Correlation Study Between SMA Blood Flow Reactivity and Acute Gastrointestinal Injury in Critically Ill Patients

NCT07001943

This study aims to address the challenges of enteral nutrition support in critically ill ICU patients with varying gastrointestinal function. We'll use bedside Doppler ultrasound to monitor superior mesenteric artery (SMA) blood flow changes post - feeding, exploring its correlation with Acute Gastrointestinal Injury (AGI) and other hemodynamic indicators. Our goals are to identify the patterns of SMA blood flow changes, establish a predictive model linking SMA blood flow reactivity to AGI risk, and propose individualized enteral nutrition strategies based on intestinal hemodynamics. Through this innovative approach, we hope to enhance the safety of enteral nutrition, reduce AGI incidence, and improve patient outcomes.
