BBCMADE Nomogram Validation for High-Risk Gastric Content in Sedative Endoscopy (BBCMADE)
Prospective Validation of the BBCMADE Nomogram for Predicting High-Risk Gastric Content in Patients Undergoing Elective Sedative Gastrointestinal Endoscopy
연구 개요
상태
상세 설명
Pulmonary aspiration of gastric contents accounts for 10-30% of anesthesia-related deaths. Standard fasting guidelines do not guarantee adequate gastric emptying in all patients. The BBCMADE nomogram, developed and validated by Yan et al. (2024) in a Chinese population, demonstrated high discriminatory power for predicting high-risk gastric residual content in outpatients undergoing sedative GI endoscopy. This study will prospectively evaluate its validity in a Turkish population (n=533).
The seven predictor variables (BMI, history of cerebral infarction, cirrhosis, male sex, age, diabetes, gastroesophageal reflux) will be recorded preoperatively and entered into the web-based nomogram interface. Endoscopic gastric volume measurement will serve as the gold standard. Discriminatory performance will be assessed by AUROC. Secondary analyses will include sensitivity, specificity, PPV, NPV, and subgroup analyses.
Sample size: 533 patients (prevalence ~13%, α=0.05, power=95%, 15% dropout allowance; calculated using G*Power 3).

Study Cohort
Patients scheduled for elective sedative gastrointestinal endoscopy.
Gastric volume and pH were measured endoscopically during the procedure.
Patients were classified as high or low aspiration risk based on endoscopic measurements.
The BBCMADE nomogram score was calculated for each patient and compared against the endoscopic findings to validate its predictive accuracy.
|
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.
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.
