ΔGV and actual drinking volume in the two groups
| ΔGV (ml, mean ± SD) | actual drinking volume(ml) | P-value | |
|---|---|---|---|
| Group C (n = 50) | 298.2 ± 11.0 | 300 | 0.260 |
| Group E (n = 50) | 300.2 ± 10.6 | 300 | 0.887 |
| Total (n = 100) | 299.2 ± 10.9 | 300 | 0.470 |
GV0 Gastric volume before oral liquid, GV1 Gastric volume immediately after oral liquid, GV2 Gastric volume before induction, ΔGV = GV1-GV0, SD Standard deviation
P-value indicates the statistical difference between the ΔGV and actual drinking volume
