Benefits of a standardised feeding regimen during a clinical trial in preterm neonates.

The feeding regimen was standardised for a trial of erythromycin to reduce the time to reach full feeds (150 ml/kg/day) by 30% in neonates of < or = 32 weeks gestation. No significant improvement was noted in the primary outcome (median time: erythromycin 93.5 vs placebo 104 hours, p = 0.60). However, necrotising enterocolitis > or = stage II disappeared and the time to full feeds was reduced by over 50% in all neonates during the 18-month trial, and for more than two years after the trial, when the standardised feeding regimen was adopted as routine policy for feeding neonates of < or = 32 weeks (< 28 weeks: 13 vs 4.8 days, p < 0.05; > 28 weeks: 8 vs 3.9 days, p < 0.05). This was in contrast to an average of six cases of NEC per year with 45% mortality during the previous five years. The benefits of standardised feeding schedules--improved detection/treatment of signs/symptoms of feed intolerance--are emphasised.
