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.

Outcome Measures
Primary Outcomes (1)
Change in Gastric Volume Estimated by Ultrasound
Dynamic changes in gastric volume estimated using ultrasound-derived antral cross-sectional area measurements at predefined time points before and after enteral feeding.
Baseline and up to 60 minutes after enteral feeding
Study Arms (3)
Standard Enteral Nutrition
Mechanically ventilated intensive care unit patients receiving standard enteral nutrition as part of routine clinical care.
Specialized Enteral Nutrition
Mechanically ventilated intensive care unit patients receiving specialized enteral nutrition formulations according to routine clinical practice.
Water Administration
Mechanically ventilated intensive care unit patients receiving water administration via nasogastric tube as part of routine care.
Interventions
Enteral nutrition administered according to routine clinical practice without protocol-driven assignment or modification.
Eligibility Criteria
The study population consists of adult patients aged 18 years and older who are mechanically ventilated and admitted to the intensive care unit. Eligible patients are those receiving enteral nutrition via a nasogastric tube as part of routine clinical care and who are hemodynamically stable. Patients will be observed prospectively without any protocol-driven intervention.
You may qualify if:
- 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
You may not qualify if:
- 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
