Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Qualitative assessment of residual gastric fluid volume | preoperative evaluation in the operating room | Grade 0: Defined as no contents visible in the antrum, the stomach is empty and the volume of the contents approaches zero. Grade 1: Visible clear fluid with a fluid volume of \<1.5 mL/kg. Grade 2: Defined as visible clear fluid with a fluid volume of \>1.5 mL/kg in both the supine and lateral decubitus positions. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gastric content volume | preoperative evaluation in the operating room | It will be calculated using a mathematical model validated in children aged 11 months to 18 years. Volume(mL/kg) = \[-7.8 + 0.035 × antral area measured in lateral decubitus position (mm2) + 0.127 × age (months)\] / body weight (kg). The R² value for this model was 0.60. |
| Antral cross-sectional area | preoperative evaluation in the operating room | In both supine and lateral decubitus positions, between antral contractions, serosa to serosa, measuring the length diameter (D1) and the anteroposterior diameter (D2); Antral area = (π × D1 × D2) / 4 will be measured using the formula. |
