Development and Validation of a Risk Prediction Model for Gastric Retention in Patients Undergoing Sedated Gastroscopy

Sponsor: Zhejiang University

View on ClinicalTrials.gov

Summary

Gastric retention not only compromises the quality of endoscopic examination but also significantly increases the risk of reflux and aspiration in sedated patients. Aspiration of gastric contents represents a critical anesthesia-related complication during the perioperative period, carrying substantial implications for anesthetic management. With the growing volume of sedated gastroscopy procedures, predicting gastric retention has become an urgent clinical priority. This prospective study aims to establish a standardized gastric residual volume (GRV) grading system to evaluate both the volume of retained gastric contents and its contributing factors in patients undergoing upper gastrointestinal endoscopy. We will systematically assess the impact of demographic characteristics, comorbidities, and medication history on gastric emptying function. This study will facilitate establishment of an endoscopy-based simplified assessment system for gastric retention.
