Official title
Comparison of the Diagnostic Accuracy of Bedside Gastric Ultrasonography and Chest Radiography for Verification of Nasogastric Feeding Tube Placement in Intensive Care Unit Patients: A Prospective Observational Study
Overview
his study evaluates the diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement in intensive care unit patients, using chest radiography as the reference standard. Sensitivity and specificity of bedside ultrasonography will be calculated to assess its performance in this clinical setting.
Primary outcome measures
- Diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement [Time frame: Immediately after nasogastric tube placement]
Secondary outcome measures (2)
- Agreement between bedside gastric ultrasonography and chest radiography [Time frame: Immediately after nasogastric tube placement]
- Time to confirmation of nasogastric tube placement [Time frame: From tube insertion to confirmation]
Eligibility criteria
