Brief Summary

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.

Conditions

Intensive Care (ICU)

Keywords

Nasogastric Tube Placement, Point-of-Care Ultrasonography, Diagnostic Accuracy Chest X-ray , Intensive Care Unit

Outcome Measures

Primary Outcomes (1)

• 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.

  Immediately after nasogastric tube placement

Secondary Outcomes (2)

• Agreement between bedside gastric ultrasonography and chest radiography

  Immediately after nasogastric tube placement

• Time to confirmation of nasogastric tube placement

  From tube insertion to confirmation

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

The study population consists of adult patients (aged 18 years and older) admitted to the intensive care unit who have a clinical indication for nasogastric tube placement. Eligible patients are enrolled prospectively following written informed consent obtained from the patient or a legally authorized representative.

You may qualify if:

• Age ≥ 18 years
• Clinical indication for nasogastric tube placement
• Written informed consent obtained from the patient or a legally authorized representative

You may not qualify if:

• Refusal to participate in the study
• Age \< 18 years
• Pregnancy
• Contraindications to nasogastric tube placement, including:
• Facial trauma
• Basilar skull fracture
