About this study
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
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement
Diagnostic accuracy of bedside gastric ultrasonography will be assessed by calculating sensitivity and specificity using chest radiography as the reference standard.
Measured: Immediately after nasogastric tube placement
Secondary outcomes (2)
Agreement between bedside gastric ultrasonography and chest radiography
The level of agreement between bedside gastric ultrasonography and chest radiography findings will be evaluated.
Measured: Immediately after nasogastric tube placement
Time to confirmation of nasogastric tube placement
Time required to confirm correct nasogastric tube placement using bedside gastric ultrasonography and chest radiography.
Measured: From tube insertion to confirmation

Questions about this trial
What is this clinical trial studying?
An observational study of Intensive Care (ICU), run by Tepecik Training and Research Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 29 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Güldem Turan, Prof (+905332161576, gturanmd@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diagnostic accuracy of bedside gastric ultrasonography for confirmation of nasogastric tube placement (time frame: Immediately after nasogastric tube placement). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2026.
