Registered outcomes 9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Residual Gastric Volume Assessed by Preoperative Gastric Ultrasound | Preoperatively, before induction of anesthesia (single assessment) | Gastric ultrasound will be performed in both the supine and right lateral decubitus positions. Gastric volume will be estimated from the antral cross-sectional area measured in the right lateral decubitus position using the Perlas formula \[GV (mL) = 27 + 14.6 x CSA - 1.28 x age\] and normalized to body weight (mL/kg). The distribution of residual gastric volume will be reported as mean, standard deviation, median, interquartile range, and minimum-maximum values. | ClinicalTrials.gov |
| Secondary | Prevalence of High Aspiration Risk | Preoperatively, before induction of anesthesia (single assessment) | Proportion of patients classified as having high aspiration risk, defined as Perlas Grade 2 (fluid visible in both supine and right lateral decubitus positions) and/or gastric volume \>1.5 mL/kg. Prevalence will be reported with 95% confidence interval | ClinicalTrials.gov |
| Secondary | Correlation Between HbA1c and Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Correlation between preoperative HbA1c level (%) and weight-normalized gastric volume (mL/kg), assessed using Pearson or Spearman correlation coefficient. | ClinicalTrials.gov |
| Secondary | Correlation Between Diabetes Duration and Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Correlation between duration of diabetes mellitus (years) and weight-normalized gastric volume (mL/kg), assessed using Pearson or Spearman correlation coefficient. | ClinicalTrials.gov |
| Secondary | Effect of GLP-1 Receptor Agonist Use and Timing of Last Dose on Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Weight-normalized gastric volume (mL/kg) compared between GLP-1 receptor agonist users and non-users. Among users, gastric volume will be compared between patients whose last dose was taken ≤7 days and \>7 days before the preoperative assessment | ClinicalTrials.gov |
| Secondary | Effect of Insulin Use on Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Weight-normalized gastric volume (mL/kg) compared between patients using and not using insulin therapy. | ClinicalTrials.gov |
| Secondary | Correlation Between Preoperative Fasting Duration and Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Correlation between preoperative solid and clear fluid fasting durations (hours) and weight-normalized gastric volume (mL/kg), assessed using Pearson or Spearman correlation coefficient. | ClinicalTrials.gov |
| Secondary | Correlation Between Gastroparesis Cardinal Symptom Index (GCSI) Score and Gastric Volume | Preoperatively, before induction of anesthesia (single assessment) | Correlation between total GCSI score (range 0-5, higher scores indicate more severe gastroparesis symptoms) and weight-normalized gastric volume (mL/kg), assessed using Pearson or Spearman correlation coefficient. | ClinicalTrials.gov |
| Secondary | Incidence of Postoperative Clinical Aspiration | Up to 48 hours after surgery | Number of patients developing clinical signs of pulmonary aspiration (fever, cough, dyspnea, new pulmonary infiltrate on chest radiography) or aspiration pneumonia, and postoperative nausea and vomiting, assessed from medical records. | ClinicalTrials.gov |
