The significance of gastric residuals in the early enteral feeding advancement of extremely low birth weight infants.

Objective: To evaluate whether the mean gastric residual volume (GRV) and green gastric residuals (GR) themselves are significant predictors of feeding intolerance in the early enteral feeding advancement in extremely low birth weight (ELBW; <1000 g) infants.

Design: Ninety-nine ELBW infants were fed following a standardized protocol (day 3--14). At 48 hours of age, milk feeding was started (12 mL/kg/d increments, 12 meals per day).
