The feeding intolerance prediction scoring system for very preterm and VLBW infants.

Predictors	Score
RI >0.785	2
GRV >25%	2
Intestinal peristaltic frequency ≤18 × /2 min	2
Hemorrhagic gastric fluid color	2
Abdominal distension	1
Interpretation Score ≥ 5: stop feeding Score 4: continued feeding without volume advancement and a re-evaluation in the next feeding schedule in 24 h Score ≤ 3: continue feeding
Notes: 1.US and clinical examinations are performed at the age of 5–7 days. 2.Clinical assessment (hemorrhagic gastric fluid color and abdominal distension) is observed within the last 24 h 3.Formula for gastric residual volume percentage: $\frac{\mathrm{Gastric}\mathrm{residual}\mathrm{volume}}{\mathrm{Previous}\mathrm{feeding}\mathrm{volume}}\times 100$
