician to be no longer a candidate for methylxanthine therapy.
