Ultrasound Assessment of Gastric Emptying in Mechanically Ventilated ICU Patients
Trial Parameters
Brief Summary
This prospective observational study aims to evaluate dynamic changes in gastric volume and gastric emptying time using bedside gastric ultrasound in mechanically ventilated intensive care unit patients. The study compares gastric emptying patterns among patients receiving different types of enteral nutrition solutions as part of routine clinical care.
Eligibility Criteria
Inclusion Criteria: * Age 18 years or older * Mechanically ventilated patients admitted to the intensive care unit * Presence of a nasogastric tube * Hemodynamically stable patients receiving enteral nutrition as part of routine clinical care Exclusion Criteria: * Recent abdominal surgery within the first 24 hours * Major abdominal trauma or burns * Significant ascites * Inadequate ultrasound window (e.g., severe meteorism) * Hemodynamic instability * Contraindication to enteral nutrition
