Objective: To compare the effect of two-hourly (Q2H) vs. three-hourly (Q3H) feeding on time to achieve full enteral feeding, growth metrics and respiratory tolerance in very preterm infants with birth weight ≤ 1250 g.
Study Design: Retrospective study review of 18 months before and after a change in our feeding guideline from Q3H to Q2H feedings.
Results: 113 infants were included, 59 in Q3H and 54 in Q2H groups. Q2H infants required 10% more days to achieve full enteral feeding, however it was not statistically significant (P = 0.054). Q2H feeding was associated with 16% more central catheter days (P = 0.02) and 17% more parenteral nutrition days (P = 0.019). There were no differences in respiratory outcomes or growth metrics between the groups.
Conclusion: Very preterm infants fed Q3H had less central catheter and parenteral nutrition days when compared to those fed Q2H, without significant differences in growth or respiratory outcomes.
