Brief Summary

This prospective observational study evaluated the role of bedside ultrasound in confirming endotracheal tube placement in adult patients who underwent endotracheal intubation in the emergency department. Correct placement of the endotracheal tube is critical because unrecognized incorrect placement may cause hypoxemia, hypoxic brain injury, or death. In this study, bedside ultrasound was performed during or immediately after endotracheal intubation without interfering with the intubation procedure. Ultrasound findings were compared with capnographic end-tidal carbon dioxide measurement, which was used as the reference method for confirming tube placement. The main aim was to assess whether bedside ultrasound is a useful and reliable method for confirming endotracheal tube position in emergency department patients.

Bedside ultrasound; Point-of-care ultrasound; Endotracheal tube placement; Capnography; Endotracheal tube confirmation

Outcome Measures

Primary Outcomes (1)

• Diagnostic Accuracy of Bedside Ultrasound for Confirmation of Endotracheal Tube Placement

  The diagnostic accuracy of bedside ultrasound for confirming endotracheal tube placement will be evaluated by comparing ultrasound findings with capnometric end-tidal carbon dioxide measurement, which will be used as the reference method. Diagnostic performance will be assessed using sensitivity, specificity, positive predictive value, negative predictive value, overall accuracy, and agreement with the reference method.

  During or immediately after endotracheal intubation, within a maximum of 20 seconds

Study Arms (1)

Patients Undergoing Endotracheal Intubation in the Emergency Department

Adult patients who underwent endotracheal intubation in the emergency department were included in this cohort. Endotracheal intubation was performed as part of routine emergency care. Bedside ultrasound was performed during or immediately after intubation by trained emergency physicians without interrupting the procedure. Ultrasound findings were compared with capnometric end-tidal carbon dioxide measurement, which was used as the reference method for confirming endotracheal tube placement.

Eligibility Criteria

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

Study Population

The study population consisted of adult patients aged 18 years or older who presented to the Emergency Department of Antalya Training and Research Hospital and underwent endotracheal intubation as part of routine emergency care. Patients were included after ethics committee approval if bedside ultrasound and capnometric end-tidal carbon dioxide assessment were performed for confirmation of endotracheal tube placement.

You may qualify if:

• Patients aged 18 years or older
• Patients who underwent endotracheal intubation in the emergency department as part of routine emergency care
• Patients in whom bedside ultrasound and capnometric end-tidal carbon dioxide assessment were performed for confirmation of endotracheal tube placement

You may not qualify if:

• Patients younger than 18 years of age
• Patients with missing or incomplete study data
• Patients with ultrasound images of insufficient quality for evaluation
