BBCMADE Nomogram Validation for High-Risk Gastric Content in Sedative Endoscopy
Sponsor: Fusun Gozen
Summary
This prospective observational study aims to validate the BBCMADE nomogram (Body Mass Index, Brain infarction, Cirrhosis, Male sex, Age, Diabetes, Esophageal reflux) for predicting high-risk gastric content in patients undergoing elective sedative gastrointestinal endoscopy in a Turkish population. Nomogram-predicted risk scores will be compared against the gold standard - endoscopically measured gastric volume and content. High-risk gastric content is defined as gastric volume ≥25 mL, pH \<2.5, or presence of solid content. The nomogram is a non-invasive, web-based, easily applicable screening tool that requires no additional training or equipment, and may contribute to safer anesthesia management by identifying high-risk patients prior to the procedure.

BBCMADE Nomogram
The BBCMADE nomogram (Body Mass Index, Brain infarction, Cirrhosis, Male sex, Age, Diabetes, Esophageal reflux) is applied to predict high-risk gastric content prior to elective sedative gastrointestinal endoscopy. Nomogram scores are compared against the gold standard endoscopic measurement of gastric volume and pH to prospectively validate the model in a Turkish population.
Endoscopic Gastric Volume and pH Measurement
Gold-standard assessment of gastric contents is performed during endoscopy. Gastric volume ≥25 mL, pH \<2.5, or the presence of solid content is defined as high risk for pulmonary aspiration.
