Accuracy of Ultrasonography in Confirming Correct Positioning of Nasogastric Tube in the Intensive Care Setting

The goal of the study was to test whether a sonographic examination instead of an X-ray allows the position of a tube in the stomach to be checked.

Participants were patients admitted at an intensive care unit who required a nasogastric tube for several reasons (for example nutrition). After obtaining an informed consent from the patient or the family, the researchers checked the position of the tube with ultrasound and compared it with the gold standard, which is radiography. Data analysis allowed the concordance between the two tests to be analyzed.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • age ≥ 18 years
  • an already inserted nasogastric tube or required nasogastric tube insertion
  • no contraindication for chest or abdominal X-ray
  • no contraindication for neck and upper abdominal ultrasonography

Exclusion criteria

  • pregnancy
  • basal skull fractures
  • facial fractures
  • previous or recent surgery of the neck, esophagus or stomach

Treatment and study plan

ultrasonography to confirm the correct placement of a nasogastric tube in the stomach

Diagnostic Test

The sonographic examination consisted of three parts: neck scan, epigastric scan, and injection test using a mixture of 25 mL NaCl 0.9% and 25 mL room air through the nasogastric tube to detect dynamic fogging

Primary outcomes

  1. Diagnostic accuracy of ultrasonography in determining correct nasogastric tube placement in the stomach

    Time frame: Through study completion (enrollment of approximately 180 patients)

    In order to assess its diagnostic accuracy (sensitivity, specificity, negative predictive value, positive predictive value) we compared the index test (ultrasonography) against the reference standard (X-ray)
