| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group undergoing gastric ultrasound | Children between 0-18 years of age and ASA I-II patients will be included in the study. Stomach contents and volume will be determined with ultrasound and the postoperative effects of the values found will be examined. Gastric ultrasound will be performed before anesthesia induction, with children in the supine and lateral decubitus positions, using either a linear high-frequency or abdominal probe, depending on the age of the child, to obtain a sagittal section of the antrum in a plane that includes the left lobe of the liver and the aorta. |

| Measure | Description | Time Frame |
|---|---|---|
| Qualitative assessment of residual gastric fluid volume | 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. | preoperative evaluation in the operating room |
| Measure | Description | Time Frame |
|---|---|---|
| Gastric content volume | 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. | preoperative evaluation in the operating room |

| Antral cross-sectional area | 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. | preoperative evaluation in the operating room |
