Rapid Diagnostic Technology for AUGIB Based on Analysis of VOCs in Exhaled Breath
Sponsor: Beijing 302 Hospital
Summary
This study aims to develop a non-invasive and rapid diagnostic technology for acute upper gastrointestinal bleeding (AUGIB) by analyzing volatile organic compounds (VOCs) in exhaled breath. Clinically confirmed patients will be divided into three groups (no bleeding, minor bleeding, major bleeding) based on endoscopic findings. VOC profiles will be analyzed to construct a predictive model, validated for sensitivity and specificity (both targets ≥0.7). This approach addresses the limitations of endoscopy in emergency or resource-limited settings, improving diagnostic efficiency and reducing mortality.
