Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Distribution of Perlas Gastric Ultrasound Grades Between LVEF Groups | Preoperatively, immediately before induction of general anesthesia | The primary outcome is the comparison of Perlas gastric ultrasound grade distributions between patients with LVEF \<40% and LVEF ≥40%. Gastric contents will be assessed before anesthesia induction using the Perlas grading system: Grade 0, empty antrum in both supine and right lateral decubitus positions; Grade 1, clear fluid visible only in the right lateral decubitus position; and Grade 2, clear fluid visible in both positions. The number and percentage of patients in each grade will be compared between groups. |
| Secondary | Association Between LVEF and Estimated Gastric Volume (mL/kg) | Preoperatively, immediately before induction of general anesthesia | The association between left ventricular ejection fraction (LVEF) and estimated gastric volume (mL/kg) will be evaluated in patients with clear gastric fluid. Gastric volume will be calculated using the Perlas formula: 27.0 + (14.6 × antral cross-sectional area in cm²) - (1.28 × age in years). The estimated volume will be divided by body weight to obtain mL/kg. The formula will not be applied to patients with solid or thick particulate gastric contents. |
| Secondary | Gastric Antral Cross-Sectional Area (CSA) | Preoperatively, immediately before induction of general anesthesia | Gastric antral cross-sectional area (CSA) will be measured using preoperative ultrasonography in the right lateral decubitus position. CSA will be calculated from the anteroposterior and craniocaudal diameters using the formula: CSA = (AP diameter × CC diameter × π) / 4. CSA values, expressed in cm², will be compared between patients with LVEF \<40% and those with LVEF ≥40%. |
| Secondary | Presence of Solid Gastric Contents | Preoperatively, immediately before induction of general anesthesia | The presence of solid or thick particulate gastric contents will be assessed using preoperative gastric ultrasonography in the supine and right lateral decubitus positions. Findings will be recorded as present or absent. The number and percentage of patients with solid or thick particulate gastric contents will be compared between the LVEF \<40% and LVEF ≥40% groups. |
| Secondary | Prevalence of High-Risk Gastric Contents | Preoperatively, immediately before induction of general anesthesia | A high-risk stomach will be defined as an estimated gastric volume \>1.5 mL/kg or the presence of solid or thick particulate gastric contents on preoperative ultrasonography. Gastric volume will be estimated only in patients with clear fluid contents. The number and percentage of patients meeting the high-risk stomach criteria will be compared between the LVEF \<40% and LVEF ≥40% groups. |
