Ultrasound vs Chest X-ray for NG Tube Placement in ICU

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.

Treatment and study plan

Primary outcomes

  1. Diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement

    Time frame: Immediately after nasogastric tube placement

    Diagnostic accuracy of bedside gastric ultrasonography will be assessed by calculating sensitivity and specificity using chest radiography as the reference standard.

Secondary outcomes

  1. Agreement between bedside gastric ultrasonography and chest radiography

    Time frame: Immediately after nasogastric tube placement

    The level of agreement between bedside gastric ultrasonography and chest radiography findings will be evaluated.

  2. Time to confirmation of nasogastric tube placement

    Time frame: From tube insertion to confirmation

    Time required to confirm correct nasogastric tube placement using bedside gastric ultrasonography and chest radiography.
