Correlations between GAA and TGV(w) or GFV(w) in children are best in the RDC position, but not sufficient to predict GFV(w) with a given GAA. Interpretation of isolated GAA values may be misleading.

In healthy volunteer children, residual GCV(w) 1 h after intake of 3 ml kg(-1) syrup is significantly smaller than that after 7 ml kg(-1) and within the range of baseline.

Residual gastric contents volumes at a hypothetical anaesthesia start were similar for 4 and 6 h food fasting in healthy volunteer school-age children.

Hunger and thirst scores vary considerably inter- and intra-individually and cannot predict gastric volume, nor do they correlate with fasting times in school age children.
